RISKS AND REWARDS OF BEING A PLUMBER (GUEST POST)

Work safety has always been a top priority in the plumbing and heating industry. As plumbing is a profession that involves frequent exposure to hazardous situations and chemicals. Plumbing experts needs to be precise with regard to their health and work standards. Plumbing as a craft requires significant technical knowledge and involves much more than simply unclogging a sink or replacing a home shower. 

Typically, a plumber’s work involves working with a wide variety of plumbing tools and equipment in different challenging situations on a daily basis. It is therefore vital that all plumbing engineers are well aware of the risks involved in the occupation and are able to take the appropriate safety measures to minimize them. 

Professional plumbing experts like Plumbers 4U ensure that all their staff are trained and well versed in their own health and safety policies and adhere to safe working practices onsite. These emergency plumbers, working in the North London area and serving Camden, St. Albans, Enfield, Barnet and Brent, work to ensure that all projects are delivered in a professional, responsible and safe manner. 

 There are many well-known risks involved when working as plumber – but taking the correct precautions and safety measures will ensure safety and success in the field. 

  • Plumbers often need to work in close proximity to flammable or combustible substances, and risk exposure to toxic substances like lead, asbestos, adhesives, solvents, solder and sulphur dioxide
    Take proper precautions to avoid inhaling harmful vapours by using properly fitted respirators and ventilation systems, and use eye protection while working with chemicals and in areas where foreign materials may enter your eyes. 
  • There is an increased risk of injury while working with different tools
    Keep your equipment and tools organized and work in a clutter-free area. Inspect the different equipment for safety hazards before each use. All bench and hand grinders should be checked prior to use and should have the proper safety guards in place. 
  • Working in different awkward positions, and lifting heavy or awkward objects could cause back injury
    Work in a clutter-free area and work with your back hunched as little as possible. If lifting heavy objects, bend at the knee and keep a straight back, and do not try to lift something that’s too heavy. 
  • Exposure to extreme temperatures might lead to burns from steam or hot water
    Secure cut off valves prior to working with steam lines or hot water lines. 
  • Plumbers risk electrocution by working with electrical equipment in close proximity to water
    Do not work with electrical equipment while in water or if the equipment is wet, and inspect all electrical cords and plugs for exposed wires or cracks in the insulation before each use. 
  • There is a risk of slipping, tripping or falling on wet surfaces especially while working at heights
    Ensure that you use fall protection and that you take extra care while working at heights.  

Although challenging, there are a lot of benefits to a career in plumbing. You’ll be able to start your own business and set your own work timings, and can therefore set different appointments to fit your work schedule. You’ll never be short of work – plumbing is not an industry that can ever go out of fashion, nor can the need for plumbers ever dwindle. The profession also ensures a fairly good income, as you’ll be able to charge for your skills on an hourly basis. 

Sent to us by Ram Seth, writing for Plumbing specialists Plumbers 4 U ensure that all of their engineers adhere to the industry’s safety standards to avoid or mitigate some of the above risks, and as long as an accident-free plumbing workplace is maintained, which requires a commitment from everyone within a company, the profession of plumbing is a lucrative one.

We appreciate these safety tips, and all understand that plumbers do many jobs that none of us want to do. They know what they are doing, and are worth the charge. pb

PORTABLE APPLIANCE SAFETY TIPS FOR PARENTS AND CHILDREN (GUEST POST)

Portable Appliances and Children – Tips to Ensure Safety 

What on earth would we ever do without our beloved household appliances? We depend on various electronic implements in every room of the house to help sustain our comfort, nourishment, health and beauty. While many appliances stay put year round, several others are transferred from room to room, as they’re needed. And this portability certainly provides substantial convenience in today’s modern homes, but with it comes a greater amount of risk—especially in households with young children. 

Kids of all ages are notoriously curious beings who frequently explore and test the boundaries of their environment by touching, grabbing, twisting, pulling and pushing almost anything within reach (just ask any parent). Because of this natural trait, children are vulnerable to the potential dangers associated with some of the following commonplace portable appliances: 

·         Climate control – fans, space heaters, humidifiers

·         Cleaning and maintenance – vacuums, irons, sewing machines

·         Health and nourishment – air purifiers, water coolers 

And some of the risk factors that accompany these appliances include: 

·         Flow of electricity

·         Temperature sensitivity

·         Sharp components

·         Sheer weight of the appliance 

While potential dangers to children do exist, parents don’t necessarily have to sacrifice owning and using portable appliances, especially since they rely on many of them to help care for their kids. Below are some safety tips that, when followed, allow children and portable appliances to coexist safely under one roof. 

1.      Place portable appliances on stable, level surfaces and out of a child’s reach, if possible. If a portable appliance, like a window air conditioner or a microwave oven, becomes a semi-permanent fixture, ensure it’s securely installed and regularly inspect the condition of its stability.

2.      Keep all electrical units and cords away from high-traffic areas where children can easily bump into or trip over them.

3.      Practice the utmost care for all power cords to avoid a child’s contact with electricity:

a.      Ensure cords and plugs are in good condition, without any exposed or frayed wires, or bent/broken prongs—replace as needed

b.      Do not run cords under rugs or carpets—concealed damage often remains unrepaired, which increases the risk of a child encountering a hazard

c.       Be sure all plugs are fully inserted into wall sockets at all times

d.      Unless it’s absolutely necessary, do not connect portable appliance power cords to extension cords—fewer places of potential exposure to electricity means fewer chances children will come into contact with it

4.      Position all portable appliances and power cords a safe distance away from water sources—and if an appliance contains water, such as a humidifier or water cooler, be sure there is no chance the water can spill onto the power source. Always unplug the unit when transferring water to or from it.

5.      Maintain at least three feet distance between any flammable materials and hot-to-the-touch appliances, such as space heaters and irons. Be extra watchful for your child’s toys and blankets.

6.      As often as humanly possible, do not leave your child alone in a room with a portable appliance, unless it’s securely located out of reach. 

Portable appliances are vastly safe for use in most households, but they can prove dangerous when in use around unattended children. If parents teach their kids simple rules right away, and perform essential safety measures, children can explore the curiosities of their home safely, and every household member can stay comfortable, nourished, healthy and beautiful. 

What are some other safety tips you’re willing to share?   How have you adapted the placement and usage of your portable appliances to ensure your young ones are safe from the threat of harm?  Please send your comments to pat@tasco-safety.com, and we will feature an article with your tips. 

 

 
Thank you, James, for this informative article.  To start off on the comments, I would say that curling irons left plugged in are very tempting to little hands. Hope we hear from some others who will add to our list. Pat
 

MORE ELECTRICAL SAFETY IN THE WORKPLACE TIPS (GUEST POST)

 We all use electricity on a daily basis; it’s become a necessary part of everyday life. However we must remember the dangers of electricity as it can kill or severely injure a person or cause damage to properties. This could be from contact with an electrical current causing shock or burns, faults which could cause a fire or an explosion where electricity could be the source. Electrical hazards are estimated to cause around 300 deaths and 4000 injuries in US workplaces each year. It should not be forgotten about or underestimated. 

Electrical safety in the workplace is vital as we use electricity in in every job we do, from typing on our computers to boiling the kettle. It is something that all business owners and managers should be conscious of and in order to reduce the risk of accidents with electricity, it’s important to take some precautions. 

Electrical equipment should be tested on a regular basis. This could be checking them yourself or using PAT testing services, which is completed through visual checks and electronic tests to ensure safety is maintained. If you already suspect that something is faulty then take it out of use as soon as possible to prevent any hazards. 

Where equipment is being used every day, this is most important. Computers and tills are used in the workplace constantly and therefore pose a safety threat if not maintained. Kettles, ovens and food processors are used in cafes and restaurants but also in offices. As they are used so frequently in these environments, appliances need to be fit for use. A switch could be provided near each piece of equipment in order to cut off power in an emergency. When in a factory, electricity is heavily relied on and can be the most dangerous if anything goes wrong. The right safety measures need to be in place so this does not happen. 

Signs should be present to alert workers to electricity dangers. Low voltage cables are still hazardous and should be clearly marked to avoid anyone touching them. 

Employees need to have proper training to ensure that they can carry out tasks safely. Accidents can always potentially happen, but as an employer you need to keep your workers as safe as possible, otherwise if anything was to happen then legal action could be taken. If you are a business owner then it is your responsibility to make sure your employees are working in a safe environment, ultimately this should be paramount to your company policy.

The correct PPE should be furnished by the employer, protective gear that meets the needs of the workers.  Dielectric glasses, proper gloves, and hardhats that do not conduct electricity should be worn.

ELECTRICAL SAFETY – ALL YOU NEED TO KNOW (GUEST POST)

By Grace Beckett 

Electricity is almost everywhere. It is never good to come in contact with it, as it always looks for a way to reach the ground. If you are in its way, it will most definitely pass through you. It is better to take precautions than to face a fatal situation. Here is all that you need to know about making your your environment electricity-proof. 

In your yard 

  • Make sure your house is not built adjacent to any transformer. Always have a front yard and backyard to give your house some distance from the power lines.
  • Keep all the tools in a safe area like a garden shed or a garage far away from any electric lines.
  • Position all the satellite dishes, television and radio antennae in an area on the roof where there would be no interference with any power line.
  • While using metal ladders, make sure you work away from any overhead lines. If you work on an aluminium ladder that is in contact with a power line, you might get electrocuted. Use wooden ladders if possible.
  • Do not attempt to rescue objects or animals from power lines on your own. Call for help from the electricity department or the fire department.
  • Trees can conduct electricity when in contact with any power line. So remember not to climb trees close to transformers or power lines and educate your kids on this.
  • While landscaping, make sure that your trees, plants and shrubs do not interfere with power lines and transformers.
  • Electrical circuits and outlets that are present outdoors need to be protected with a Ground Fault Circuit Interrupter (GFCI). 

Within your walls 

Keep testing all your electric outlets and appliances for any damage or break. Replace defective electrical parts when necessary. Install all electrical outlets higher up on the wall away from a child’s reach. Another reason for this is because outlets closer to the ground may cause dangers if there are water spills near the electrical circuit. Keep all electrical appliances away from water. Make sure there are no hair-styling equipments like blow dryers, straighteners, dehumidifiers, etc., in your bathrooms or near the kitchen sink. 

Water is an excellent conductor of electricity, so keep away all electric cords from damp places. Avoid overloading any electrical outlet. Keeping checking all the circuits and wiring for any defects and get them fixed immediately. Always switch off an outlet before unplugging the cord. Unplug unused electrical appliances and keep them in a safe place till you need to use them again. Do not keep any electrical appliance or cord on any cloth like curtains, carpets, table cloth, etc. All electrical appliances release heat and this may sometimes lead to a fire. Use tested and certified appliances and electrical equipment (Ex: Underwriter Laboratories certified.)

EDUCATE YOUR KIDS ON ELECTRICAL SAFETY (GUEST POST)

Another great article sent to us by Grace Beckett.

Educate Your Kids on Electrical Safety

It is important that you keep your family and home safe from the danger that electrical appliances pose. Electrical safety must be observed each time you touch an appliance connected to electrical circuits. Even bad weather conditions, hurricanes, floods, tornadoes and ice storms can pose a great risk to your electrical safety. Apart from you being careful, you have to ensure that you educate your child on electrical safety. Electricity surrounds your children everyday as they work on computers, encounter cords, appliances, power lines and outlets. 

When it comes to your kids, it is important that you teach them safety skills that they can use to make informed decisions when they are around electricity. Make sure that you teach your child how to avoid injuries due to electricity. Here are few things regarding electricity, which you should educate your kids about. 

Electricity follows the simplest route through the ground 

Inform your kid that electricity always tries and gets to the ground. Electricity takes a shortcut whenever possible. So, if some material like iron provides an easy path for electricity to travel, it will definitely take it! 

Electricity and the body 

It is important that you inform your child that metal and water are the best conductors of electricity. Mention that the water in our bodies makes us good conductors of electricity. Make your child understand that if he touches the ground and any electrical circuit simultaneously, he will become the carrier of electricity. Tell your children that electricity can easily flow through them and can hurt or kill them. 

Your children should know that they need not touch the ground directly to experience a shock or conduct electricity. Even when they touch a faulty electrical appliance while holding on to a bad conductor of electricity, like wood or tree, they can get an electrical shock.  

When your child is standing in water or touching an electrical appliance with wet hands, he or she can experience shocks, as electricity can rapidly travel through water. This is the main reason why you have to keep away all the electrical appliances from water. Ensure that you tell your child not to touch any electrical appliance when his or her hand is wet. Standing in a wet and marshy area touching electrical appliances can be very dangerous. 

Electricity and appliances 

Most of the electrical appliances have insulated coverings and cords to avoid electric shocks. Whenever your child is using an electrical appliance, ensure that he or she keeps the coverings and the cords in position to avoid electric shocks. If you find that the insulation for a particular appliance is not intact, tell your child not to touch that appliance until it is fixed. 

What should your child know about electric shocks?  

Nobody can tell when the contact with electricity can be fatal; so let your child know that electric shocks can cause weakness, spasms, shallow breathing, severe burns, rapid pulse, unconsciousness or even death. So, make sure that your child is very careful when he or she is dealing with electrical appliances.

GET YOUR ARC FLASH GAME ON! (Guest Post)

Get Your Arc Flash Game On

By Jack Rubinger, jarubinger@graphicproducts.com, www.DuraLabel.com

What happens when an arc flash occurs? And what is being done to lessen the risk? Few topics stir the emotions as much as arc flash dangers.  There is so much energy involved, and the nature of electricity is unlike anything else: invisible and unpredictable. Think burns and severe eye injuries.  

Working smart is critically important though experts agree it’s still hard to anticipate an arc flash occurrence. That’s why it’s so important to be prepared.  The most important question is: “Can we do this work de-energized?” said Mike Balinskas of PowerHawke, Inc. 

“Unfortunately, arc flash studies aren’t an exact science. They are snapshots, based on current utility information. As the grid fluctuates over time, so does the hazard exposure,” said Dave Hill, Intertek Testing. So it’s not enough to rely on PPE. Every precaution should be taken to prevent arc flash.

What’s missing from many electrical safety programs is a strategic game plan to address arc flash hazards.

“The distance between a lifetime of pain, disfiguration, and disability when compared to going home safely is no further than the fraction of an inch air gap that can be ionized to initiate an arc in the presence of significant voltage. Knowing the site and following the rules keep individuals safe and equipment intact,” said Michael Morse, Professor of Electrical Engineering, University of San Diego.

Electrical safety plans must address:

  •         Training/compliance
  •          PPE
  •          Tools/equipment

Training/compliance

Employees fear they’ve not been adequately trained. Training needs to increase to keep employees up to speed. How familiar are you with new NFPA requirements and how they apply to your equipment?

Mr. Hill reviews current arc flash NFPA, ANSI, IEEE and NEC information:

  • NFPA 70-2011/NEC is the driving document for all electrical installations. The other NFPA, ANSI/UL, IEEE, NEMA and harmonized IEC documents refer back to the NEC for installation practices.
  • NFPA 70-2011/NEC Section 110.16 and the Informational Note reference NFPA 70E for guidance of Arc Flash and PPE as well as ANSI Z535.4 for the safety warning signage.
  • Industrial electrical equipment and control panels, are required by NFPA 70-2011/NEC Section 670.3(A) to have a permanent label denoting short-circuit current rating of the control panel with references to UL 508A Supplement SB as an example of determining the SCCR. Section 409.22 and 409.110(4) are the references for industrial control panels specifically.
  • NFPA code calls for labeling electrical panels, disconnects and access points to inform those servicing equipment to communicate potential arc flash hazards present based on studies of the electrical system feeding each location.
  • NFPA 70E requires workers to document arc flash analysis calculations used for electrical equipment labeling. Even though NFPA 70E and IEEE 1584 provide standardized calculations for an arc flash analysis, other methods exist, opening the door for variation. Posting key elements of your analysis on electrical equipment will help you remember the methods used after a job is complete.

As of September 30, 2011 NFPA requires labels to display the nominal system voltage, arc flash boundary and one of the following: 

  • Available incident energy and the corresponding working distance
  • Minimum arc rating of clothing
  • Required level of PPE
  • Highest hazard/risk category (HRC) for the equipment 

NFPA’s new standards require that labels display additional information and must be posted on switchboards, panelboards, industrial control panels, meter socket enclosures and motor control centers.

A switchboard is a large single panel, frame, or assembly of panels. Switches, overcurrent, other protective devices, buses and usually instruments are mounted on the face, back or both. Switchboards are generally accessible from the rear and from the front and not intended to be installed in cabinets.

Panelboards are single panels or groups of panel units designed for assembly in the form of a single panel. These include buses, automatic overcurrent devices and those devices equipped with or without switches for the control of light, heat or power circuits. Panelboards are designed to be placed in a cabinet or cutout box or against a wall, partition, or other support; and accessible only from the front.

There are two main types of industrial control panels (ICP) — enclosed and open ICPs. Enclosed ICPs are installed within a complete enclosure at the panel manufacturer’s location. An open ICP includes factory wiring, field wiring terminals and components mounted on a sub-panel without a complete enclosure. ICPs often contain motor controllers, switches, relays, power supplies, computers, cathode ray tubes, transducers and auxiliary devices used in the manufacturing process to control industrial utilization equipment.

Meter socket enclosures are equipped with matching jaws to accommodate the bayonet-type (blade) terminals of a detachable watt-hour meter. It also has a means of connections for the termination of the circuit conductors. It may be a single-position socket for one meter or a multi-position trough socket for two or more meters.

Motor control centers are unlike other types of power distribution equipment, which are used with a variety of load types. Motor control centers primarily control the distribution of power to electric motors.

PPE 

Whether you are in an underground high-voltage transmission system or a substation, personal protective equipment (PPE) reduces exposure hazards. PPE means wearable protective gear: a shielded hood, bibs or coveralls. 

“A key technology ensuring safety is the infrared window. Installed on cabinet panels and doors, IR windows are view ports providing access into electrical cabinets and other enclosures. With an IR window, an electrical worker uses an infrared camera to inspect energized internal electrical components for temperature abnormalities without the direct exposure from removing covers and panels,” said Andre´ Rebelo, FLIR Systems, Inc. 

Infrared windows are a framed lens made of special transparent crystal or polymer material allowing infrared spectrum waves to pass through the window making it easy to perform infrared inspections. IR windows have a protective cover to shield the lens when not in use. 

Tools and Equipment


Industrial labeling systems such as the DuraLabel Toro are indispensable for electrical contractors. New systems are mobile, compatible with many types of software and empower end-users to quickly create custom safety, hazard and warning signs and labels on-site, in sequence. Displaying arc flash calculations on an industrial label offers valuable information to other electrical workers, inspectors and emergency responders who will likely work on or around the equipment you label in the future.  

No one can dispute the power and force of an arc flash. Following these three strategic steps, we can minimize many arc flash hazards.

MAY IS NATIONAL ELECTRIC SAFETY MONTH

The theme of this year’s National Electrical Safety Month is “Be in the Know about the New.”  Sponsored by the Electrical Safety Foundation (ESFI), a non-profit organization dedicated exclusively to promoting electrical safety in the home, school, and workplace.  This month’s observance is to increase public awareness of electrical hazards in order to reduce the number of electricity-related fires, fatalities, injuries, and property loss.  We often take electricity for granted.  There are new ways of furnishing electricity, such as solar power and wind power.  The electricity that you use in your home travels through an electrical grid, going through an interconnected network of generating plants, transformers, and transmission lines.  

Solar power is derived from sunlight.  Sunlight can be directly utilized, converted in electrical energy, or converted into mechanical energy.  This is an important source of sustainable alternate energy.  Three common types of solar power are:

  •         Passive Solar
  •         Photovoltaic (Solar Cells)
  •         Solar Thermal (Electric Power Plants)

Solar power is advantageous for its cost effectiveness and environmental friendliness.  However, before choosing to install a solar power system for your home there are a variety of considerations.

  •          Your property should have open rooftop space or land that is free of shade five hours per day. 
  •          You should have your home evaluated by a licensed, qualified professional to ensure it can support this new technology.
  •          Only professionals should be hired to install and repair solar panels at your home or workplace.
  •          Building, electrical, and plumbing codes also apply to solar power installations.
  •         Solar power systems present unique safety challenges for fire fighters.  In the event of a fire, inform all officials of the use of solar panels as well as  identify the type used, in order to help them assess the risks. 

Wind power has become more mainstream in recent years.  The power of the wind is harnessed and transformed into electrical energy through the use of wind turbines; when wind blows over the blades of the wheel, it creates lift, causing them to turn.  The blades are connected to a shaft, which turns an electric generator, thus converting kinetic energy into electric energy.

Here again, there are certain aspects that homeowners should consider, such as:

  •          An average annual wind speed of at least 10 mph is considered necessary to make a small wind system economical.
  •          Determine the requirement and costs for connecting your system to the grid by checking with your utility company.
  •          Be sure of your household electricity needs and purchase the correct size wind turbine. 

We have named a couple of new sources of electric energy.  One thing remains: electricity is dangerous.  Here are some things you should know about electrical safety: 

  •          Arcing faults are one of the major causes of more than 50,000 home electrical fires that occur each year in the United States.  This is a dangerous problem caused by damaged, overheated, or stressed electrical wiring or devices.
  •          GFCI’s (Ground Fault Circuit Interrupters are designed to protect people from shock and electrocution.  They constantly monitor electricity flowing in a circuit, and switch off power if they sense any loss of current.  According to the Consumer Product Safety Commission, GFCI’s could prevent over two-thirds of home electrocutions that occur each year.
  •         TRR’s (Tamper Resistant Receptacles) look like regular outlets, but are designed with spring-loaded receptacle cover plates that close off the receptacle openings, or slots.  The 2011 National Electrical Code (NEC) requires installation of TRRs in all new homes because they have proven to be so effective.
  •          Every year in the U.S. more than 2,400 children under ten years old are treated in emergency rooms for electric shock or burns caused by tampering with a wall outlet, which could have been prevented by having TRRs in the home. 

It is estimated that electricity causes 140,000 fires each year.  Electricity kills almost 400 people and injures thousands more annually.  Most could have been avoided with an increased awareness of electrical safety.  Power line contact with construction equipment, ladders, and gardening tools are among the leading cause of electrocutions.  Flickering lights, overloaded circuits, and discolored outlets and light switch faceplates indicate the need for electrical upgrades.  By addressing these hazards, lives can be saved, injuries reduced, and economic losses caused by electrical fires will be lessened.

Utility company personnel are required to wear several types of Personal Protective Equipment, such as special safety glasses with dielectric hinges designed without metal parts, hard hats, antistatic shoes and antistatic coveralls (flame retardant).

DOWNED ELECTRICAL WIRES – SAFETY FIRST!

In almost all occupations, electrical hazards exist in some form.  Those hazards are multiplied for workers involved in cleanup and recovery efforts following major disasters.  A particular life-threatening danger exists around downed and low-hanging electrical wires caused from high winds, ice storms, or other weather-related troubles.

Some Safety Tips:

  • First, contact appropriate utility personnel.
  • Do not assume that a downed conductor is safe simply because it is on the ground, or not sparking.  Always consider all equipment, lines and conductors to be energized.
  • The circuits don’t always turn off when a power line falls into a tree or on the ground.  These downed power lines can kill you if you touch them, or the ground nearby.
  • Low-hanging wires still have voltage potential even if they aren’t touching the ground.
  • Never go near a downed or fallen electric power line.  Always assume that it is energized.  Fences, water pipes, bushes and trees, buildings, telephone/fiber optic cables, aluminum roofs, siding, sheds, etc., can also be energized by downed wires.
  • Some sources that create electrical backfeed are: circuit ties/switch points, lightning, generators, and downstream events.
  • Remember that electricity can travel away from its source.
  • Don’t touch anything that is touching the wire.
  • Never touch a person injured by a downed power line. Call 911 immediately.
  • If you are in your car, stay inside and use a cell phone for help.  Do not touch the outside of the car.
  • Finally, never drive over downed power lines.

OSHA
