Free Download – OSHA 1910.399 Electrical Glossary

Part of what we sell on our website at www.nationalsafetyinc.com is a set of training DVDs by Convergence Training. These are great training DVDs but that’s not what I’m going to talk about in today’s post. The reason I bring it up is because Convergence Training has made available an interactive glossary for OSHA 1910-399 Electrical standard and this download is 100% Free.

Check out their Electrical -General Requirements webpage. About halfway down the page you’ll see the glossary (screen shot shown below).

You can use it right from the webpage (if you do, don’t forget to bookmark it so you can come back to it next time you need it) or download it for use when you’re on the jobsite or without an internet connection.


Ground Fault Circuit Interruptor can protect your loved ones

When I bought my house, almost 3 years ago now, one of the first things that I did was to upgrade all the outlets in the bathrooms and kitchen with ground fault circuit interrruptors (GFCI). Why? Because GFCIs are able to detect the difference between the hot and neutral wires that come when electrocution is present. Simply put, they turn off the current when your toddler decides to put a fork in the socket.

GFCIs are especially important in areas where water is present (like the bathrooms and kitchen areas, as mentioned) because of the increased problem of electrocution in water but if you have small children, it’s a good idea to have all the outlets replaced. It has been estimated that there would be almost a third less electrocutions in homes if this was done.

Once you’ve installed (or had them installed), you need to know how to test them regularly to make sure they are working correctly.

To properly test GFCI receptacles in your home:

  • First, push the Reset button located on the GFCI receptacle to assure normal GFCI operation.
  • Plug a nightlight (with an ON/OFF switch) or other product (such as a lamp) into the GFCI receptacle and turn the product ON.
  • Push the Test button located on the GFCI receptacle. The nightlight or other product should go OFF.
  • Push the Reset button, again. The light or other product should go ON again.

If the light or other product remains ON when the Test button is pushed, the GFCI is not working properly or has been incorrectly installed (miswired). If your GFCI is not working properly, call a qualified, certified electrician who can assess the situation, rewire the GFCI if necessary or replace the device.

Safety Alert- Electrical Safety Awareness

May is National Electrical Safety Month

Electrical wiring improper installation, or damaged or deteriorated wiring and cords sparks an estimated 53,000 home fires each year. These fires cause more than 500 deaths, 1,400 injuries, and $1.4 billion in property damage and loss each year. Additionally, emergency rooms treat almost 2,500 children each year for injuries triggered by sticking objects into electrical outlets or getting kites tangled on electrical power lines.

All of these can be Prevented!

Top 10 Rules for Electric Safety

To play it safe around your home or work, just remember the rules for using electricity the right way.

1. DON’T plug a bunch of stuff into one outlet or extension cord.It could damage the electrical system in your house or even cause a fire.

2. Make sure all electric cords are tucked away, neat and tidy.

Pets might chew on electrical cords, and people might trip and fall.

3. DON’T ever climb the fence around an electrical substation.If a ball or pet gets inside the fence, ask a grown-up to call the electric company – they’ll come and get it out for you.
4. DON’T yank an electrical cord from the wall.Pulling on a cord can damage the appliance, the plug or the outlet.
5. Fly your kite far away from power lines or substations.The kite and the string may conduct electricity – sending it right through you to the ground.

6. Ask a grown-up for help when you need to use something that uses electricity.

7. DO look up and look out for power lines before you climb a tree.The electricity can go right through the tree branch – and right through you!

8. Have a grown-up put safety caps on all unused electrical outlets.

Covering outlets will also help save energy by stopping cold drafts.

9. Remind your mom or dad to watch out for power lineswhen they’re using a ladder, chainsaw or other outdoor equipment.10. Keep electrical stuff far away from water.

Most electrical accidents around the house happen when people use electricity near water.

General Electrical Safety Tips

· Replace or repair loose or frayed cords on all electrical devices.

· Avoid running extension cords across doorways or under carpets.

· In homes with small children, unused wall sockets and extension-cord receptacles should have plastic safety covers.

· Consider having additional circuits or outlets added by a qualified electrician so you do not have to use extension cords.

· Follow the manufacturer’s instructions for plugging an appliance into a receptacle outlet.

· Avoid overloading outlets. Plug only one high-wattage appliance into each receptacle outlet at a time.

· If outlets or switches feel warm, shut off the circuit and have them checked by an electrician.

· When possible, avoid the use of “cube taps” and other devices that allow the connection of multiple appliances into a single receptacle.

Polarized and 3-Prong Plugs

· Polarized plugs have one blade that is slightly bigger than the other. This design makes sure that plugs are plugged into outlets correctly and also reduces the risk of electric shock. NEVER shove a polarized plug into a non-polarized outlet or extension cord.

· 3-prong plugs also help to reduce the risk of electric shock. NEVER remove the 3rd prong in order to make it fit into a 2 prong outlet or extension cord.

Light Bulbs

· Check the lamps wattage and use the appropriate watt light bulb.

· Make sure that light bulbs are screwed in securely to prevent overheating.

· Place lamps on level surfaces, away from things that can burn.

· If you smell a faint burning or rubbery smell from a lamp then the wattage level of the light bulb is too high for the lamp and it should be replaced with the appropriate bulb.


· Make sure that all appliances have been tested by an independent research laboratory and be sure to follow all manufacturers instructions carefully.

· Appliances that take a lot of power to operate, such as space heaters and halogen lamps, should be plugged directly into an outlet. These appliances should not be plugged into extension cords.· One Outlet One Plug! Dont overload electric outlets with several plugs. If multiple appliances must share one outlet, be sure to use only one appliance at a time.
Water and appliances dont mix!· Dont leave appliances plugged in where they may come into contact with water.

· If an appliance falls into water DO NOT reach in to pull it out. First turn off the power and unplug the appliance.

· Dont use electric appliances or take showers or baths during an electric storm. Using electricity during an electric storm increases your risk of getting an electric shock.

Hunt for Home Electrical Hazards

Keep an eye out for these warning signs. If any of these are present in your home there could be a risk of an electric fire or electrocution.

· Frequent power outages or blown fuses. This may indicate that your home wiring needs to be updated or repaired. Contact a licensed electrician.

· Overloaded electrical outlets

· Dim or flickering lights

· Sparks or sizzling sounds in outlets or walls

· Overheated plugs, cords or switches

· Smells of something burning or rubbery smells

· Frayed wires or cracked cords Feeling a mild shock or tingle when you plug in an appliance.

Starting a New Outdoors Project?Call Dig-Safe at 811 before any digging or excavation work to prevent any electrical danger.

Safe Extension Cord Use

Extension cords deliver electrical power to where its needed. But when they are misused, they can also become electrical hazards.

The U.S. Consumer Product Safety Commission (CPSC) estimates that some 3,000 people are treated each year for injuries associated with extension cords. In addition, the CPSC reports that improperly functioning extension cords cause 5,000 residential fires annually. The Electrical Safety Foundation International (ESFI) suggests following these cord safety tips to help avoid shock and fire hazards.

Remember, extension cords are intended for temporary use.

Never run extension cords through walls, under rugs or furniture, or across doorways.

Never try to repair a damaged extension cord with electrical tape; replace it instead.

Never overload an extension cord. If any part of the cord feels warm to the touch, the cord is drawing too much power and could present a fire or shock hazard.

Never cut off the ground pin to connect a 3-prong appliance cord to a 2-wire extension cord or receptacle. Always use a UL-listed adapter for this purpose.

Replace older extension cords if one of the prongs in the plug is not “polarized.” In a polarized plug, one prong will be wider than the other.

Do not allow extension cords to dangle from counters or tables, where someone could accidentally pull them down or trip over them.

Always plug an appliance in to the extension cord before plugging the extension cord into a wall receptacle. Also, make sure the appliance is “off” before plugging it in.

When disconnecting an extension cord, pull from the plug, not the cord itself.

Cover unused outlets on the extension cord to prevent children from making contact with a live circuit.

Before buying any extension cord, check to ensure that the product has been listed by a nationally recognized laboratory, such as Under-writers Laboratories (UL) or Canadian Standards Association (CSA)

Use special, heavy-duty extension cords for high-wattage appliances such as air conditioners, portable electric heaters and freezers.

When placing furniture or an appliance directly up against a wall where a cord is plugged into a receptacle, use a low-profile type of plug. These plugs will let the appliance or furniture get closer to the wall, and there is less chance of the plug coming loose.

Outside the home, use extension cords designed expressly for outdoor use.

Arc Faults

What is an arc fault?

Arcing faults often occur in damaged or deteriorated wires and cords. Some causes of damaged and deteriorated wiring include puncturing of wire insulation from picture hanging or cable staples, poorly installed outlets or switches, cords caught in doors or under furniture, furniture pushed against plugs in an outlet, natural aging, and cord exposure to heat vent and sunlight.

Ground Fault Circuit Interrupters (GFCIs)

One of the most important safety devices in your home is a simple electrical device called a Ground Fault Circuit Interrupter (GFCI). Estimates indicate that the installation of GFCIs have saved hundreds of lives and prevented thousands of injuries in the U.S. over the past 30 years.

GFCIs are designed to provide protection against electrical shock from ground faults, or leakage currents, which occur when the electrical current flows outside of the circuit conductors. If a person becomes part of a path for leakage current, he or she will be severely shocked or electrocuted.

If GFCIs were installed in every U.S. home, experts suggest that nearly 70 percent of the approximately 400 electrocutions that occur each year in the home could be prevented.


· Put a ground fault circuit interrupter (GFCI) between your electric power source and your electric product.

· Test your GFCI monthly and after every major electrical storm.

· If you have a home without GFCIs, consult a qualified, licensed electrician about adding this important protection, purchase plug-in units or a portable GFCI to provide individual receptacle or load protection.

· GFCIs are products designed to prevent serious injury or death from electrical shock by detecting ground faults at very low levels.

· A GFCI should be used in any area where water may come in contact with electrical products. GFCIs are now required by code in certain areas of the home, including unfinished basements, kitchens, bathrooms, bedrooms, garages, crawl spaces and around swimming pools.

· If a GFCI senses minimal current leakage to ground in an electrical circuit, it assumes a ground fault has occurred. It them interrupts power fast enough to prevent serious injury from electrical shock.

· Three types of GFCIs are designed for home use-wall receptacle, circuit breaker and portable plug-in. All three are readily available, inexpensive and fairly simple to install.


Surge protectors and UPS devices protect equipment, but they do not protect from the potential hazards of an overloaded circuit. Make sure the electrical load is not too great for the circuit. A licensed electrician can check your electrical system and provide guidance on the capacity of electrical circuits in your office.

Telltale signs of overloading include:

  • outlets warm to the touch;
  • outlets that are discolored;
  • circuit breakers that frequently trip
  • fuses that frequently blow;
  • burned insulation odors; and
  • extension cord that are warm to the touch.
  • To prevent these electrical hazards, contact a licensed electrician to install dedicated circuits where needed. It is also smart to install outlets to eliminate the use of extension cords.

Burn Awareness Week Feb 6-10

Burn Awareness Week Feb 6-10

As 75 to 80 percent of burn injuries happen in and around the workplace or at home, it is important for you to be aware of risks and take precautions to make your work place and home safe for you and your family. Each year in the United States, 1.1 million burn injuries require medical attention. Approximately up to 4,500 people die every year in the U.S. from burns and related infections. Included below is information from the American Red Cross Emergency Services to help you learn more about burns, how to prevent them and what to do if you or a family member or co-worker sustains a burn.

What is a burn?
Very simply, a burn is damage to the skin and underlying tissue. It is caused by heat, chemicals, radiation or electricity, and may damage or destroy skin cells. Deeper burns may involve the fat, muscle or bone. Scalds result when one or more layers of skin are destroyed by contact with hot liquid or steam.

The depth of injury depends on two things:

  • temperature to which the skin is exposed
  • length of time the skin is exposed to the burning substance

The higher the temperature, the shorter amount of time is required to inflict a burn injury.

What are the most common causes of burns?
Burns may be caused by several different mechanisms, each with their own complications:

  • Scalds– these types of burns result when skin comes into contact with hot liquids (spilled liquids or food, hot bathwater)
  • Contact burns– these burns result from contact of the skin with hot items, including flames
  • Chemical burns– these burns result from contact of the skin with chemicals, or by ingestion of chemicals
  • Electrical burns– these types of burns result when a person comes into contact with a source of electrical energy; includes burns caused by electrocution and lightning strike
  • Radiation burns- these types of burns result from contact with a source of radiation; may include overexposure i.e. sunburn

Burns may be classified according to the tissue damaged (first, second or third degree) and also according to the mechanism of burn injury. Knowing the types of burns allows health professionals to tailor their treatment accordingly and predict which patients require more specialized care, as well as which patients are more at risk for complications.

What are the symptoms of each degree of burn?
First degree (Superficial)

  • Causes sunburn, minor scalds
  • Generally heals in three to five days with no scarring

Characteristics of Injury:

  • Minor damage to the skin
  • Color: pink to red
  • Painful
  • Skin is dry without blisters

Second degree (Partial thickness)


  • Damages but does not destroy top two layers of the skin
  • Generally heals in 10 to 21 days
  • Does not require skin graft

Characteristics of Injury:

  • Skin is moist, wet and weepy
  • Blisters are present
  • Color: bright pink to cherry red
  • Lots of swelling
  • Very painful

Third degree (Full thickness)

  • Destroys all layers of the skin
  • May involve fat, muscle and bone
  • Will require skin graft for healing

Characteristics of Injury

  • Skin may be very bright red or dry and leathery, charred, waxy white, tan or brown
  • Charred veins may be visible
  • Cannot feel touch in areas of full thickness injury

At what temperature can water burn a person?
Children and seniors sustain severe burns at lower temperatures and in less time than adults. Because their skin is thinner, they cannot react quickly to escape the hot water or they lack skin sensitivity due to other medical conditions. Water temperatures figured in both Celsius and Fahrenheit for those of you that have a foreign made water heaters.

Water temperature          Time required for a third degree burn
68 degrees C/155 F              1 second
64 degrees C/148 F              2 seconds
60 degrees C/140 F              5 seconds
56 degrees C/133 F             15 seconds
52 degrees C/127 F              1 minute
51 degrees C/124 F              3 minutes
48 degrees C/120 F              5 minutes
37 degrees C/100 F              Safe temperature for bathing

How do I ensure safe water temperatures in my home?
To protect your family, you can apply one of these methods:

  • The thermostat of a hot water heater can be set to deliver water at around 48 degrees Celsius(C) or 120 degrees Fahrenheit (F). Depending on the type of tank you have it is recommended that you consult an electrician.
  • Devices, known as mixing valves or tempering valves, can be installed in the plumbing lines. These devices ensure that water is delivered at 48/120 degrees C/F by mixing in cooler water as needed.
  • Devices, known as anti-scald devices, can be installed at individual taps or faucets. If the water gets too hot, a valve inside these devices slows the water to a trickle. You then restart the water by mixing more cold water into the tap.

To install these devices, it is recommended that you contact your local plumber. It is important to note that potentially harmful bacteria can grow in water heaters if set too low. Do not lower the temperature of your household water heater below 48/120 degrees C/F. Those with weak immune systems, lung and respiratory problems or organ transplants should check with their doctors before reducing the temperature of the water in their homes. Most families, however, can safely lower their water temperature to 48/100 degrees C/F without concern for other health risks as well as electric.

Burns can also come from gases and liquids. Here are the flashpoints for some common liquids and gases found around the home or workplace:

FLAMMABLES                                                              FLASHPOINT

Safety Solvents                                                            100-140°F

Diesel Fuel                                                                    125°F

Paint Thinner                                                                 105°F

Kerosene                                                                      100°F



Turpentine                                                                     95°F

Gasoline                                                                       -45°F

Propane                                                                        -156°F

How can I help prevent burns from happening to me or my family?

— Turn pot handles toward back of stove. Keep long cord appliances toward back of counter.
— Keep children at a safe distance from all hot items by using playpens, high chairs, etc.

— In a hotel if there is a fire alarm check the door or knob with the back of your hand for heat before opening doors

— Don’t cook with children underfoot. Create a safe zone.
— Never hold an infant or child while pouring or drinking hot liquids.
— Turn water heater temperature down to 120 degrees Fahrenheit.
— Always check water temperature before placing child in tub.
— NEVER leave your child unattended in the kitchen or bathtub.
— Put sunscreen on you and your children.
— Use safety plugs to cover electrical outlets.

— Never spray charcoal lighter fluid or gas on charcoal that has already been lit.
— Keep a screen or glass cover over your fireplace.
— Keep matches and lighters in a locked box, out of reach of children.
— Install smoke alarms on every level and in every sleeping area of your home. Test them once a month and replace batteries when necessary.
— Always place hot items on a secure surface to avoid accidental tipping.
— Never, never bury hot barbecue coals- extinguish with water first.

First Aid

What you do to treat a burn in the first few minutes after it occurs can make a huge difference in the severity of the injury.

Immediate Treatment for Burn Victims

  1. 1.     Stop, Drop, and Roll” to smother flames.
  2. 2.     Remove all burned clothing. If clothing adheres to the skin, cut or tear around burned area.
  3. 3.     Remove all jewelry, belts, tight clothing, etc., from over the burned areas and from around the victim’s neck. This is very important; burned areas swell immediately.

What do I do if I or someone I know is burned?

1. Cool burn with water
Immediately pour cool water on burns or soak them for at least three to five minutes (20 minutes for a chemical injury). DO NOT USE ICE. Ice may cause more damage, stick to the burn and remove the skin. For scalds, immediately remove hot, wet clothing.

2. Do not apply ointments or butter
Use only cool water on burns. Ointments, butter, creams or salves allow the burn to retain heat, may cause infection and may hinder medical evaluation.

3. Cover the burn
Apply a soft, clean, dry dressing, bandage or sheet to the burned area. Do not break blisters, as this could let germs into the wound. Cover burn victims and keep them warm.

4. See a doctor
Adults should see a doctor if the burn is larger than the size of a quarter. Infants, young children and the elderly are endangered by even small burns, and should see a doctor. 

Prevention and Sun Burn exposure /Tanning and Burning

When ultraviolet (UV) rays reach the skin’s inner layer, the skin makes more melanin. Melanin is the pigment that colors the skin. It moves toward the outer layers of the skin and becomes visible as a tan.

A tan does not indicate good health. A tan is a response to injury, because skin cells signal that they have been hurt by the sun’s UV rays by producing more pigment.

People burn or tan depending on their skin type, the time of year, and the amount of time they have spent in the sun. The six types of skin, based on how likely it is to tan or burn, are—

  • I: Always burns, never tans, sensitive to sun exposure.
  • II: Burns easily, tans minimally.
  • III: Burns moderately, tans gradually to light brown.
  • IV: Burns minimally, always tans well to moderately brown.
  • V: Rarely burns, tans profusely to dark.
  • VI: Never burns, deeply pigmented, least sensitive.

Although everyone’s skin can be damaged by too much sunlight, people with skin types I and II are at the highest risk.

Prevention can save lives, long term affects of sun burns and radiation can lead to melanoma, basil cell cancer or cataracts.

Basal Cell Carcinoma

The most common form of skin cancer, basal cell carcinoma is the most easily treatable and least likely to spread, though it can damage surrounding tissue. Because basal cell carcinoma spreads slowly it occurs mostly in adults. Basal cell tumors can take on many forms, including a pearly white or waxy bump, often with visible blood vessels, on the ears, neck, or face. Tumors can also appear as a flat, scaly, flesh-colored or brown patch on the back or chest, or more rarely, a white, waxy scar.


Melanoma is not as common as other types of skin cancer, but it’s the most serious and potentially deadly. Possible signs of melanoma include a change in the appearance of a mole or pigmented area. Consult a doctor if a mole changes in size, shape, or color, has irregular edges, is more than one color, is asymmetrical, or itches, oozes, or bleeds. Melanoma can affect the skin only, or it may spread to organs and bones. It can be cured if it’s found and treated early.


A cataract is a cloudy area in the lens of the eye that blocks the passage of light to the retina. Cataracts are painless but may cause vision problems, including foggy vision, glare from light, and double vision in one eye. Prevent cataracts by wearing a hat and sunglasses when in the sun.

 Shun the Sun

The best way to prevent sunburn, premature wrinkles, skin cancer, and other damaging effects from the sun is to stay out of it, especially between 10 a.m. and 4 p.m., when the sun’s rays are strongest. If you can’t, apply sunscreen with an SPF of 30 or more liberally (don’t forget the lips and ears!), wear a hat and sunglasses, and cover up with clothing when outdoors. If you notice changes to your skin such as a mole changing appearance, a new growth, or a sore that won’t heal, see a doctor right way.

Tips for electrical system maintenance and upkeep

Most of us only think about our electrical system when it shorts or blows. By then, it’s usually something that requires an electrician and is going to cost us. Whether we are talking about your home or your place of business, there are some simple things that you can do to make sure you don’t have to call the electrician, or worse, end up with an electrical fire.

  1. Use surge protectors on all computers, televisions, sound systems and other electronics. A surge protector is cheap, especially when compared to the cost of replacing your HDTV because a power surge fried it. And don’t forget to use a surge protector on your laptop too when you plug it in.
  2. Don’t overload any one circuit. Be aware of how much power your appliances and electronics need and make sure to spread the demand around to avoid overloading.
  3. Avoid leaving unused electronics plugged in when not in use for an extended period of time. Even if they are turned off, they are using power. Don’t leave your cell phone and laptop charger plugged in when not in use (even when they aren’t charging they are sucking power).
  4. Make sure that all your appliances are in good working order. Old and damaged appliances and furnaces use more power then appliances and heating systems that are new and/or well maintained. Change the filter in your central air and/of furnace at least every 90 days when in use. Clogged filters overwork and overheat the furnace and central air. While you’re at it, check the dryer vent to make sure it isn’t clogged as well.
  5. Any time you are doing any kind of electrical work, make sure that your electrical panel is locked out to avoid having someone accidentally flip the circuit back on. There are a wide variety of electrical lockout products available to keep you from being accidentally electrocuted while you are working.
  6. Keep up with all product recalls. The Consumer Product Safety Commission website is consistently kept up to date. A few minutes a month could save you’re a world of grief. Other websites to check out include www.saferproducts.gov and http://www.recalls.gov/
  7. Know your limitations. Electricity can kill so be honest with yourself and know when to call in a licensed electrician. No all projects are do-it-yourself ones. Some are best left to professionals.

The Basics of Welding Safety (Part 5)

Electrical Safety Issues

The basic principles of welding involve electrical current that is essentially being shorted at the tip of the welding rod to produce the heat needed to melt the rod and the steel long enough for them to bond and create the weld. This means, of course, that we are dealing with electrical current and that certain precautions must be taken in order to work with that current without danger.

  1. Both the electrode, as well as the work are hot (have electricity running through them) and must never be touched with bare skin or with anything that is wet.
  2. In semiautomatic or automatic wire melding almost all of the equipment (wire, electrode, reel, welding head and nozzle) is hot and should be treated with caution.
  3. Always make sure that your work is properly ground and that there is a good electrical connection with the metal being welded. The connection should be as close to the area being welded as possible.
  4. Make sure that all equipment is in good working condition. Remove and replace any frayed or faulty equipment.
  5. Never touch equipment from two different welding units as your body could create an electrical bridge and cause electrocution.
  6. Never work on any of the equipment until it has been disconnect completely. Never try to fix it while it is still hot.
  7. Always turn off all equipment when not in use.
  8. Make sure all equipment is installed and running according to code.
