SAFETY COMPLIANCE IN THE WORKPLACE: KNOWING THE RULES WHEN WORKING WITH DANGEROUS MACHINERY (GUEST POST)

 


Compliance with health and safety regulations will not only help protect you, the employer, from liability concerns but will also help keep your workers safe and machines in good working order.

The Workplace Regulations 1992 cover the majority of health and safety issues that can occur in the workplace.  These regulations are split up into three different sections: health, safety and welfare. Each of these sections is especially relevant to a workplace where dangerous machinery is used on a daily basis. 

Health 

This section relates to ensuring that your workplace isn’t set up in a way that will give your employees health issues in the short or long term.  Referring to specific key areas, here is a rundown of how the regulations apply to working with dangerous machinery:

Ventilation:

When materials are cut noxious gases or fine dust particles are often given off. This can lead to lung problems if your workers are exposed to this without adequate ventilation.   Installing mechanical ventilation will ensure that there is a supply of fresh air. Windows may provide enough ventilation, but well maintained mechanical ventilation will always be more efficient. 

Temperature:

Ambient temperature can be affected by machinery running in the workplace. If your workplace doesn’t have air conditioning then temperatures can become too uncomfortable to work in.  Temperature also refers to humidity in the workplace.  Having your workplace at an uncomfortable temperature can lead to stress and loss of concentration. This is especially relevant if your employees are working with machinery as any mistakes can lead to accidents. 

Lighting:

Your workspace should be contain adequate lighting. This is especially important for workspaces using machinery. safety precautions should also be in place incase of sudden loss of light. this means that backup systems are a must if sudden loss of light could lead to accidents.

Cleanliness:

Workspaces should be kept clear of rubbish that could pose a tripping hazard or fire risk. Provide an appropriate means of waste disposal and ensure it is removed regularly. 

Safety 

This second section deals with day to day measures that must be put into place in order to protect the wellbeing of employees. The headings that safety regulations deal with are: 

Equipment Maintenance:

Keeping your machinery well maintained will help prevent accidents that arise from faults and breakages. Likewise, keeping your devices such ventilation systems in good order will help prevent complications from arising further down the line. 

Floor Traffic:

Keeping the areas of your workplace which encounter high foot traffic clear of tripping hazards is very important. This is especially important for workers who are using machinery as a trip or fall can result in serious accidents. 

Windows:

When windows in the workplace are open, they shouldn’t pose as risk to anyone.



Welfare

The welfare aspect of health and safety compliance in the workplace relates directly to the conditions experienced by employees and maintaining their mental and physical health.  Your workplace is only as efficient as the people who are running it, and ensuring your employees are in good health will enable them to focus more and work more efficiently.   This is done by providing suitable sanitation facilities, access to clean water and regular breaks. 

By following these guidelines, your workplace will be a safer and more efficient place.

ELECTRICAL SAFETY FOR NEW ENERGY SOURCES: WHAT YOU NEED TO KNOW (GUEST POST)

The two most popular methods of powering a domestic home with renewable energy are solar panels and wind turbines. Both of these methods produce pollution, can lessen the owners reliance on the national grid and can save on energy bills.

However, they both deal with electrical currents and as a result must be installed correctly and safely to ensure they do not become a safety hazard.

In this post I am going to outline some of the typical hazards associated with domestic energy production and what you can do to prevent them.

Solar panels:

To start with, the weight of solar panels means that they are not suitable for every building. Before you even start installing them you should have your roof surveyed to make sure that it can hold the weight of the panels and the people who will be installing them.

Attaching the solar panels to the buildings electrical systems should only be done by a qualified electrician, and should include fuse set ups and grounding.

Solar panels can become extremely hot during use. This can pose a fire risk if they are installed incorrectly. There is also a risk of burns to people performing maintenance work on them, so ensure they are properly insulated.

When installing or maintaining the panel, a full risk assessment should be carried out and all standard safety procedures for working at height should be followed.

Wind turbines

Micro wind turbines are subject to all of the safety concerns associated with their larger counterparts. The stresses placed on the system during high winds can cause a lot of problems. It is important that an isolator switch be fitted to the turbine setup and that the owner know exactly where this is located.

The size of the wind turbine means that there is a risk posed by it falling over. Installations should be fitted by a trained professional and maintained regularly to lessen the risk of this happening.  

Renewable energy for domestic use is still in its infancy, but systems are improving all the time. With expert fitting and regular maintenance a method of generating clean energy in your own home can help save the environment and save you money.

This peice was written by Mark Enright a writer for http://www.enviko.com/Enviko, the renewable energy experts.

Note: As you can see, those involved in these types of work need to wear the proper protective gear, such as safety glasses, hardhats, gloves, and fall protection. pb

PREVENT WORKPLACE ACCIDENTS WITH FIRE SAFETY EQUIPMENT AND PROPER TRAINING (GUEST POST)

While the majority of workplace accident claims lead to minor injuries, fire can cause devastation. Protecting a business premises against fire will not just improve the health and safety of employees – it will also protect the general public, the emergency services and the owners of adjacent properties.

Clearwater Solicitors can help you make a workplace accident claim if you have been injured or if a loved one has lost their life as a result of a fire at work, but businesses should put all reasonably practicable steps in place to ensure fire does not harm their workforce. Businesses should have fire drills and training in place to deal with fires when they arise, and should invest in equipment to warn them of fires and help them to combat them if possible.

–          Fire training and drills

All new staff should be trained in what to do in the event of a fire as soon as they start work, and if new equipment or methods of work lead to unexpected risks, staff should be told about these hazards. Businesses should hold at least one fire drill every year and keep a record of their results.

Businesses must ensure that every escape route has a clear passageway – some accident at work claims involve slips and trips during fire drills or in actual fires. Escape routes should be direct, short, and have enough room for everyone to get through, and staff should be provided with a safe meeting point.

Ensuring escape routes are safe could require the use of emergency lighting and emergency doors, and businesses will have to consider which solutions are right for them. Companies are also obliged to make special provisions for wheelchair users and other people with mobility problems – this could involve selecting people to help wheelchair users get downstairs if there is a fire.

–          Fire equipment

Companies can significantly reduce their likelihood of facing accident at work compensation claims by investing in fire detection equipment, The type of equipment suitable for a particular business and the location of this equipment will depend on a variety of factors, but warning systems and detection systems will be essential.

Fire fighting equipment is also recommended, however, the correct equipment for each individual company will depend on the type of business it is and the building it is in. Staff should be trained in how to use this equipment when necessary.

All fire detection, prevention, warning and fighting equipment must be properly installed, well maintained and regularly tested.

Importance of fire safety

Every business must ensure its fire safety procedures are effective and suitable for their particular requirements, and must regularly assess and update these procedures to deal with emerging risks or new employees. When businesses fail to protect the wellbeing of their workforce effectively, they can find themselves facing accident at work compensation claims, or being prosecuted in court due to health and safety regulation breaches.

If you are unsure about the fire safety procedures in your business, then speak to an expert consultant before it is too late.

TOP SAFETY TIPS WHEN WORKING WITH GLASS (GUEST POST)

Working with glass can be hazardous, but there are several safety tips you can follow to protect yourself and others from injuries. If you don’t take the proper precautions, you may face lacerations, punctures and cuts to your eyes, skin and even tendons and arteries. Working with glass is nothing to mess around with, but you can know that you are safer in the workplace by remembering the following safety tips by heart every time you work with glass.

Wear Eye Protection

Wearing proper eye protection is essential any time you enter a workspace where you or machinery handle glass. Be sure to always wear good quality goggles or safety glasses whenever you are cutting or grinding glass and spend a few extra pounds (dollars) on a high quality pair of goggles or safety glasses to provide protection for all areas of your eyes.

Wear Ear Plugs

Protect your sensitive ears by wearing ear plugs when working around loud noises. These will protect your sensitive ear drums and also prevent shards of glass from entering your ear canal and causing serious damage to your inner ear.

Handle Glass Breakage Correctly

Always use a dustpan and brush or another approved method of collecting broken glass. Never use your bare hands or materials such as sponges, napkins or towels to pick up broken glass as tiny glass particles can get stuck in them. It’s also important to post a warning sign in the area of the glass breakage to alert others about the potential danger.

Wear Closed-toe Shoes

The best way to protect your feet against damage from glass is to wear closed-toe shoes that completely cover your feet. Never wear sandals or other open-toe shoes whilst working.

Keep covered up

Keep the rest of your skin protected by wearing long sleeves. Tank tops and shorts are not proper attire for a glass workspace. Broken glass can cut the skin on your arms and legs, and dangerous chemicals and solder can burn and damage your skin.

Keep Long Hair Secured

If you have long hair, always ensure it is tied up into a ponytail or otherwise secured. Bending over and getting your hair caught in a glass grinder can be very painful. A hat or protective hair net is also helpful for those with shorter hair too.

Don’t Smoke or Eat Around Glass

Never smoke or bring your food around your glass workspace. You may be handling chemicals that can be easily transferred to your cigarettes or food. If tiny glass particles end up in something you are about to put to your mouth, they can cause serious internal damage to your body.

Keep a Well-stocked First Aid Kit

It is important to have a well-stocked first aid kit nearby and to know where it is and how to use all of the items in the kit. A well-stocked first aid kit should include bandages, burn ointment, alcohol, scissors, antiseptic wipes and gloves. Ideally, a glass workplace will also include an eyewash station.

Wear Protective Gloves

You should wear thick protective gloves whenever you have a piece of glass in your hand. Be sure that the gloves have a cuff and that they are at least as thick as a typical pair of gardening gloves.

Keep Untrained People Out of Workspace

Even if you know how to protect yourself when working with glass, injuries can still occur if untrained people enter the glass workspace. They can touch things they shouldn’t, which can cause serious injuries to both themselves and to you.

You do not need to panic when working with glass, but it is essential that you follow these safety tips to prevent injuries to yourself and others in the workspace.

STEPS TO STAY SAFE IN THE WORKPLACE (GUEST POST)

We all have the right to feel safe and secure in our workplace, whatever line of work you are in. Although all employers are legally obliged to take precautions to minimize health and safety risks in the workplace, we also need to take personal responsibility for our own safety.

The good news is that you don’t need to wrap yourself in bubble wrap and constantly wear a crash helmet to keep yourself safe, it is mainly basic common sense. These are a few tips to help you protect yourself whilst at work-

  • Communication is vital, not just for your safety, but your colleagues and customers as well. If you notice that equipment is getting worn or something looks faulty, notify your supervisor or health and safety representative as soon as possible.
  • Familiarize yourself with your company’s health and safety procedures. Every employer needs to conduct a risk assessment which will include ways to avoid hazards and the correct, safe way of performing tasks to avoid injury. You should also be made aware of the location of emergency exits, evacuation assembly points and first aid boxes as part of your orientation.
  • If you ever out on the road as part of your job or spend time working alone, consider downloading a personal safety application on to your smart phone, such as the personal safety app from Lookout Call. These have features that ensure that you get a speedy response if you are in danger and to locate you if you break down in the middle of nowhere.
  • When you are in a profession where you have to enter stranger’s premise, for example if you are an electrician or plumber, you can sometimes get a bad vibe straight away. Always trust your gut instinct and arrange for somebody to call you so that you have an excuse to leave if you feel unsafe. If this isn’t a viable option, try to get a personal safety app for your phone with features that autodial for you or that will raise an alarm if you don’t respond to a prescheduled call.
  • Don’t use any machinery or perform any tasks that you have not been trained to do. If you have been trained but can’t remember the correct or safest way to do it, don’t be nervous of asking your supervisor or trainer for some refresher training.
  • It may sound very basic, but ask anybody entering your premises, such as delivery or repair persons for ID. If you work in a space by yourself, for example in a petrol station or cleaning in the evening, try not to let anybody in that you are not expecting.
  • When you have to travel for work, make sure that somebody knows where you’re going and what time you are expected to be there so you can arrange ‘check in’ calls.
  • If you work with hazardous chemicals always read the bottle and act on any safety precautions the manufacturer’s advice, such as the use of gloves and ensuring you have ventilation.

It is very easy to keep safe at work as long as you maintain good communication with your employers and colleagues and don’t take unnecessary risks.

THE TEN MOST COMMON INJURIES SUFFERED AT WORK (GUEST POST)

Every day we go to work and assume that we will return home safely again at the end of the day.  Unfortunately this isn’t always the case.

Many people are seriously injured and sometimes killed at work, doing the job they are paid to do. Sometimes this is due to accidents and sometimes it can be due to negligence or lack of care.  Here are some of the most popular types of injury in the work place over recent years.

Overexertion Injuries

Physical activity such as pulling, lifting, pushing, holding, carrying, and throwing can all take their toll. Overexertion is ranked annually as one of the most common forms of workplace injury and account for millions in benefit costs every year.

Slips and Trips

Slips and trips can happen anywhere, but in the workplace the problem is more acute. Wet and slippery floors or objects left lying around can all contribute, but it is often up to the employer to ensure that spills are promptly cleaned and no debris is present which can be dangerous.

Collisions

This happens when a person accidentally collides with an object such as a wall, door, cabinet, windows, table, chair etc, resulting in an impact injury. An employee’s diligence and the employer keeping the work environment free from hazards are key to preventing these types of injuries, which account for thousands of lost hours per year.

Falls

Falls from an elevated area such as roofs, ladders, and stairways can cause serious injury and are very common in work environments such as factories and warehouses.  They can be caused by slips and falls or due to faulty equipment.  These types of accidents can be reduced by the use of proper personal protection gear, training and employee diligence.

Vehicle Accidents

Employees who drive for a living, such as taxi and bus drivers, are always at risk of being involved in an accident due to the amount of time they spend on the road. They are still entitled to as much protection as anyone else however, as they are technically in their place of work. Also, people using equipment such as forklift trucks and cranes can also be injured or even killed if not given the correct tuition.

Machine accidents

Usually occurring in a factory environment, where heavy equipment and machinery are used, clothing, shoes, fingers and hair can easily be trapped or caught; leading to serious injuries. The appropriate personal protective equipment and training should always be provided.  Leave the jewelry at home, and if you have long hair, tie it up.

Acts of violence

As bizarre as it sounds, attacks and other arguments can lead to serious physical injuries. Workplace violence, employee training and employee diligence can help keep these incidents at bay. As well as employee-on-employee violence, customer violence towards staff often contributes towards workplace injuries, a matter which many companies are taking more and more seriously.

Falling objects

Head injuries are often caused by falling objects, whether it’s from shelving, scaffolding or ladders. Employee diligence and employer focus are key to preventing these types of injuries from happening regularly. PPE such as hard hats can be instrumental in keeping incidents like this to a minimum.

Hearing loss

Constant exposure to loud noise can result in significantly reduced hearing. The effect can be subtle and gradual. Basic safety measures such as ear protection and ambient noise barriers can eliminate this injury from any workplace.

Burns

Burns are often caused by chemicals used in industrial settings such as labs or factories. They can also be inflicted by equipment that has become overheated; welding torches, irons and even a kitchen kettle. Clearly visible warning signs can go a long way to prevent such injuries occurring.

WORKING IN CONFINED SPACES ISN’T FOR EVERYONE!

The thought of working in a small, enclosed space makes me gasp for air!  Certain people feel smothered in situations when their work involves being placed in a closed or partially closed space.  Confined spaces should be made safe for the worker by taking the proper precautions to ensure that it is secure.  Those with claustrophobia can’t help this feeling, and should seek other jobs. 

There are many regulations that deal with confined space entry.  A Confined Space Hazard Assessment and Control Program must be conducted prior to the beginning of work.  Confined spaces can be more hazardous than other workspaces for several reasons.  Workers are killed and injured each year while working in confined spaces, and an estimated sixty per cent of the fatalities have been among rescue workers.  

Let’s review some of the places that people must work that are considered confined spaces:

  • Open ditches; (possibility of collapse);
  • Silos
  • Manholes
  • Wells
  • Tunnels
  • Cold storage units
  • Tanks
  • Culverts
  • Vaults
  • Rail tank cars
  • Caves
  • Underground mining
  • Sewers
  • Pipes
  • Boilers

Reasons for these  being considered confined spaces are that they have a restricted entrance or exit by way of location, size or means.  Also, they are not originally designed for human occupancy.  Places such as this can indicate a risk for the health and safety of anyone who enters, due to the materials and substances in it (bad air), and the way it is designed.  Other hazards include fire hazards, noise, temperature extremes, uncontrolled energy, barrier failure and visibility.  All potentially hazardous energy sources: electrical, hydraulic, pneumatic, mechanical, chemical must be de-energized and locked out prior to entry to the confined space, preventing accidentally turning on power sources. Ventilation is of the utmost importance while working in these conditions.  Natural ventilation is not reliable and insufficient to maintain the air quality.  It is usually necessary to maintain air quality through mechanical ventilation (fans, blowers).  While workers are inside confined spaces, there should be someone standing close by that is prepared to get them out, in case of an emergency.  This plan of action should be in place prior to entering the space, and communication between the inside and outside should be constant.  

Confined space hazards are mainly controlled through traditional methods, such as engineering controls, administrative controls, and personal protective equipment.  Special precautions not usually required in a regular worksite may need to be taken.  Mechanical ventilation is the engineering control regularly used.  Entry Permit system is a type of administrative control, and personal protective equipment (respirators, ear plugs, hardhats, and gloves) is commonly used in confined spaces as well. 

It is the responsibility of the employer to ensure their workers are safe while working under these conditions.  If the worker feels proper precautions were not taken, they should not enter until it is made safe by additional means.

SAFETY TIPS EVERY TRADESMAN SHOULD KNOW WHEN WORKING WITH ELECTRICITY (GUEST POST)

 

As many of you may know, working with electricity does have its risks and tradesmen working with the hidden dangers of household and industrial electricity on a daily basis should be on their guard, exercising safety and caution at every turn. According to a recent survey by Electrical Safety Foundation International (ESFI) in the past decade 46,000 workers have been injured on the job by industrial electrical hazards, but what can you do to ensure you don’t form part of this statistic?

Check out the following four safety tips for industrial professionals to ensure they get through their working day safely and without encountering all-too-common hazards and resulting electricity-related accidents…

Never Assume Safety

Forgetting the basics of electrical safety, whether working with industrial alkaline batteries on a small installation or live conductors at a large scale manufacturing plant, results in the majority of injuries, such as electrocution, electric shocks, burns and falls. Never assume that an electrical component you are handling is safe, always run the necessary checks to ensure that the component you are working with is free from hazards before starting your project.

Know the Warning Signs

The second part of the ‘never assume safety’ rule is knowing how to confidently determine the warning signs and dangers that come with electricity and electrical components. If you are unsure about how to identify these hazards, then get clued up before you take on the project with professional training and assistance from a more qualified industry expert. After all, even if you have experience working with household voltages, this does not mean that you can work safely with commercial or industrial application voltages.

Use the Right Safety Equipment

As well as using your industry knowledge to identify the warning signs of electrical safety, it is also necessary to know what type of safety equipment is appropriate when dealing with electrical faults, devices, panels and other equipment to avoid serious injury. Always wear the appropriate safety gear; safety glasses, ear protectors, gloves, dust masks and rubber soled shoes are all essential accessories for completing an electrical project.

Test, Test and Test Again

Testing all electrical components before you start work is also an important step in electrical safety and testing should be completed thoroughly before checking whether a device is even on or off, or industrial batteries are energised. A non-contact voltage tester is every electrician’s best friend so make it yours; this handy tester can pinpoint whether a circuit is on before you even touch the switch or remove the panel to view its internal wires. Keep up to date with the latest electrical safety equipment and see the risk of electrical injury diminish!

MORE SAFETY SUGGESTIONS FOR SUMMER WORK

During the summer months, the right type of training and adequate protection can go a long way toward keeping workers safe outside, where workers are exposed to heat stress and UV radiation, pest-borne diseases, and poisonous plants .

Timing can be everything. While you can’t always choose your hours or work locations, you may be able to plan your workload to avoid overheating. Schedule your heaviest work for the coolest parts of the day. In the summer, sunlight exposure is greatest between 10 am and 4 pm.   Many workers start their day very early in the morning, and quit before the hottest time of the day starts, or return to work in the evening hours.  If you are working between 10 am and 4 pm, take several breaks during those hours, in a shady place.  

Stay hydrated.  When it’s hot, you must remember to drink enough fluids. Drink before you get thirsty, because once you become thirsty, you are already beginning to dehydrate. Skip drinks with caffeine, alcohol, and large amounts of sugar. Water is still the best choice, but if you are sweating a lot, drink a sports beverage to help replenish your electrolytes and prevent heat cramps.

 Summer fashion advice:  Wide-brimmed hats, sun glasses with side panels, and pants tucked into socks may not make much of an impression, but they can prevent any number of burns, stings, and bites. Full-length pants and long-sleeved shirts reduce bites from mosquitoes and ticks and minimize skin contact with poisonous plants. Hats and safety sunglasses protect your skin and eyes from the sun’s UV radiation. If you have a history of skin cancer, you may choose dark clothing with a tight weave, which blocks UV rays more effectively than light-colored, loosely woven clothing. However, if pests are more of a concern, wear light colors and tuck your pant legs into your socks to avoid unpleasant up-the-leg visitors. To stay cooler in the heat, wear light-colored clothing that is loose-fitting and made from a breathable material such as cotton.

Know your plants. Poison oak, ivy, and sumac are found throughout the United States. The sap oil from these plants can cause painful allergic reactions. Investigate the types that are poisonous, and avoid them. Wear long sleeves, long pants, boots, and gloves to shield your skin from contact. Also, you may consider using a barrier skin cream.  Burning plants that may be poison ivy, poison oak, or poison sumac can cause life-threatening allergic reactions from the smoke. 

Find out if any workers have existing allergies.  In addition to knowing first aid and having first aid kits handy,  supervisors should be aware if a worker  is allergic to certain insect bites or stings, plants, etc., and be prepared to treat them as soon as possible.  The worker should carry benadryl, or some type of allergy medicine to avoid going into anaphylactic shock.

Watch out for the critters!  Tall grass, leaf litter, rocks, wood piles, and bushes are favorite hiding places for spiders, ticks, scorpions, and snakes. If possible, stay away from these areas. Wear gloves when handling brush or debris. Wear boots, pants, and long sleeves when working in tall grass or underbrush. Cut grass and remove dried leaves from around the worksite to reduce tick populations. Be cautious near piles of undisturbed materials where snakes or spiders may be. Store unused apparel and equipment in tightly closed plastic bags. An additional spider caution: they are often found living in outdoor toilets where flies are plentiful.  If you are working around standing water, or where mosquitoes breed and live, be aware that some of these little pests carry West Nile Virus.  This is a very serious and debilitating disease, so be sure you have insect repellent sprayed all over your clothes and open skin.

Monitor your coworkers. In addition to your own physical condition,  also keep an eye on your coworkers. Learn the symptoms of heat-related illness, and watch for them in yourself and others. Understand that protective clothing or personal protective equipment may increase the risk of heat stress. Also, brush up on your first aid so you can help a coworker who may need immediate help if suffering from heat stroke or other heat-related reactions.  Observe certain workers, such as older ones, that could be prone to heat stroke.  Those with heart disease or other health problems may not be able to stand continuous heat very long.  You and your coworkers can also help each other by inspecting for hard-to-spot creatures. Ticks, in particular, can be difficult to see, especially on your own body. Help each other inspect skin, hair, and clothes for unwanted passengers.

Use plenty of  sunscreen.  Last, but certainly not least,  follow this advice: wear plenty of  good sunscreen to block UVA and UVB radiation. Wear sunscreen with a minimum of SPF 15. SPF refers to the amount of time you will be protected from a burn. An SPF of 15 will allow a person to stay out in the sun 15 times longer than they normally would be able to stay without burning. The SPF rating applies to skin reddening and protection against UVB exposure. It does not indicate any level of protection against UVA. A good broad spectrum sunscreen will contain additional ingredients to block UVA.  Ask your dermatologist what he/she recommends.  Sunscreen performance is affected by wind, humidity, perspiration, and proper application. It should be reapplied at least every two hours. Some sunscreens lose their efficiency when used with insect repellent.  Throw away sunscreen bottles that are more than 2 years old, as it is no longer effective.
