INTRODUCTION
Reasonable people, knowing the danger, would never
stand under a tree or on a hill during a thunderstorm where they might
be struck by a bolt of lightning. Yet, these same people sometimes
become careless about protecting themselves and their families against
other outdoor electrical hazards that can cause a fire, produce a shock
or even electrocute.
Water, which doesn't mix with electricity, can be
found in unexpected places outdoors.
A tall ladder, even wooden, carried in an upright
position can accidentally contact an overhead power line with possibly
fatal results.
This pamphlet explains electrical safety devices that,
when properly used and maintained, can reduce or prevent accidents. It
lists do's and don'ts for electrically-powered or cordless products
commonly used outdoors. Read through and follow these electrical safety
guidelines to make your outdoor life safer and more enjoyable.
ELECTRICAL SAFETY DEVICES
WHAT ARE ELECTRICAL SAFETY DEVICES?
Four devices that help provide outdoor electrical
safety: Circuit breakers or fuses
protect against overcurrent conditions that
could result in potential fire and shock hazards.

Ground-fault circuit interrupters
(GFCls) protect against potentially lethal shock when they detect
even minute, but potentially dangerous ground
faults, or "leaks" of electrical current from the
circuit. GFCIs may be incorporated into circuit breakers protecting the
entire circuit, outlets protecting everything on the circuit downstream
from the GFCI outlet, or as portable devices that can be used at an
outlet to give protection for a particular electrical item.
Three-pronged plugs and outlets,
and polarized plugs and outlets offer enhanced protection against
potential shock when provided on specific products. These measures
should never be circumvented by sawing or breaking off the third prong
or attempting to widen an outlet slot.
Arc fault circuit interrupters (AFCls)
are relatively new devices that protect against fires caused by the
effects of unwanted electrical arcing in wiring. An AFCI will
de-energize the circuit when an arc fault is detected.
Electrical wiring in buildings with areas exposed to
the outdoors, including circuits in garages, porches, patios and storage
areas, could benefit from the additional electrical fire prevention
features of AFCI devices when incorporated in the branch circuitry.
HOW DO ELECTRICAL SAFETY
DEVICES WORK?
Circuit breakers or fuses
in your home electrical panel sense overcurrent
conditions and short circuits and reduce the
risk of fire in your electric wiring. When you overload a branch circuit
by plugging in too many products, the fuse
blows or the circuit breaker trips to shut
off power.
Up-to-date single-family dwellings should be provided
with at least one branch circuit that carries power to an outdoor
outlet. Locate your outdoor branch circuit(s) on the listing of branch
circuits on your electrical panel. (If you have no outdoor wall outlet,
call a qualified electrician to install one.) You should find the amperage
on the circuit breaker or the fuse.
To figure out whether a combination of products will
overload a branch circuit, add up the power ratings (watts)
you plan to use at the same time on that circuit. The power (watts)
or amperage of an electrical product is
shown on its attached nameplate.
Volts (also on nameplate)
x Amps = Power (wattage)
For example: 120 V x 15A= 1800 W Demanding more than 1800 W will
overload a 15 ampere circuit.
Outdoor electrical products that may use a significant
portion of the power a branch circuit can supply are electric lawn
mowers, leaf blowers and snow blowers.
Be sure to figure total wattage
in advance when you are planning an outdoor event. Add up the power
ratings of everything you will use: garden lights, electric grill, hot
tub and so on plus everything else on the circuit. If you exceed the
circuit wattage limitation, you will likely trip a circuit
breaker or blow a fuse which can
cause hidden damage to the circuit. If necessary, plan to redistribute
your power needs to more than one branch circuit, or reduce the
electrical load to avoid the overload situation.
A short circuit in a
product, cord or plug may also trip your circuit
breaker or blow a fuse. If you can
identify the product that is causing the problem, take it to a
manufacturer-recommended repair facility. If you don't know what is
causing your circuit breaker to trip or fuses
to blow, call a qualified electrician.
A ground-fault
circuit interrupter (GFCI) will disconnect power automatically
when a plugged-in electrical product leaks electricity to ground.
Outdoors, where water and electricity can easily inadvertently come
together, a GFCI is a lifesaver, not a luxury. A GFCI is a simple device
reasonably priced. If you are unsure about installation, seek a
qualified electrician.
GFCIs protect against shock or electrocution when a
plugged-in electrical product is dropped into a sink, pool, pond,
puddle, or hot tub (a shock may be felt in the split second before the
GFCI trips). A GFCI also cuts off current when a person contacts a
product like an electric heater or an electric power tool, which may be
"leaking electricity."
The National Electrical Code now requires GFCIs for
protection in the bathroom, garage, kitchen and outdoor outlets of new
homes.
|
Outlet type GFCI
|
Circuit breaker type GFCI
|
Portable type GFCI
|
No GFCls installed?
Buy one. GFCIs come in several models, including a
portable plug-in type.
Attach a portable GFCI between the power re¬ceptacle
and the plug of any electric saw, lawn edger, weed trimmer or other
outdoor (or in¬door) electrical equipment; or have a qualified
electrician install receptacle or circuit breaker GFCI protection for
your family. Make sure you have GFCIs for swimming pool underwater
lighting circuits, for electric circuits of hot tubs, and for wall
outlets within 20 feet of such pools as required in the National
Electrical Code.
Testing GFCIs
To be sure your life-protecting GFCIs are working
properly, use this test or the instructions that come with the GFCI.
1. Plug a night light (or radio turned up loud, if you
have a circuit breaker GFCI) into a GFCI-protected wall outlet, and turn
it on.
2. Press the GFCI test button or switch. The light or
radio should go off.
3. Press the reset feature to restore power.
If the light or radio does not go off when the test
button or switch is pressed, the GFCI is not working or is not wired
correctly. Contact a qualified electrician to correct the problem or
install a new GFCI.
A 3-pronged plug used in a
3-hole outlet protects against shock from a defective electrical
product, cord orplugwith grounding problems.
Electricity to poweryour electrical products travels
along a path called a circuit. As long as it stays in its intended path
while traveling to "ground," it
does its job with minimal risk of electric shock. But when a product,
cord or plug is damaged, out-of-path electricity may energize expose
metal parts as it seeks a new path to ground.
If you come in contact with energized conductive parts and provide a
path to ground, the electricity will deliver a shock. The third prong on
a plug is there to carry any stray electricity to ground
through a 3-pronged receptacle.
Many electrical products designed for outdoor use have
3-pronged plugs (except for power tools and
other products which may protectyou against shock with a system of
double insulation).
Never,
ever, remove the third prong of a 3-prong plug.
If your outdoor wall outlet has room for only 2
prongs, you should replace it with a GFCI-protected, 3-hole grounding
type receptacle. When using a 3-to-2 grounding adapter, be certain that
the receptacle itself is grounded or GFCI-protected
for the adapter to work. Use a circuit tester (available in hardware
stores) to find out if your outdoor receptacles are grounded,
or call a qualified electrician to help you make sure.
Arc-fault circuit
interrupters (AFCls)
Problems in home wiring, like arcing and sparking, are
associated with more than 40,000 home fires each year. These fires claim
over 350 lives and injure 1,400 victims annually.
A new electrical safety device for homes, called an arc
fault circuit interrupter or AFCI, is expected to provide
enhanced protecting from fires resulting from these unsafe home wiring
conditions.
Typical household fuses
and circuit breakers do not respond to early
arcing and sparking conditions in home wiring. By the time a fuse
or circuit breaker opens to defuse these
conditions, a fire may already have begun.
Requiring AFCIs
AFCIs are already recognized for their effectiveness
in preventing fires. The most recent edition of the National Electrical
Code, the widely-adopted model code for electrical wiring, requires
AFCIs for bedroom circuits in new residential construction, effective
January 2002.
Future editions of the code, which is updated every
three years, could expand coverage to other circuits,
including outdoor circuits.
Hazards In Use of
Electrical Products Outdoors
How to Avoid Outdoor Electrical Accidents
| Water |
Keep outlets covered. Use a Ground
fault circuit interrupter (GFCI). Keep products with line
cords away from sinks, puddles, pools, ponds, and hot tubs. Keep
outdoor outlets weather-protected
with outlet covers. |
| Disabled 3-prong plug |
Never remove third prong. Dispose of electrical
items and extension cords with damaged prongs. |
| Damaged product wiring |
Replace or have damaged parts, cords, plugs
repaired by qualified professionals before use. |
| Improper product operation. Exposed blades or
moving parts |
Read instruction manual. Use goggles or other
safety aides. Never bypass a safety device. |
| Unattended products |
Switch off, unplug, store and lock products not
in use. |
| Extension cord misuse |
Match product power needs (on product labels
and in manuals) to extension cord label information and make
sure they are rated appropriately for outdoor use. |
| Improper product storage |
Store outdoor electrical products indoors. |
| Overloaded branch circuits |
Limit power use on each branch circuit to its
rated capacity. |
| Use of indoor product outdoors |
Use only weather-resistant products outdoors. |
| Power line contact |
Contact your regional utility protection center
(such as Digsafe, Call Before You Dig, or Miss Utility) to
locate buried power lines before digging or drilling. Locate
overhead power lines before trimming trees, flying kites or
house painting, and keep ladders away. |
| Pad-mounted electrical equipment |
Keep off and away from this electrical
equipment. If you notice the cabinet doors or locks have been
tampered with or left open, contact your local utility
immediately. |
| Gasoline, naphtha fumes |
Avoid where electrical sparks may cause fire or
explosion. |
For more information, contact CPSC (1-800-638-2772 or www.cpsc.gov),
ESFI (703-841-3296 or www.electrical-safety.org)
or your local utility company.
Before you use any
electrical products outdoors:
 | Make sure it was intended for outdoor use. Does the
product's instruction manual or an attached label warn, "Not
for Outdoor Use" or "Indoor Use Only"? Unless an
electrical product is designed to be weather resistant, a sudden
summer shower can ruin the product and turn it into a serious shock
hazard. Most electrical products intended for continuous outdoor use
have heavily insulated cords and molded-on plugs to prevent moisture
from seeping in.
| Study all instructions carefully. Keep the
instruction manual where you can easily find it. Reread it from time
to time to refresh your memory.
| Inspect products for damaged cords, plugs or
wiring. Turn the product off and unplug it if a cord overheats. Take
a damaged product to the manufacturers authorized repair center or
have a qualified electrician repair it. |
| |
Make sure a recognized testing laboratory certifies
the product. This insures that the product is designed and manufactured
in accordance with established safety standards. Look for these and
other markings of internationally recognized testing laboratories:
SAFETY RULES
Follow these safety rules for every electrical
product you use outdoors:
Outdoor portable electrical appliances and
power tools should always be:
| Plugged in and turned on only when in use.
| Turned off and in lock position when being carried
or hooked up to attachments like mower baskets or saw blades.
| Stored indoors (with a few exceptions such as
electric barbecue grills, which can be covered to remain outdoors)
and away from water and excessive heat.
| Used only when all safety guards are in place.
Sharp blades and rapidly moving parts can cut off a finger or a toe. |
| | |
Outdoor portable electrical appliances and
power tools should never be:
| Left unattended outdoors, even when you leave
temporarily. If there is a key, remove it. Put the product where no
curious child or unqualified adult can misuse it.
| Plugged in while the switch is in the
"on" position or while being carried or moved.
| Carried by their cords.
| Used while wet or dose to water.
| Used near sharp edges or in conditions which can
damage the product, its cord or its plug. Loose and broken wires are
both shock and fire hazards.
| Repaired by anyone who is not a licensed
electrician, authorized by the manufacturer or trained to repair the
particular product. |
| | | | |
Follow these rules to avoid water hazards:
| Keep outdoor outlets covered and dry between uses.
New outlet covers are available that offer weather protection while
a plug is inserted into the outlet.
| Except for electric snow blowers and other
appliances designed for use in a wet environment, select a dry day
to power-up outdoors.
| Keep cords and plugs away from sweating pipes and
puddles.
| If an electrical product falls into water, make
sure you are dry and not in contact with water or metal surfaces and
unplug it immediately. Do not reach into the water for it.
| Use a ground-fault circuit
interrupter (GFCI). |
| | | |
HOT TUBS, SPAS, AND POOLS
Follow these rules to avoid hot tub, spa, and pool hazards:
| Keep outlets near hot tubs, spas and pools covered
and dry between uses. New outlet covers are available that offer
weather protection while a plug is inserted into the outlet.
| Keep cords and plugs away from hot tubs, spas and
pools and puddles from wetbathers. Never handle electrical items,
plugs or outlets when wet.
| If an electrical product falls into water, do not
reach into the water for it. Make sure you are dry and not in
contact with water or metal surfaces and unplug it immediately or
shut off the circuit powering the item.
| Hot tubs, spas and pools, and outlets on or near
them should be protected by a ground-fault
circuit interrupter (GFCI). Many older swimming pools that
pre-date the introduction of GFCIs in the 1970s should be upgraded
to add GFCI protection for branch circuits supplying power to
underwater pool lights operating above 15 volts, and outlets within
20 feet of the pool. |
| | |
Note, however, that when a person is immersed in an
isolated body of water, like a hot tub, the water could become
electrified without involving a ground fault as the electric current
passes through water (and perhaps a person) from one electrical pole to
the opposite pole. In this case, the GFCI may not provide shock or
electrocution protection.
EXTENSION CORDS
Guidelines for selecting and using outdoor extension cords:
| Use only extension cords marked "For Outdoor
Use." Weather-resistant, medium-to-heavy gauge
extension cords have connectors molded onto them to prevent moisture
from seeping in and outer coatings that are designed to withstand
being dragged along the ground.
| Outdoor extension cords come in 25 to 150 foot
lengths. Buy only the length you need. Above 100 feet you can lose
power-a hazard when using power tools.
| Use three-wire extension cords with 3-pronged
plugs. Exception: Extension cords for use with appliances and tools
that are "double-insulated."
| Completely connect plugs. Push them in all the way.
Do not plug one extension cord into another.
| Unwind cord before using. Do not use if damaged. Do
not cover or walk on cords.
| Never leave an open line (no product plugged into
the end of an extension cord while it is plugged into an outlet).
Not even for a minute. Always unplug cords not in use.
| Never leave extension cords outside in the snow or
very cold weather for extended periods.
| Replace outdoors extension cords every three or
four years if damage is noted. |
| | | | | | |
Match each outdoor electrical product to its
extension cord:
| Match power needs (amperage)
of electrical products with amperage rating
of extension cords.
| The extension cord capacity should be as high as or
higher than that of the electrical product attached to it. Amperage
ratings for outdoor electrical products can range from
"1 A" for a bug killer to "15 A" for a snow
blower and are found on nameplates attached to products. Compare
them to the rating information on extension cord packaging and on
labels permanently attached to cords. |
|
To convert amps to watts,
multiply by 120 volts. For example, 10 A x
120 V = 1200 W.
Match the extension cord gauge
to the amperage rating of the product. AWG
on the above label stands for American Wire Gauge. Cords for outdoor use
are generally either 12 AWG (heavy) or 14 AWG (medium).
ELECTRICAL LAWN & GARDEN
PRODUCTS
Follow every general safety rule for outdoor
electrical products when using electrical lawn and garden products. Then
take some extra precautions.
Lawnmowers and other lawn and garden equipment with
sharp blades and rapidly moving parts can cause serious injury by
cutting off a finger or a toe. Never remove the guards.
Keep children well away from lawnmowers and other
products, which can throw objects such as rocks and sticks.
Products like power shovels or diggers, lawnmowers,
mulchers, tillers, thatchers and leaf or snow blowers move and have
moving parts that can cut, burn, even blind when di¬rections are not
followed. Study each product's manual for safe operation rules.
Mowing a lawn:
| Clean area first; remove rocks, branches, wires,
bones or other foreign objects that can be thrown by blades.
| Avoid wet grass.
| Mow only in daylight.
| Always wear enclosed shoes.
| Never remove safety guards or adjust wheel height
while motor is running.
| Keep cords out of working path.
| Avoid loose clothing and jewelry that can catch on
moving parts.
| Keep bystanders, especially children away.
| Push, don't pull. Mow across not up and down
slopes.
| Clipping, trimming a hedge or edging, wear safety
goggles or other protection recommended by the manufacturer. Never
overreach especially when on a ladder.
| Avoid power lines. Contact can cause serious injury
or death. |
| | | | | | | | | |
Use these accident-prevention techniques:
| Keep your equipment in good operating condition.
| Blocked snow or leaf blower: Unplug the power cord
for these electric appliances (or turn the engine off for
gasoline-powered products) before attempting to clear the
obstruction. To clear out the blockage, use a stick long enough to
protect your hands from injury. Never put your hand near the
collection or discharge chutes. Even when the engine is off, blades
can remain spring-charged, resulting in swift movement when its path
is cleared. Extra precaution is always wise. |
|
Ladders and electricity do not mix.
Electrocutions (an average of 12 over the last three
years according to the U.S.Consumer Product Safety Commission) can
happen when metal ladders are used near overhead wires to clean gutters,
paint houses, trim trees and repair roofs and chimneys or install
outdoor antennas.
| Use only a fiberglass or wooden ladder if you must
work near overhead wires and do not let it come into contact with
the wires.
| If you must use a metal ladder, keep it well away
from overhead lines.
| If a ladder starts to fall into an overhead line,
let it go! Stay nearby while someone else calls the power company to
cut off electricity to the line before you touch or move the ladder
that is in contact with a power line.
| Never touch a person who is holding a ladder that
has fallen onto a power line. Use something that does not conduct
electricity, such as a long piece of dry wood or rope to push or
pull them loose. |
| | |
BATTERY-OPERATED PRODUCTS
Follow the same safety rules with cordless,
battery-operated products as any other electrical product. Batteries
generate electric power. Read and follow manufacturers instructions.
Some special things to remember when using
battery-powered products:
| Keep batteries away from children.
| Cordless products, since they don't have to be
plugged in, are always ready to use. Store them away from children
or inexperienced persons.
| Bring cordless products indoors overnight so they
wont be subjected to a higher moisture level or a sudden rainstorm.
| Remove batteries or lock switches in
"off" position when not in use before changing accessories
or cleaning battery-operated products to prevent accidents while
your hands are near blades or other moving parts.
| All batteries should be replaced at the same time.
Do not mix fresh and discharged batteries or battery types.
| Ensure batteries are installed correctly in device
and charger with regard to polarity (+ and -).
| Do not use cordless tools near gaseous or explosive
materials. Sparks from their motors might cause fires or explosions.
| Never short circuit
batteries as this may lead to high temperatures, leakage or
explosion.
| Never attempt to disassemble batteries as this can
lead to electrolyte burns. |
| | | | | | | |
Things to remember when recharging batteries:
| Always recharge battery-operated products with the
charging unit and procedure recommended by the manufacturer.
| Recharge products in a dry place away from
radiators, heaters, stoves, flames or chemicals.
| Plug charger directly into an electrical outlet,
never into an extension cord.
| If your product battery does not recharge properly,
first check the trouble section of your instruction manual. Next,
take the product and the charger to a manufacturer-recommended
repair center.
| Replace batteries only with recommended size and
type to insure compatibility between rechargeable battery and
charging circuit.
| Never attempt to recharge primary batteries as this
can cause them to leak, cause a fire or explode. |
| | | | |
Take these precautions with extra batteries:
| Do not expose batteries to moisture, frost or
temperatures over 110 degrees or under 20 degrees F. Do not store in
refrigerator or freezer. If batteries get cold; bring them to room
temperature before use.
| Do not store batteries touching metal objects such
as wire, nails or coins (in your pocket). Such contact can cause a
large current flow, possibly leading to burns or fire. |
|
And for safe battery disposal:
Batteries and battery packs can explode in a fire.
Follow manufacturers instructions for disposal.
POWER TOOL SAFETY
Power tools are often used out of doors or in a garage
or shed where the door should be open for adequate ventilation,
especially when sanding. The same rules apply to them as to other
electrical products used outdoors and then some. Power tools require
skilled use. Operators should not only read but also memorize the
product instruction manual.
Power tools should never be used when children are in,
or even near, the work area.
Power tools should always be:
| Held by the insulated gripping surface to avoid
electrical shock.
| Used with safety goggles and other safety gear: a
face shield, dust mask, hard hat, ear protection, gloves or safety
shoes as recommended by the manufacturer.
| Used with a GFCI, either permanently installed or a
plug-in type.
| Plugged into a three-pronged outlet known to be grounded,
unless they are double insulated. Used with a three-wired extension
cord, if needed.
| Used in a dry area away from explosive fumes
(gasoline or naphtha), dust or flammable materials. |
| | | |
Power tools should never be:
| Used while wearing loose clothing or jewelry that
can get caught in a moving part.
| Used near live electrical wires or water pipes,
especially when cutting or drilling into walls where they could be
accidentally touched or penetrated.
| Used after they have tripped a safety device such
as a GFCI. Take the tool to a manufacturer-authorized repair center
for service.
| Used when you are upset, angry or in a hurry.
| Used without guards or with an extension cord
longer than 100 feet. |
| | | |
Other outdoor electrical products such as fans, bug
killers, holiday or party lights, heaters, music systems, power paint
rollers, barbecue spits and many more each have manufacturer-recommended
precautions included in the instructions that are packaged with them.
Take time to read and follow instructions. Here are a few reminders:
Power washer-This product uses water
with electricity. Make sure you read the directions carefully.
Barbecue grill-Read directions to
find out if it can be stored outdoors or used on an apartment balcony,
patio or deck. Also check with your apartment building manager for usage
rules and/or local ordinances or regulations.
Charcoal igniter-Do not store
outdoors.
