Electrical Safety
Electricity is an essential part
of our lives. However, it has the potential to cause great harm.
Electrical systems will function almost indefinitely, if properly
installed and not overloaded or physically abused. Electrical
fires in our homes claim the lives of 485 Americans each year and
injure 2,305 more. Some of these fires are caused by electrical
system failures and appliance defects, but many more are caused
by the misuse and poor maintenance of electrical appliances,
incorrectly installed wiring, and overloaded circuits and
extension cords. Some safety tips to
remember:
- Never use anything but the proper
fuse to protect a circuit.
- Find and correct overloaded
circuits.
- Never place extension cords under
rugs.
- Outlets near water should be GFCI-type
outlets.
- Don't allow trees near power lines to be
climbed.
- Keep ladders, kites, equipment
and anything else away from overhead power
lines.
Electricity enters the home
through a control panel and a main switch where one can shut off
all the power in an emergency. These panels are usually
located in the basement. Control panels use either fuses or
circuit breakers. Install the correct fuses for the panel. Never
use a higher-numbered fuse or a metallic item, such as a penny.
If fuses are used and there is a stoppage in power, look for the
broken metal strip in the top of a blown fuse. Replace the fuse
with a new one marked with the correct amperage. Reset circuit
breakers from "off" to "on." Be sure
to investigate why the fuse or circuit blew. Possible
causes include frayed wires, overloaded outlets, or
defective appliances. Never overload a circuit with high-wattage
appliances. Check the wattage on appliance labels. If there is
frayed insulation or a broken wire, a dangerous short circuit may
result and cause a fire. If power stoppages continue or if a
frayed or broken wire is found, contact an
electrician.
Outlets and Extension
Cords
Make sure all electrical receptacles or outlets are three-hole,
grounded outlets. If there is water in the area, there should be
a GFCI or ground-fault circuit interrupter outlet. All
outdoor outlets should be GFCIs. There should be ample electrical
capacity to run equipment without tripping circuit breakers or
blowing fuses. Minimize extension cord use. Never place them
under rugs. Use extension cords sparingly and check them
periodically. Use the proper electrical cord for the job, and put
safety plugs in unused outlets.
Electrical Appliances
Appliances need to be treated with respect and care. They need
room to breathe. Avoid enclosing them in a cabinet without proper
openings, and do not store papers around them. Level appliances
so they do not tip. Washers and dryers should be checked often.
Their movement can put undue stress on electrical connections. If
any appliance or device gives off a tingling shock, turn it off,
unplug it, and have a qualified person correct the problem.
Shocks can be fatal. Never insert metal objects into appliances
without unplugging them. Check appliances periodically to spot
worn or cracked insulation, loose terminals, corroded wires,
defective parts and any other components that might not work
correctly. Replace these appliances or have them repaired by a
person qualified to do so.
Electrical Heating
Equipment
Portable electrical heating equipment may be used in the home as
a supplement to the home heating system. Caution must be taken
when using these heating supplements. Keep them away from
combustibles, and make sure they cannot be tipped over. Keep
electrical heating equipment in good working condition. Do not
use them in bathrooms because of the risk of contact with water
and electrocution. Many people use electric blankets in their
homes. They will work well if they are kept in good condition.
Look for cracks and breaks in the wiring, plugs and
connectors. Look for charred spots on both sides. Many things can
cause electric blankets to overheat. They include other bedding
placed on top of them, pets sleeping on top of them, and putting
things on top of the blanket when it is in use. Folding the
blankets can also bend the coils and cause
overheating.
Children
Electricity is important to the workings of the home, but can be
dangerous, especially to children. Electrical safety needs to be
taught to children early on. Safety plugs should be inserted in
unused outlets when toddlers are in the home. Make sure all
outlets in the home have face plates. Teach children not to put
things into electrical outlets and not to chew on electrical
cords. Keep electrical wiring boxes locked. Do not allow children
to come in contact with power lines outside. Never allow them to
climb trees near power lines, utility poles or high tension
towers.
Electricity and
Water
A body can act like a lightning rod and carry the current to the
ground. People are good conductors of electricity, particularly
when standing in water or on a damp floor. Never use any
electrical appliance in the tub or shower. Never touch an
electric cord or appliance with wet hands. Do not use electrical
appliances in damp areas or while standing on damp floors. In
areas where water is present, use outlets with GFCIs. Shocks can
be fatal.
Animal
Hazards
Mice and other rodents can chew on electrical wires and damage
them. If rodents are suspected or known to be in the home, be
aware of the damage they may cause, and take measures to get rid
of them.
Outside
Hazards
There are several electrical hazards outside the home. Be aware
of overhead and underground power lines. People have been
electrocuted when an object they are moving has come in contact
with the overhead power lines. Keep ladders, antennae, kites and
poles away from power lines leading to the house and other
buildings. Do not plant trees, shrubs or bushes under power lines
or near underground power lines. Never build a swimming pool or
other structure under the power line leading to your house.
Before digging, learn the location of underground power
lines.
Do not climb power poles or transmission towers. Never let anyone
shoot or throw stones at insulators. If you have an animal
trapped in a tree or on the roof near electric lines, phone your
utility company. Do not take a chance of electrocuting yourself.
Be aware of weather conditions when installing and working with
electrical appliances. Never use electrical power tools or
appliances with rain overhead or water underfoot. Use only
outdoor lights, fixtures and extension cords. Plug into outlets
with a GFCI. Downed power lines are extremely dangerous. If you
see a downed power line, call the electric company, and warn
others to stay away. If a power line hits your car while you
are in it, stay inside unless the car catches fire. If the car
catches fire, jump clear without touching metal and the ground at
the same time.
MORE SAFETY
PRECAUTIONS :
- Routinely check your electrical
appliances and wiring.
- Hire an InterNACHI inspector.
InterNACHI inspectors must pass rigorous safety training and are
knowledgeable in the ways to reduce the likelihood of
electrocution.
- Frayed wires can cause fires. Replace all worn, old and
damaged appliance cords immediately.
- Use electrical extension cords
wisely and don't overload them.
- Keep electrical appliances away
from wet floors and counters; pay special care to electrical
appliances in the bathroom and kitchen.
- Don't allow children to play with or
around electrical appliances, such as space heaters,
irons and hair dryers.
- Keep clothes, curtains and other potentially
combustible items at least 3 feet from all
heaters.
- If an appliance has a three-prong plug, use it
only in a three-slot outlet. Never force it to fit into a
two-slot outlet or extension cord.
- Never overload extension cords or wall
sockets. Immediately shut off, then professionally replace, light
switches that are hot to the touch, as well as lights that
flicker. Use safety closures to childproof electrical
outlets.
- Check your electrical tools
regularly for signs of wear. If the cords are frayed or cracked,
replace them. Replace any tool if it causes even small electrical
shocks, overheats, shorts out or gives off smoke or
sparks.
In summary, household electrocution can be prevented by
following the tips offered in this guide and by hiring an
InterNACHI inspector.
