SAFE WORKING AT HEIGHT (GUEST POST)

From Jason of riskatmedia.com 

There are particular hazards associated with working at height, some of these hazards accompany almost all types of work activity, such as manual handling and slips and trips.  Others, such as falls from height and contact with moving or falling objects are of particular concern to personnel who work at height.  Falls from height are the leading cause of fatal injuries at work. While contact with moving or falling objects is the third greatest cause of workplace fatality and the second greatest cause of major accidents at work. 

Manual Handling  Manual handling related activities are a major cause of occupational injury.  Low back pain, joint injuries and repetitive strain injuries affect over a million people each year, and many of these injuries are the result of manual handling. Prior to carrying out any unavoidable manual handling activity, you should help to protect yourself from injury by following good manual handling practices.  Consider the task to be carried out and the nature of the load, and be aware of your own capabilities and the environment in which you are working. In particular, tools, equipment and materials can be extremely heavy and you should give consideration to safe manual handling practices before undertaking any job that involves lifting these items while working at height, where manual lifts may be made more difficult by space restrictions and the potential to fall. 

Slip, Trips and Falls  Slips and trips represent a significant cause of work related injury.  Slips and trips can result from contamination, obstacles, inappropriate footwear, reduced visibility, the environment and people’s attitudes. It is extremely important that elevated work platforms and access ladders are kept clear of slip and trip hazards that could result in a possible fall from height.  By removing waste materials to waste skips you can contribute significantly to good housekeeping.  You can also reduce the risk of slips and trips by properly routing any cables that you use, by only taking the tools, equipment and materials necessary to the job aloft, by appropriately storing all such items and keeping walkways clear, by ensuring that you always wear appropriate footwear, and by taking responsibility for your own and your colleagues safety and containing any spills that you might discover. Scaffolders should ensure that no loose scaffolding materials are ever left on a finished scaffold. 

Contact with Moving or Falling Objects  Contact with moving or falling objects is a significant hazard to personnel involved in work at height, as well as to personnel who may be working in the areas beneath operations conducted at height.   Access to the area in which you are working from a ladder should be restricted by barriers when moving vehicles, trailers and hand bogies pose a collision risk.  Suitable barriers and signs should be used to keep the access roads used by Mobile Elevated Work Platforms clear. This will reduce the risk of collision with structures, people and other mobile plant and vehicles.  Care should still be taken to ensure that the platform’s boom or knuckles do not impede the access and working areas used by other plant and vehicles. 

Safe working practices should always be followed to prevent the fall of materials from a height.  All tools, equipment and materials essential to work aloft should be appropriately stowed to ensure that they do not fall.  Any excess materials and all debris should be removed from elevated work platforms, all loose items should be placed in storage boxes, bagged or secured where possible, edge protection should be used to prevent items falling from sloping roofs and all items you need to carry while using a ladder should be held in a belt pouch.  Where there is still a possibility that materials may fall from a height, access to the work area should be restricted by barriers and appropriate warning signs or by posting a banks-man. 

Elevated Working Platforms  Where work at height cannot be avoided, safe working practices should always be followed to reduce the risk of falling any distance which could cause injury.  You should always use an approved and safe means of gaining access to elevated working platforms.  Wherever possible, work at height should be carried out from an appropriate working platform with edge protection, making use of a safety harness and any other available work equipment and fall arrest systems to prevent falls from height.  Where this is not possible, work of a light nature and short duration can be undertaken from a ladder, while other work can be undertaken by suitably trained, experienced and medically fit individuals using a body harness and other fall arrest equipment identified during detailed planning.  You should never use temporary makeshift working platforms.

Work platforms on scaffolding should have full guardrails and toe boards.  A safety harness is required if full guarding is not possible, or if the work involves reaching over. Mesh should be installed if scaffolding is designed specifically to store bulk materials. 

Appropriate fall arrest equipment attached to a suitable anchor point inside the platform should be used whenever you work from a mobile elevated work platform. 

Edges of roofs from which a person could fall should be provided with a barrier that is properly constructed, anchored and fitted with toe boards as appropriate.  Roof openings should be protected by barriers or covers.  Fragile roof areas should be identified and protected by a barrier, or fitted with crawling boards, crawling ladders or duck boards that are properly supported.

Where ladders must be used, they should be securely lashed at the top, tied at the bottom, or held by a second person to ensure that they do not move or slip.  Ladders should be long enough to allow 3 or 4 rungs above the working step, 3 points of contact should be maintained at all times and a harness clipped to a secure anchor point should always be used. 

Structural Integrity  Elevated working platforms should be structurally sound to prevent accidents which could lead to falls from height.  All scaffolding should be erected by trained and competent personnel, they should verify that all materials are fit for purpose and that the load bearing ground and surfaces are fit for purpose.  Never be tempted to make unauthorised alterations to scaffolding. Prior to using any scaffolding on site, you must check that the scaff tag is in date and valid.  Scaffolding should be inspected weekly and following adverse weather conditions by a competent person.  If you are at all unsure that the appropriate inspections have been carried out, do not use the scaffolding and report to your manager. 

All ladders should also conform to the relevant Standard, be free from patent defect, and be inspected once a week by a competent person.  If you have any reason to doubt that a ladder has been appropriately inspected, do not use it and report to your manager.

Lanyards should be inspected before each use and should be subjected to a detailed inspection by a competent person at least once every six months.  If you have reason to think that any fall arrest equipment has not been properly inspected, please do not use it and discuss the matter with your manager. 

Planning  To reduce the risk of personnel falling all work at height should be suitably planned. Where the use of a body harness cannot be avoided for work at height, a competent manager should provide a plan which incorporates safe access and egress, as well as the type of harness and double lanyard that should be used. 

A suitable rescue plan should also be in place where a harness or restraints are used.  The rescue plan should ensure that effective communication links have been established so that assistance can be summoned. 

Training  All personnel need appropriate training and experience to safely carry out operations which involve working at height.  Only suitably trained and authorised personnel are allowed to use mobile elevated work platforms and body harnesses.  Cradles should only be used by personnel who are suitably trained and experienced. 

Human Factors  Human factors play a significant role in safe working at height.  For this reason, personnel should not work at height if you are tired or otherwise unable to give your full attention to the task at hand.  If you feel that your medical history, age, health or fitness might affect your ability to carry work at height, please discuss this with your manager.  Remember that you should never come to work in possession of, or under the influence of, alcohol or drugs.  These substances expose everyone on site to risks that are unnecessary and easily avoided. 

Environments  The risks associated with work at height can be increased by the environment in which you are required to work, Hot and cold environments can result in physical stresses and affect concentration, as they have the potential to raise or lower you body core temperature beyond safe limits.  Confined spaces limit your ability to move around, can be poorly lit and may increase the length of time taken to provide medical assistance in the event of an emergency. It is therefore extremely important that you follow safe working practices when working at height in these environments. 

Hot Works  Particular attention should be given to establishing a safe place of work and to following safe working practices when you carry out hazardous tasks, such as hot works, at height.  The risks associated with fumes, explosions and electric shock can result in falls from height.  Ensure that you use appropriate Personal Protective Equipment, or PPE, that you use and store gas bottles safely and that all items of electrical equipment carry a valid appliance testing label. 

Personal Protective Equipment PPE  PPE is an important means of reducing the risks associated with work at height.  At least standard PPE with safety glasses, construction hard hats and gloves should be worn, with a harness attached to suitable fall arrest equipment while accessing or working on elevated platforms.  Additional PPE, such as dust masks, breathing apparatus and hearing protection may be required for particular tasks, as outlined in the relevant risk assessment.

You should also wear close fitting garments, not wear a tie or jewellery and tie back long hair and long beards to reduce the risk of entanglement.  Only PPE in good working condition will reduce the hazards associated with your work, so it is important to remove, clean and store your PPE correctly. 

Electricity and Overhead Power Lines  Electric shock can result in death and severe burns.  In addition, serious injury can occur if an individual falls from height as a result of an electric shock. All items of electrical equipment should carry a valid test certificate or label to reduce the risk of electric shock.  Testing should be carried out by suitably trained individuals.   If any item of electrical equipment does not carry a valid test label, it should not be used and you should inform your manager.  You should also carry out a visual pre-use inspection of all equipment to ensure that it remains undamaged. 

Because of the risk of electrocution, aluminium ladders should never be used where there is a risk of contact with electricity.

Electric shock can also occur as a result of contact with overhead power lines.  Where mobile elevated work platforms are to be used near overhead power lines, an appointed person should plan and supervise operations.  Power lines should be made dead where at all possible.  Where this is not possible, work under power lines should be of short duration and all appropriate restraints and barriers should be in place to ensure that the platform cannot reach or accidentally come into contact with live power lines. 

Mobile Elevated Work Platforms MEWPs   Other safe working practices are necessary to prevent mobile elevated work platforms from overturning during work at height.  The manufacturer’s safe working load should never be exceeded and the platform should never be operated in high winds.  You should also avoid handling sheet type materials in windy conditions.

Where the use of a platform on uneven ground cannot be avoided, they should be used at reduced speed, they should not be turned on slopes and the use of road plates should be considered. 

Emergency Procedures  In the event of an emergency while working at height, isolate any equipment that you have been using, make your work area safe and use a safe means of egress to evacuate the area according to the site emergency procedures.  If you are involved in an accident, seek immediate assistance.

KEEPING THE CONSTRUCTION INDUSTRY SAFE (GUEST POST)

1 Comment

Construction is a notoriously dangerous industry.  In the UK, where we are based, the industry employs around five percent of the country’s workforce.  According to government statistics thosefive percent have twenty-two percent of the work related fatal injuries and ten percent of the reported major injuries.  In the US, seventeen percent of worker fatalities are in the construction industry. 

As shocking as these statistics sound, there’s been a significant improvement in both countries over the last forty years.  I think the reasons for this are threefold.  Firstly, there is much more safety legislation nowadays than formerly.  Secondly there’s a much more consistent use of safety clothing and equipment – much of which you can study at leisure on this site.  Thirdly, more workers receive various forms of safety training.  I firmly believe that the way to continue to improve safety in construction is to make training and refresher courses widely available for people employed in the industry and I also think that it’s in the construction companies’ best interest to ensure that their employees can access training.  Why do I believe this?  Well, there are several reasons: 

1)      Companies can be financially liable for the safety of their employees.  Even with insurance your premiums will go up dramatically if you have accidents on your sites.

2)      Companies generally want to employ the best workers.  If you have a good reputation for safety practice, people are more likely to want to join you and stay with you.  If your employees see that you’re willing to develop their skills, they’re much more likely to stay loyal to you.

3)      Workers are often injured by the actions of other workers.  Think about it – how likely is it that you’ll be fatally injured by a falling object that you’ve dropped? How likely is it that you’ll have put up the scaffolding that’s worked loose and caused you to fall?  The more workers on your site who have safety training, the safer the whole site will be.

4)      Companies can receive site inspections from official bodies.  Some are empowered to fine companies for non-compliance with legislation.  The more knowledgeable your employees are, the less likely you are to have compliance breaches on your sites.

5)      Companies are in a position to request bespoke training from education co-ordinators if they’re putting through a large number of pupils.  This means that the trainer(s) will put your company’s policies and procedures at the heart of their training.  You are also in a position to monitor the way that the training is delivered and make sure that your employees have the skills rather than just the piece of paper at the end of it. 

Are you involved with the construction industry?  Do you have any views on the safety training  you’ve received?  We’d be interested to read your responses in the comments section.

IS ANYONE SAFE AT A NASCAR RACE?

1 Comment

I don’t intend to hang a big, black cloud over the race that is scheduled to start in about one hour, the “Superbowl of Racing,” the Daytona 500.  Race fans look forward to another season of spectacular driving, and talented drivers.  Yesterday’s accident, during the NASCAR Nationwide, marred the victory for veteran driver Tony Stewart, as two cars collided, sending one of the car’s motor and some of its tires through a hole in the fence, caused by the impact, or over the fence, injuring approximately 28 persons.  Fourteen were taken to a nearby hospital and the other fourteen were treated at the track. 

Through the years, NASCAR’s focus has been on safety – not only of the drivers, but also that of the pit crews, tracks, and fans, and of course, safer cars.  Maintaining safety for the cars and drivers is a challenge for both NASCAR and the owners and designers, because cars are becoming faster and faster.  Yesterday’s freak accident may deter some fans from attending, but I am betting most of them will go back for today’s race. 

The accident involved twelve cars, but none of the drivers were injured.  Stewart, when interviewed, stated, “We’ve always known since racing started, this is a dangerous sport, but it’s hard.  We assume that risk, but it’s hard when fans get caught up in it….I could see it all in my mirror, and it didn’t look good from where I was at.” 

One neat thing for female fans, is that Danica Patrick won the pole position for today’s race.  It will be interesting to see where she finishes today.  She is a very tiny person, 5’2”, and around 100 pounds, but she has proven to be as tough as the guys.  Many of the drivers will attest to it.  Jeff Gordon and Carl Edwards both took their daughters to meet her last week, at the Stewart-Haas garage. 

If you plan to attend any NASCAR events, Texas America Safety Company has NASCAR hardhats, which might prove to make you a little safer, and also fun to wear at work.  For sure, you could also use some quality hearing protection earplugs.  It gets noisy out there. 

Let’s send our thoughts and prayers out to those fans who were injured yesterday, that fans, drivers, and crews have a very safe day today and throughout the racing season.

WHAT SHOULD I INCLUDE IN MY CONSTRUCTION SITE SAFETY INDUCTION? (GUEST POST)

2 Comments

Sent by Jason of riskatmedia 

Every week at least one construction worker will die as a result of work-related injuries.  Most of these fatalities involve skilled construction and building workers. Falling from a height is the greatest single cause of fatal injury, followed by being struck by a moving or falling object, contact with electricity, being trapped by something collapsing or overturning and being struck by a moving vehicle. In addition to this, over 3500 construction workers suffer major work-related injuries every year.

There are many dangers involved in working on any construction site.  These hazards are real and often potentially life threatening, but we face them every day and sometimes forget how real and close they may be to all of us. This blog will cover most of the topics required for a Construction Site Induction.

Site Access

Access onto site should always be controlled for safety and security reasons.  This may be by means of a signing in and out procedure, or by means of controlled entry technology.  It is important that you use controlled entry procedures every time you enter or exit the site, this will allow management/security to determine exactly who is on site should an emergency situation arise. 

Personal Protective Equipment – PPE

Personal protective equipment, or PPE, is an important means of reducing the hazards associated with work on a construction site.  The minimum PPE that should be worn on site is a hard hat, appropriate gloves, safety footwear and a high visibility vest or jacket.  This PPE should be worn on site at all times and may be supplemented by additional PPE, such as eye protection, ear defenders, dust masks and a safety harness, as stipulated in your risk assessment and method statement or permit to work.  All items of PPE need to provide a good fit and be in good working condition, so it is important to check your PPE before you use it.  PPE should be stored in a secure, clean and dry environment and any contaminated PPE should be removed carefully, cleaned or disposed of in a safe manner.” 

Alcohol, Drugs and Medical Conditions

It is extremely important that you never come to work in possession of, or impaired by alcohol or drugs. These substances expose everyone on site to risks that are unnecessary and easily avoided. If you have a medical condition, have an active implantable medical device fitted or use prescribed or other medicines, you should report this to your manager/supervisor so that the details can be recorded for use in the event of an emergency.  Any information that you provide should be treated in the strictest confidence. 

Traffic Management and Pedestrian Walkways

Construction sites are busy and noisy environments with mobile plant and vehicles often in close proximity to pedestrians.  For these reasons, designated pedestrian walkways and Egress Routes should been marked out on the site. Stick to these walkways whilst on site and don’t be tempted to take short cuts that might expose you to unnecessary risk.  If you drive on to site, make sure that you stick to the speed limit, that you only park in designated parking bays and that you keep footpaths, access routes and pedestrian walkways clear.  A copy of the most up to date traffic management plan may be displayed on site notice boards, along with other important safety information. 

Welfare Facilities

Welfare facilities should be available on site and may include toilets, a restroom, a washroom and drying room and may include a canteen.  Use these facilities responsibly by helping to keep them clean and tidy and recycling your waste as appropriate. 

Vermin

Vermin are encouraged by the presence of food on site, so it is very important that you only eat in designated areas, that you dispose of food waste appropriately and that you do not take any food on to site.  Vermin, such as rats, can spread diseases, including the serious and possibly fatal disease Leptospirosis. 

Smoking, Music and Mobile Phones

Smoking and music are generally not permitted on construction sites, except in areas designated by site management.  Mobile phones should only be used in lower risk areas, such as offices and welfare facilities, where you are safe and unlikely to affect other workers or operations.  Mobile plant operators and drivers of site vehicles must never use a mobile phone whilst operating or driving. 

Hazardous Substances and Materials

During your work you may use or come into contact with substances such as adhesives, paints or dust, which may harm you or the environment.  If you use these hazardous substances you are required to understand the precautions that must be observed and the PPE that must be used, when transferring, mixing or using these substances.  You are also required to understand the relevant storage, disposal and emergency arrangements.  Information on the substance as well as an assessment of the hazards associated with its use should also be made available.

Any spills of fuels, oils or potentially hazardous substances, should be immediately contained using the appropriate spill kit and then reported to the supervisor or manager so the spill can be safely cleaned up. 

Shots relevant to environmental management

To help reduce the effect of operations on the environment:

  • Reuse and recycle as many materials as possible
  • Compress waste and use waste segregation facilities where possible
  • Dispose of waste responsibly and in accordance with legislation
  • Damp down to minimise dust
  • Turn off any plant or equipment not in use
  • Ensure plant and equipment are well maintained
  • Only use task lighting where necessary
  • Turn off any taps and hoses when not in use and report any leaks 
  • Never pump or pour anything down the drains and only wash down plant and equipment such as cement mixers in the areas provided
  • Where there are trees that need to be protected, please remain within designated work areas and avoid damaging tree routes
  • Do not disturb nesting birds, newts, badgers, bats or invasive weeds
  • Be aware of any habitats or historical remains on site. 

Emergency Fire Procedures

Specific emergency procedures should be followed in the event of a fire.  If a fire occurs, an alarm will sound.  If you hear a fire alarm, stop what you are doing.  Isolate any plant or equipment that you have been using and make your work area safe.  Take the nearest escape route and follow a safe route to the nearest assembly point.  Remain at your assembly point until you are given the all clear to return to work.  Take the time to familiarise yourself with the specific emergency procedures that apply to the site, as well as the location of the assembly points. 

Flammable Materials

To help prevent fires, flammable and combustible material should always be stored safely.  Gas bottles should be stored in secure, vented cages or stores with appropriate warning notices.  When working with gas, always ensure that you do so with adequate ventilation well away from any naked flames. 

Accident Procedures

Construction site rules and procedures are designed to minimise the risks to the safety of everyone who works on site.  But accidents may still happen.   In the event of an accident, first aid facilities should be available on site.  The names of all trained first aiders may be displayed on the site information board.  If you are involved in an accident or a near miss, no matter how minor, please report it to the site management so that they can ensure you get the correct medical treatment and take steps to prevent the incident from recurring.  If you witness a serious accident, get help and send someone for the site manager.  Try not to move the injured person, but do make sure that they are safe. 

Slips, Trips and Falls

Good workmanship and good housekeeping are practices that can help to prevent accidents and fires.  Remember to route power and lighting cables so that they do not pose a potential trip hazard.  Tools, materials and equipment should only be stored where indicated and should be stacked safely.  All access routes and walkways should be kept clear of obstructions, especially those that are used by members of the public including children.  Tidy and clean your work space throughout the day and never leave tools, equipment or materials where they could create a trip hazard. 

Electrical Safety

All items of electrical plant used on site should carry a valid testing certificate or label to ensure Electrical Safety.  If an item of plant does not carry a valid electrical testing label, is damaged or has a missing guard, then please, do not use it.  If you use battery powered tools ensure that batteries are charged in a safe area and do not obstruct welfare facilities or create trip hazards. 

Tower and Mobile Cranes

Tower and mobile cranes may be in use on site, so it is important that you do not enter unloading areas unless you are authorised to do so.  You should also be aware of the fact that plant including cranes, telehandlers and powered access equipment should only be operated by individuals who are suitably trained and authorised to do so.  If you are trained and authorised to operate plant, make sure that you carry out daily pre-use safety checks, that all safety devices and locking pins are in place, that the flashing beacon and any warning devices are working and that all-round visibility aids are in place and effective.  Seek the assistance of a banks-man where visibility is limited and never leave the keys in an unattended machine. 

Work Equipment

Whatever work activity you are carrying out on site you will be using work equipment. Only use the correct tools for the job and only use tools and other work equipment which you have been trained to use. 

Risk Assessment, Method Statement, and Permit to Work

Before you undertake any job, make sure that your supervisor has briefed you, that you have a complete and valid risk assessment and that you are able to and do work according to your method statement.  Be aware that new risk assessments and method statements may be required where jobs have changed or where new hazards have been introduced.  In addition, certain work on site may require a permit or permission to work. These are issued after you have submitted a risk assessment and method statement for a particular job.  If you are unsure whether a particular job requires a permit, ask your supervisor or manager. 

Working at Height

You may remember that falls from height represent the single largest cause of death in the construction industry so Safe Working at Height is essential. It is therefore extremely important that you follow safe working practices when work at height cannot be avoided.  Always use an appropriate working platform or work equipment whenever there is a potential to fall, which includes loading and unloading of vehicles.    Always check your work platform before use, and be especially vigilant in windy, wet or icy weather.  Remember, the use of a harness requires extra competence and is a last resort.  If you operate powered access equipment you must have the appropriate training, certification and authorisation for that particular type of equipment.  You should also carry out and record a daily pre-use inspection.  Ensure that the access equipment is only used on stable ground, that it is not used in high winds, and never use it to lift or transport loads. In a boom type mobile elevated work platform you must wear a full body restraint harness secured to an anchor point by a suitable length, work restraint lanyard. Remember to park the mobile access equipment safely and to remove the key when the machine is not in use.  The use of ladders and stepladders is discouraged and may be permitted only where the task is simple, of short duration, and no safer alternative is possible.  Scaffolding, access ladders and mobile towers may only be erected, dismantled or modified by trained and competent persons.  Remember to lock the wheels and fit the guard rails and to check that the scaff tag is in date and valid. Close all loading bay gates after use and never load materials onto guard rails. 

Excavations and Quick Hitches

Safe working practices are essential when excavating.  Check and mark the location of services, protect services with barriers or road plates, dig trial holes to confirm location and depth and avoid the use of mechanical equipment, picks and forks around pipes and cables.  Don’t enter an excavation unless you have to.  If you do enter an excavation, make sure that the sides are battered, stepped or supported, use a ladder to gain access and put barriers around the edges if there is a potential to fall.

Buckets can become detached from excavators during operations if the appropriate locking pin or device is not properly fitted.  The excavator operator must ensure that the locking pin or device is correctly engaged and secure before commencing operations. 

Manual Handling

Workers in the construction industry suffer considerably higher rates of manual handling related injuries than workers in any other industry.  Help to protect yourself from injury by following good principles of manual handling.  If you must lift a load, assess whether you can lift it alone or whether you need someone to help you.  Remember to consider the environment in which you are working.  Always adopt the correct lifting technique. 

Your Health

Your health is as important as your safety.  Vibration white finger and dermatitis are too often suffered by construction workers.  Protect against these painful conditions by reducing your daily exposure to vibration, wearing the correct PPE and using barrier creams to protect yourself from contact with potential skin irritants such as cement.  Remember to apply sun cream if you are going to be working in direct sunlight. Wear an appropriate dust mask and use vacuums rather than sweeping to clear dust.  Check your tetanus vaccinations are up to date. Never touch discarded needles or syringes.  Stop work and clear any area if you discover a substance you think might be asbestos.  If you discover asbestos or discarded needles, please report this to site management.

POWER TOOL SAFETY (GUEST POST)

1 Comment

By Jason, from RiskAtMedia: 

All work activities carry the potential to cause harm to our own and others’ health and well-being, but we sometimes forget how real and close to us these hazards are.  Every year, a large number of people are killed at work, and an even greater number of people suffer work related injuries because they are unable to follow safe working practices. There are particular hazards associated with the use of powered tools, some of these hazards accompany almost all types of work activity, such as manual handling and slips and trips.  Others are of particular concern to powered tool operators and we will consider these in this Power Tool Safety brief. 

Manual Handling

Manual handling related activities are a major cause of occupational injury.  Low back pain, joint injuries and repetitive strain injuries of various sorts, affect over a million people each year, and many of these injuries are the result of manual handling. Prior to carrying out any unavoidable manual handling activity you should help to protect yourself from injury by following good manual handling practices.  Consider the task to be carried out and the nature of the load, and be aware of your own capabilities and the environment in which you are working. In particular, tools and work pieces can be extremely heavy and you should give consideration to safe manual handling practices before undertaking any job that involves lifting these items. 

Slips, Trips and Falls

Slips, trips and falls represent a significant cause of work related injury.  Slips and trips can result from contamination, obstacles, inappropriate footwear, reduced visibility, the environment and people’s attitudes.  Good workmanship and good housekeeping are practices that can help to prevent accidents and fires.  By removing debris, swarf, packaging and other waste materials to waste skips you can contribute significantly to good housekeeping.  You can also reduce the risk of slips and trips by properly routing any cables or air hoses that you use, by appropriately storing materials, tools and other equipment and keeping walkways clear, by ensuring that you always wear appropriate shoes and by taking responsibility for your own and your colleagues safety and appropriately containing any spills that you might discover. 

Contact Risk

Contact with moving or rotating power tools is a significant hazard to personnel using power tools, as well as to personnel working close by, and can result in serious injury.  All personnel need appropriate training and experience to be able to use work equipment safely.  Never use any work equipment unless you have received suitable training and are qualified and competent to do so.  Before you begin to use a powered tool, make sure that you have read the manufacturer’s instructions for use.  Study the tool to make sure that you know which parts of the tool move, which parts are stationary and which parts are sharp.  Make sure that all guards are in place.  Where appropriate, remember to securely clamp tools or work pieces.  And ensure that you only use tools for the job they were intended to perform, as this can significantly reduce the risk of injury.  To protect others from the risk of contact with the moving or rotating powered tool parts, make sure any necessary warning signs and barriers are in place before you begin work.  You should also take care if you need to walk through or work in an area adjacent to where another person is using powered tools. 

Electrical Safety

Electric shock from powered tools can result in death or severe burns.  Additionally, serious injury can result if the operator falls against a powered tool as a result of the shock.  To prevent the risks posed by electrical hazards, all electric powered tools should carry a valid test certificate or label.  Testing should be carried out by suitably trained individuals.   If an electric powered tool does not carry a valid test label, it should not be used and you should inform your supervisor. 

Malfunction

You should also carry out a visual pre-use inspection of all tools to ensure that they remain undamaged.  If you do discover a defect, please do not use the tool and report the problem to your supervisor.  Never attempt to make temporary repairs to a tool.   You should also observe the tool while it is in use for possible signs of malfunction.  If you notice that the tool is vibrating abnormally, doesn’t sound right, or is displaying signs of any other problem, switch it off and report to your supervisor.  When using an impact wrench, only sockets specifically designed for use with impact wrenches should be used and you should carry out a daily pre-use inspection of the socket to ensure that it is undamaged.  Never use sockets designed for hand ratchets on an impact wrench. 

Maintenance

Ensuring that equipment is appropriately cleaned and maintained is also central to safety.  Clean tools after each use, as a dirty tool is unsafe and is difficult to use.  When you carry out maintenance, make sure that the equipment is isolated and cannot be turned on accidentally.  Ensure swarf has cooled before using gloves and a brush to remove it and clean the tool.  If you need to remove swarf from a running powered tool to prevent long strands developing, make sure that you are not wearing gloves and use a rod to remove the swarf.  Never use a rag to clean a tool while it is running and never use compressed air to clean a tool. 

Entanglement

When using powered tools, wear close fitting garments, do not wear a tie or jewellery and tie back long hair and long beards to reduce the risk of entanglement. 

Personal Protective Equipment PPE

Personal Protective Equipment, or PPE, is an important means of reducing the risks associated with projectile particles produced when using powered tools.  At least standard PPE with safety glasses should be worn.  It may be necessary to screen the work area if projectile particles pose a hazard to individuals working or passing nearby.  Only PPE in good working condition will reduce the hazards associated with your work, so it is important to remove, clean and store your PPE correctly. 

Noise at Work

Hearing loss caused by exposure to noise at work is a significant source of occupational disease, with many people suffering deafness, tinnitus or other ear conditions as a result of exposure to excessive noise levels at work.  The level of noise and how long people are exposed to noise at work both contribute to potential hearing damage.  Noise can be reduced to harmless levels by wearing industiral ear plugs and ear defenders. These items of PPE should therefore always be worn while using impact wrenches, and should also be worn when using other powered tools unless local measurements indicate that noise levels are below the level at which such action is necessary. Controls should also be considered for individuals working in close proximity. 

Human Factors

Human factors also play a role in increasing the risk of injury while using powered tools.  Never come to work in possession of, or under the influence of, alcohol or drugs.  These substances expose everyone to risks that are unnecessary and easily avoided.  You should also not use powered tools if you are overly tired or unwell, as concentration is important to using tools safely. 

Hand Arm Vibration Syndrome HAVS

If you regularly use powered tools, you may be at risk of developing Hand Arm Vibration Syndrome or HAVS.  This condition involves damage to the blood vessels, nerves and joints of the hand, wrist and arm.  It is a painful and debilitating condition, resulting in numbness of the hands to the extent where it is impossible to feel with your fingers and very difficult for you to pick up small objects.  This can make both occupational and leisure activities, such as playing darts, fishing or DIY, impossible.  HAVS is entirely preventable.  Always use the right tool for the job, as this will allow you to complete the job more quickly and will expose you to less hand-arm vibration.  Carry out a pre-use inspection of all hand held equipment and report any damage to your supervisor, as faults and general wear may result in increased vibration.  If you do experience abnormal vibration from hand held equipment, please report this immediately.  Try to reduce the amount of vibration you are exposed to in one go by doing other jobs in between.  Use a relaxed grip and avoid using excessive force on a tool or work piece.  Store tools so that they do not have very cold handles when used next.  Keep your hands warm and dry and take breaks to exercise your fingers regularly.   Wear gloves when using impact wrenches to reduce the effect of vibration. 

Compressed Air

Compressed air is a safe and reliable alternative to electricity for powering impact wrenches and other air powered tools, but it can be dangerous if it is not used responsibly.  In particular, contact with streams of compressed air can penetrate the skin and enter the bloodstream.  All compressed air plant should be appropriately inspected and certified to ensure that it is safe to use.  Never operate air compressors at faster speeds than the manufacturer’s recommendation and ensure that the air intake is from a clean, outside and fresh air source, with screens and filters used to clean the air if necessary.  Unless your tool has a quick disconnect plug, you should always turn off the air supply at the control valve and bleed the tool before disconnecting.  You should never compress, bend or kink air hoses and you should never carry an impact wrench or other tool by the air hose.  And never use compressed air to clean your clothes or yourself. 

Emergency Procedures

In the event of an emergency, isolate any equipment that you have been using and evacuate the area according to the site emergency procedures.  If you are involved in an accident, seek immediate assistance.

SAFE LIFTING OPERATIONS (GUEST POST)

Sent by Jason of Riskatmedia.com

All work activities carry the potential to cause harm to our own and others’ health and well-being, but we sometimes forget how real and close to us these hazards are.  Every year, a large number of people are killed at work, and an even greater number of people suffer work related injuries because they are unable to follow safe working practices. There are particular hazards associated with lifting operations, some of these hazards accompany almost all types of work activity, such as manual handling and slips and trips.  Others, such as contact with moving or falling objects and contact with moving machinery, are of particular concern to personnel involved in lifting operations as they result in a significant number of fatal and serious injuries each year.  In fact, contact with moving or falling objects is the third greatest cause of workplace fatality and the second greatest cause of major accidents at work. 

Manual Handling

Manual handling related activities are a major cause of occupational injury.  Low back pain, joint injuries and repetitive strain injuries of various sorts, affect over a million people each year, and many of these injuries are the result of manual handling. Prior to carrying out any unavoidable manual handling activity you should help to protect yourself from injury by following good manual handling practices.  Consider the task to be carried out and the nature of the load, and be aware of your own capabilities and the environment in which you are working. In particular, lifting accessories, lifted equipment and loads can be extremely heavy and you should give consideration to safe manual handling practices before undertaking any job that involves lifting these items. 

Slips, Trips and Falls

Slips and trips represent a significant cause of work related injury.  Slips and trips can result from contamination, obstacles, inappropriate footwear, reduced visibility, the environment and people’s attitudes.  Good workmanship and good housekeeping are practices that can help to prevent accidents and fires.  By removing waste materials to waste skips you can contribute significantly to good housekeeping.  You can also reduce the risk of slips and trips by properly routing any cables or hoses that you use, by ensuring that a safe place of work is, by ensuring that you always wear appropriate footwear, by considering whether the environment in which you will be working increases the risk of slips and trips and by taking responsibility for your own and your colleagues safety and appropriately containing any spills that you might discover.  Spills involving oil or hydraulic fluids represent a significant hazard, as they present a dangerous slip hazard and also involve substances that are both hazardous and flammable.  It is extremely important that your work area is kept clear of slip and trip hazards during lifting operations, when your own and your colleagues attention will be quite rightly focused on the lifting task at hand. 

Contact Risk

Contact with moving or falling objects is a significant hazard to personnel involved in lifting operations, as well as to personnel working close by, and can result in death or serious injury.  It is therefore vitally important that safe working practices are followed at all times during lifting operations to ensure that loads do not move, swing or fall.  

Training and Approval

All personnel need appropriate training and experience to be able to use work equipment safely.  Never use lifting equipment unless you have received suitable training and are qualified and competent to do so.  You should ensure that you are suitably qualified, competent and, where appropriate, have the necessary certifications to use the particular type of equipment that you will be working on.  All lifting operations should be controlled by an appointed, competent person who should brief all team members before the lifting operation is undertaken. 

The Lift Plan

To reduce the risk of loads moving or falling, all lifts should be planned.  Frequent or routine lifts may be subject to a generic lift plan, supported by an onsite risk assessment and team briefing.  For complex lifts, an individual and detailed lift plan should be documented.  All lift plans should be reviewed and approved by the appointed, competent person.  In particular, lifts should be planned so that personnel will not be standing or working directly beneath a load and so that the load will not be moved directly over people.  The lift plan should also provide an escape route in the event of unexpected movement of equipment or of the load. 

Suitable and Safe Equipment

It is important to ensure that all equipment used during lifting operations is safe and suitable for the job at hand.  Lifting equipment should be subjected to a detailed and thorough examination by a competent person prior to its first use on site, upon installation, when it has been disassembled and reassembled at a new location, if it has been involved in an incident, if it has been overloaded, if it has been subject to modification or major repair to safety critical components, if there have been changes in the condition of its use such as periods out of service, and for equipment used to lift personnel.  If you have any reason to doubt that such an examination has been carried out, do not use the equipment and report to your manager.  In addition, all items of electrical equipment should carry a valid appliance test certificate or label, to reduce the risk of electric shock.  Electric shock can result in death or severe burns. Serious injury can also result if someone falls or becomes incapacitated during lifting operations as a result of electric shock.  Testing should be carried out by suitably trained individuals.   You should also carry out a visual pre-use inspection of all equipment to ensure that it remains undamaged and ensure that all safety devices are fitted and are operational.  If any item of electrical equipment does not carry a valid test label, it should not be used and you should inform your manager. 

Load Integrity and Stability

Establishing load integrity and stability is also essential to reducing the risk of loads swinging, moving or falling during lifting.  All equipment operators and users should be familiar with the safe lifting capacity of the equipment and should understand the effects of changes in configuration.  The safe working load of the lifting system should be assessed, taking into account the configuration of the equipment and the operating environment where appropriate.  This safe working load should never be exceeded.  The load should possess sufficient integrity to withstand the forces applied during lifting and the method of rigging should ensure that the load remains stable and cannot tip, slip, swing or fall unintentionally.  For this reason, all rigging and thorough daily pre-use inspections should be carried out by competent personnel.  During jacking operations a firm level base should be provided against the load so that no sideways forces are present.  Loads should also be checked in increments to prevent the limit of the jack stroke from being reached. 

Human Factors

To reduce to risk of injury to other personnel from swinging, moving or falling loads, all non-essential personnel should be excluded from the area in which lifting operations are taking place.  Barriers and warning signs should be used where appropriate to facilitate this, especially as people can make mistakes and may break the rules.  These and other human factors play a significant role in safe lifting. Personnel should not undertake more than one task at a time during lifting operations and you should not take part in lifting operations if you are tired or otherwise unable to give your full attention to the task at hand. You should never come to work in possession of, or under the influence of, alcohol or drugs.  These substances expose everyone on site to risks that are unnecessary and easily avoided. 

Communication

Communication is a vital part of safe working practices during lifting operations.  The lifting appliance operator needs to be able to understand and obey an emergency stop signal no matter who gives it, and any member of the lifting team needs to be able to issue an emergency stop signal.  It is therefore vital that all members of the lift team establish, test and understand the verbal, hand signal or radio communications that will be used during the lift, prior to lifting. 

Personal Protective Equipment PPE

Personal Protective Equipment, or PPE, is an important means of reducing the risks associated with lifting operations.  At least standard PPE with safety glasses, a hard hat and industrial work gloves should be worn.  Only PPE in good working condition will reduce the hazards associated with your work, so it is important to remove, clean and store your PPE correctly.

Noise at Work

Hearing loss caused by exposure to noise at work is a significant source of occupational disease, with many people suffering deafness, tinnitus or other ear conditions as a result of exposure to excessive noise levels at work.  The level of noise and how long people are exposed to noise at work both contribute to potential hearing damage.  Noise can be reduced to harmless levels by using ear plugs and ear defenders in high noise areas. 

Emergency Procedures

In the event of an emergency while conducting lifting operations, lower any suspended loads, isolate any equipment that you have been using, make your work area safe and evacuate the area according to the site emergency procedures.  If you are involved in an accident, seek immediate assistance.  Lifting operations should never be carried out alone.

THINGS YOU MAY NOT KNOW ABOUT TRAINS, PART I

Have you ever wondered as you drive down the highway about those trains you see rolling along, and what on earth could be in all those cars?  You also see lots of graffiti, done by some local “artists” along the way, and can’t help but question all the places that train has been.  One thing you need to understand, is that many of those cars are carrying hazardous materials, and in the event of a derailment, or spill, you need to drive away from the area as soon as possible. 

Railroad companies are overseen primarily by the Federal Railroad Administration, but also answer to the Department of Transportation, and the National Transportation Safety Board.  No person may transport a hazardous material in commerce unless that material is properly classed, described, packaged, marked, labeled, and placarded and is in condition for transportation according to DOT regulations.  Railroad Company computers are able to track the trains at all times. 

For your information, here are the hazard classes and divisions:

  • 1 – Explosives (1.1 – Explosive with mass explosion hazard; 1.2 – Explosive with projection hazard; 1.3 – Explosive with predominantly fire hazard; 1.4 – Explosive with no significant blast hazard; 1.5 – Very insensitive explosive; blasting agent, and 1.6 – Extremely insensitive detonating substance.)
  • 2. – Gases (2.1 – Flammable gas; 2.2 – Nonflammable, nonpoisonous, (nontoxic), compressed gas; and 2.3 – Poisonous (toxic) gas (by inhalation).
  • 3 – Flammable Liquids
  • 4 – Flammable Solids and Reactive Solids/Liquids (4.1 – Flammable solid; 4.2 – Spontaneously combustible material, and 4.3 – Dangerous when wet marked.)
  • 5 – Oxidizers and Organic Peroxides  (5.1 – Oxidizer; 5.2 Organic peroxide.)
  • 6 – Poisonous (Toxic) Materials/Infectious Substances (6.1 – Poisonous (Toxic) material; 6.2 – Infectious substance.
  • 7 – Radioactive Materials
  • 8 – Corrosive Materials
  • 9 – Miscellaneous Hazardous Materials

Worded Classes

Combustible Liquids (regulated in bulk packaging only)

ORM-D (Other Regulated Materials – D) (regulated in air transportation only; not regulated in rail transportation. 

Shipping hazardous materials are time-sensitive.  Those under a 20-day time limit to arrive are:

  • 1.      Ethylene, refrigerated liquid
  • 2.      Hydrogen, refrigerated liquid
  • 3.      Chloroprene, stabilized
  • 4.      Flammable liquid, N.O.S.
  • 5.      Hydrogen chloride, refrigerated liquid
  • 6.      Vinyl fluoride, stabilized

Those having a 30-day shipping limit are:

  1. Styrene monomer, inhibited
  2. Flammable Liquid, (Recycled styrene) 

When transporting hazardous material shipments in a train, a member of the train crew must also have acceptable emergency response information and a document showing the current position of each hazardous material in the train.  This documentation provides railroad and emergency response personnel with accurate information for every hazardous material being transported. 

Next, In Part II, we will talk about what type of training railroad crews experience to be prepared for a hazardous material spill caused by a railroad derailment or railroad car leak.  Please read on…..

THINGS YOU MAY NOT KNOW ABOUT TRAINS – PART II

Occasionally, we hear about a train derailment, or the spill of a hazardous material from a train car.  Today, we will share typical instructions that are given to railroad personnel in case of such an occurrence.  First, the train crew should notify the train dispatcher of such a derailment and the location where the train crew will meet the emergency response personnel.  

SAFETY IS OF THE MOST IMPORTANCE.  (THIS MEANS SAFETY TO YOU, THE OTHER EMERGENCY RESPONSE PERSONNEL AND THE PUBLIC.) THE FIRE CHIEF IS IN COMMAND – DO NOTHING WITHOUT HIS AUTHORITY. 

As earlier mentioned, railroad authorities notify train personnel of such a derailment and the location of their crew. At the time the railroad company notifies the 911 dispatcher of a hazardous spill, the dispatcher must ask the railroad the location of the train conductor, who will have all the shipping papers in his possession. 

Know what you are dealing with first; do not get over anxious and go into an area with a derailed car that has hazardous material leaking.  Take note of the wind direction and which area should be evacuated first, should an evacuation be necessary.  Establish a command center at this point and notify all people involved with this incident of its location.  The evacuation should be handled by the local Police Department. 

It is the primary job of the railroad personnel to protect the public from fumes, fire or possible explosion that may occur from a hazardous material spill.  At some point the fire chief will determine if outside help (county, state, federal) is needed and notify the mayor to start the phone calls for assistance.  Containment and blockades will be the responsibility of the public works department. 

The spill area belongs to the emergency response personnel under the supervision of the fire chief until the proper hazardous material personnel arrive on the scene to take over.  The fire chief still remains in command of the area until such time as he and other specialists consider it safe.  Railroad personnel are highly trained and equipped for these situations, and should keep thing under control. 

If EMS personnel and ambulances are not immediately needed, they should wait in the immediate area of the command center and at the fire chief’s disposal.  Railroad company personnel should be equipped with the proper PPE (personal protective equipment) to ensure compliance with all safety requirements, as well as protection for their safety. 

In the event of an accident involving a train, there is no place for onlookers.  Keep a safe distance away, or find another route.

MACHINING SAFETY (GUEST POST)

Sent by Jason, of riskatmedia.com. 

All work activities carry the potential to cause harm to our own and others’ health and well-being, but we sometimes forget how real and close to us these hazards are. Every year, a large number of people are killed at work, and an even greater number of people suffer work related injuries because they are unable to follow safe working practices.

There are particular hazards associated with machining activities, which includes both general machining activities and the use of magnetic based equipment. Some of these hazards accompany almost all types of work activity, such as handling and slips and trips. Others, such as contact with moving machinery and contact with hazardous substances are of particular concern to machine operators as they result in significantly higher rates of injury amongst these personnel than amongst other workers. 

Manual Handling

Manual handling related activities are a major cause of occupational injury. Low back pain, joint injuries and repetitive strain injuries affect over a million people each year, and many of these injuries are the result of manual handling. Prior to carrying out any unavoidable manual handling activity, you should help to protect yourself from injury by following good manual handling practices. Consider the task to be carried out and the nature of the load, and be aware of your own capabilities and the environment in which you are working. In particular, machine attachments and work pieces can be extremely heavy and you should give consideration to safe manual handling practices before undertaking any job that involves lifting these items. 

Slips, Trips and Falls

Slips and trips represent a significant cause of work related injury. Slips and trips can result from contamination, obstacles, inappropriate footwear, reduced visibility, the environment and people’s attitudes. Good workmanship and good housekeeping are practices that can help to prevent accidents and fires. By removing debris, swarf, packaging and other waste materials to waste skips you can contribute significantly to good housekeeping. You can also reduce the risk of slips and trips by properly routing any cables or air hoses that you use, by appropriately storing materials, tools and other equipment and keeping walkways clear, by ensuring that you always wear appropriate footwear and by taking responsibility for your own and your colleagues safety and appropriately containing any spills that you might discover. 

Risk of Contact

Contact with moving or rotating machine parts is a significant hazard to personnel involved in machining activities, as well as to personnel working close by, and can result in serious injury. All personnel need appropriate training and experience to be able to use work equipment safely. Never use machinery unless you have received suitable training and are qualified and competent to do so. You should ensure that you are suitably qualified and are competent to use the particular type of equipment that you will be working on. Before you begin to use a machine, study it to make sure that you know which parts of the machine move, which parts are stationary and which parts are sharp. Make sure that all guards are in place. Remember to securely clamp both the machine and the work piece. To ensure Machine Safety make sure that you only use that piece of equipment for the job it was intended to perform. To protect others from the risk of contact with the moving or rotating machine parts, make sure that the appropriate warning signs and barriers are in place before you begin machining ensuring Authorised Personnel Only can gain access.” 

Electrical Safety

Electric shock from machinery can result in death or severe burns. Additionally, serious injury can result if the person falls as a result of the shock. To prevent the risks posed by electrical hazards, all electrical equipment should carry a valid test certificate or label. Testing should be carried out by suitably trained individuals. If an electrical appliance does not carry a test label, then please, do not use it. You should also carry out a visual pre-use inspection of all machinery, if you discover a defect or problem with the machine, it should not be used and you should inform your manager. 

Machine Malfunction

It is equally important to monitor the machine while it is running for possible signs of a malfunction. If you notice that the machine is vibrating abnormally, doesn’t sound right or is displaying signs of any other problem, switch it off and report to your manager. 

Machine Maintenance

Ensuring that equipment is appropriately cleaned and maintained is also central to machine safety. Inspect and sharpen cutting tools, lubricate machinery and check the alignment of milling machines as appropriate. Clean machinery after each use, as a dirty machine is unsafe and is difficult to use. When you are carrying out machine maintenance, make sure that you follow the appropriate lockout and tag-out procedures to ensure that the equipment is correctly isolated and cannot be turned on accidentally.

When cleaning machines after use, ensure that the machine is switched off and that the swarf has cooled before using gloves and a brush to remove swarf and clean the machine. If you need to remove swarf from a running machine, make sure that you are not wearing gloves and use a rod to remove the swarf. Never use a rag to clean a machine while it is running. Never use compressed air to clean a machine, your clothes or yourself. 

Risk of Entanglement

When conducting machining operations, it is extremely important that you take the steps necessary to reduce the risk of entanglement. Wear close fitting garments, do not wear a tie or jewelry and tie back long hair and long beards. Never wear gloves when operating a machine. If material is rough or sharp and you need to wear gloves to handle it, make sure that you place or handle the material while the machine is turned off and that you then remove your gloves before turning on or operating the machine. You should never attempt to measure a part that is moving. 

Personal Protective Equipment PPE

Personal Protective Equipment, or PPE, is an important means of reducing the risks associated with projectile particles during machining operations. At least standard PPE with safety sun glasses should be worn. It may be necessary to screen the work area if projectile particles pose a hazard to individuals working or passing nearby. Only PPE in good working condition will reduce the hazards associated with your work, so it is important to remove, clean and store your PPE correctly. 

Noise at Work

Hearing loss caused by exposure to noise at work is a significant source of occupational disease, with many people suffering deafness, tinnitus or other ear conditions as a result of exposure to excessive noise levels at work. The level of noise and how long people are exposed to noise at work both contribute to potential hearing damage. Noise can be reduced to harmless levels by using ear plugs and ear defenders while conducting machining operations, and these items of PPE should therefore be worn unless local measurements indicate that noise levels are below the level at which such action is necessary. 

Human Factors

Human factors also play a role in increasing the risk of injury while conducting machining operations. Never come to work in possession of, or under the influence of, alcohol or drugs. These substances expose everyone to risks that are unnecessary and easily avoided. You should also not conduct machining operations if you are overly tired or unwell, as concentration is important to operating machines safely. Behave sensibly in the machine shop. Don’t run and don’t walk behind someone who is operating machinery as you may bump in to them. 

Hazardous Substances

Substances such as coolants and other metal working fluids, hydraulic, lubricating, gearbox oils and cleaning agents can cause dermatitis if they come into contact with your skin. Fluid systems containing water or water mixes can cause bacterial infection on contact.

If you need to use these or other potentially hazardous substances, ensure that you follow the procedures outlined in your hazardous substance assessment, which may include the use of additional PPE. Try to avoid getting these substances on your skin, but if you do, pre-work or barrier creams will make your hands easier to clean. Rehydration creams will also replace lost skin oils after washing, and help to keep your hands in good condition. Wash, eat and drink away from your work area, and always wash your hands before eating, drinking or smoking. Avoid breathing in metal working fluid mists by using machining procedures which reduce the amount of mist produced, by using extraction and by using appropriate PPE. Remember that all hazardous chemicals can be identified by their warning signs, and should be stored in suitable containers that are clearly labelled and which identify the hazards associated with their use. Information on the substance as well as an assessment of the hazards associated with its use should also be available. 

Magnetic Based Equipment

There are additional hazards relating to the use of magnetic based equipment. It may well be unsafe to use magnetic based equipment if you have an active implantable medical device fitted. Make sure that you have informed your manager if you have an implanted medical device and talk to your doctor about the safety of using magnetic based equipment. Particular safe working practices are necessary to prevent injury should the electrical supply to the magnetic base fail. You should label the relevant electrical supply sockets and switches to prevent someone accidentally turning off the supply. 

Emergency Procedures

In the event of an emergency while conducting machining operations, isolate any machinery that you have been using and evacuate the area according to the site emergency procedures. If you are involved in an accident, seek immediate assistance. You should never operate machinery while alone unless specific lone working procedures are in place.

SAFE GRINDING OPERATIONS (GUEST POST)

1 Comment

Risk of Fire and Explosion

Grinding and allied processes produce molten metal, sparks, slag and hot work surfaces which pose a risk of fire and explosion, and which can result in fatalities, serious injury and plant damage. Flying sparks are the main cause of fire and explosion, especially as sparks can travel up to 10 metres from the work space. Sparks and molten metal can travel even greater distances when falling and can pass through and become lodged in cracks, clothing, pipe holes and other small openings. To reduce the risk of fire and explosion, a permit to work should be obtained before commencing grinding operations. Working areas and the areas below them should be kept free of combustible material. Fixed items of plant, such as installed electrical cables should be protected by a fire blanket. And sparks should be contained by means of a non-flammable material. Fire extinguishers should be close at hand, and the working area should be inspected when work is suspended to ensure there is no residual risk of fire or explosion.

Cutting Operations

Where cutting operations are performed, it is always important to give consideration to the effect that these operations will have on the stability of the work piece. In particular, consideration should be given to weight distribution, as the removal of significant weights may alter the balance of the work piece. Where appropriate, the work piece should be supported. You should also plan how items that have been removed will be lowered without risk to yourself, to others who may be working nearby, or to equipment.

Disk Burst

Serious injury can result when grinding wheels or disks burst, so it is important to take the steps necessary to reduce the risks associated with this hazard. Abrasive wheels should only be fitted by individuals who are trained and competent to do so. A pre-use check of portable grinding machines should be carried out to ensure that they are only fitted with reinforced discs, that the disc is suitable for the type of material to be ground, as well as for the speed of the machine and that guards are fitted and properly maintained. To avoid damaging discs, disc centres detaching and increased vibration levels, discs should always be applied at 90 degrees to the work piece to avoid the lateral stresses that leads to discs bursting. Uniform pressure should be applied during cutting and strategic cutting positions and / or restraints should be used where parent metal movement, which may result in snagging, is possible. All grinders have the potential to jolt when disc snagging occurs, which can result in serious injury. Where a Grinding Safety assessment indicates that snagging is a possibility, you should adopt a position that considers the direction the machine will move should snagging occur.

Training

All personnel need appropriate training and experience to be able to use work equipment safely. Never use grinding equipment unless you have received suitable training and are competent to do so, or you are receiving supervised training to reach this level of competence. Remember that contact with the grinding wheel can result in serious injury and that you should also wear protective clothing including Kevlar gloves and a visor to reduce the risk of injury.

Entanglement

When conducting grinding operations, it is also important that you wear close fitting garments. Make sure your overall sleeves are buttoned, that you do not wear a tie or jewellery and that you tie back long hair and long beards to reduce the risk of entanglement.

Personal Protective Equipment

PPE is an important means of reducing the risks associated with projectile particles during grinding operations. At least standard PPE with gauntlets, leathers, a cotton drill or fire retardant overalls and a full face visor with neck muff worn over goggles should be worn. Prolonged exposure to the dust produced during grinding operations can potentially result in scarring of the lung tissue and subsequent breathing difficulties. During prolonged or heavy operations, disposable respirators should be worn. For permanent grinders, an air fed all in one hood should be worn. Only PPE in good working condition will reduce the hazards associated with your work, so it is important to remove, clean and store your PPE correctly. All PPE should therefore be cleaned down with a soft brush before removing.

Noise at Work

Hearing loss caused by exposure to noise at work is a significant source of occupational disease, with many people suffering deafness, tinnitus or other ear conditions as a result of exposure to excessive noise levels at work. The level of noise and how long people are exposed to noise at work both contribute to potential hearing damage. Noise can be reduced to harmless levels by using ear plugs and ear defenders while conducting grinding operations and the use of hearing protection should be mandatory within high noise areas.

Hand Arm Vibration Syndrome HAVS

If you regularly use hand held grinders, you may be at risk of developing Hand Arm Vibration Syndrome or HAVS. This condition involves damage to the blood vessels, nerves and joints of the hand, wrist and arm. It is a painful and debilitating condition, resulting in numbness of the hands to the extent where it is impossible to feel with your fingers and very difficult for you to pick up small objects. This can make both occupational and leisure activities, such as playing darts, fishing or DIY, impossible. HAVS is entirely preventable. Always use the right tool for the job, as this will allow you to complete the job more quickly and will expose you to less hand-arm vibration. Carry out a pre-use inspection of all grinding equipment and report any damage to your supervisor, as faults and general wear may result in increased vibration. Try to reduce the amount of vibration you are exposed to in one go by doing other jobs in between grinding operations. Use a relaxed grip and avoid using excessive force on a tool or work piece. Store tools so that they do not have very cold handles when used next. Keep your hands warm and dry and take breaks to exercise your fingers regularly.
