Tips on dealing with a range of
emergency situations, from working safely with standby
generators to coping with the aftermath of floods.
Downed Wires. High winds or
lightning may blow over power poles and down wires.
Electrical Safety During a Flood.
If your home or business has been flooded, electrical
hazards may exist long after the water dissipates.
Standby Electrical Generator Safety.
When a power failure does occur, a properly sized and
well-maintained standby generator can be a life saver.
Downed Wires
If you happen to be in your
vehicle in a storm when lightning or high winds cause an
electric wire to fall on your car; your first instinct may
be to leave the car.
Wait!
Try to drive the car away from
the scene if you can. If this is not possible, and if there
is no immediate danger; stay in the vehicle until
professional help arrives to rescue you.
The car is grounded: you are
safe as long as you remain inside.
Warn anyone outside of the car
not to touch it.
If you must leave the car, do
not touch the vehicle and the ground at the same time. Hop,
with feet together as far away from the car as possible--
don't simply open the door and step out. Before you jump,
make sure there is no electric wire in the area where you
plan to land. Remember too, if it's raining or wet,
electricity can travel through water so jumping into a
puddle could be dangerous.
When you jump, try to break your
fall by keeping your knees bent, then roll when you hit the
ground.

Electrical Safety During a Flood
If your home or business has
been flooded, electrical hazards may exist long after the
water dissipates. Even if water is not visible in a
building, the interior structure may be soaked and still
present an electrical hazard. Do not enter flooded basements
or buildings that may contain energized electrical wiring or
electrical appliances.
Before re-entering the premises,
contact Manitoba Hydro to ensure it is safe to do so. Have a
qualified electrician inspect all wiring before turning
power on.
If your basement floods, do not
attempt to turn off the main power switch. Notify Manitoba
Hydro to disconnect power at the pole. Stay clear of
anything that could conduct an electric current such as
metal pipes, metal ladders, and even damp wood.
Note that there is no charge for
flood-related electrical services performed by Manitoba
Hydro for customers residing in our inspection jurisdiction.
Electrical Cleanup Procedure
-
The main electrical panel
must be cleaned, dried, and tested to ensure the
integrity of the insulation.
-
Circuit breakers that have
been submerged must be replaced. Any circuit breaker
removed after being submerged must be destroyed because
it may not operate safely.
-
Replace all high limit
protection devices in heating equipment that has been
submerged such as electrical furnaces and hot water
tanks.
-
Replace all devices such as
receptacles and switches that have been submerged in
flood water.
-
Do not use any
appliance, heating, pressure, or sewage system that has
been subjected to flood water until the electrical
components of the appliance or system have been
thoroughly cleaned, dried, and inspected by a qualified
electrician.
-
Before turning on the power,
have a qualified electrician inspect all wiring that has
been subjected to flood water. Even if your basement did
not suffer water damage, the interior structure may be
soaked and can still be a good conductor of electricity.

Standby Electric Generator
Safety
Unavoidable events such as ice
storms, high winds, equipment failures, and accidents can
create power failures.
This risk is particularly high
in rural areas because of the greater distance between
consumers, resulting in more miles of electrical
distribution lines being exposed to severe weather and other
hazards.
When a power failure does occur,
a properly sized and well-maintained standby generator can
be a life saver. Electricity can be restored within minutes
with a manual start generator, or in seconds with an
automatic-start unit, allowing normal activities to
continue.
Safety Tips for Portable
Generators
-
Portable standby generators
for urban or rural homes generally range from 4 000 - 12
000 watts.
-
Here are some key safety
tips to follow if you have one of these units:
-
Never operate a generator in
your house, garage, or other enclosed building. Carbon
monoxide is a colourless, odourless, and deadly gas.
-
Good ventilation for your
generator is critical, since overheating will damage the
generator and render the warranty invalid.
-
A typical 3500 watt
generator burns about 2 litres of fuel an hour at full
load.
-
Note that stored fuel
creates a fire/explosion hazard. Under the National Fire
Code, only 5 litres may be stored in a residential
dwelling, or 30 litres in a garage/shed. Call your local
Fire Department for requirements in your area.
Safety Tips for Larger Standby
Generators
Larger standby generators
usually develop 8 000 watts or more. They are engine driven
or tractor driven (using the power take-off or PTO on the
tractor), and may have automatic or manual starting systems.
Here are key safety tips for
operating these generators:
-
Keep all guards and shields
in place to protect the operator from moving parts.
-
Never shut off the generator
when under load.
-
Following severe weather,
always check for downed wires. Running a generator could
energize them.
-
Always repair or service
your generator with the engine stopped and the starting
system disabled.
On an automatic start generator, this means locking out
the switch gear and automatic transfer switch on the
generator you are repairing or servicing. This makes
sure that the generator does not try to start if an
outage occurs when you are doing your work.
-
Before you service a
generator driven by a PTO , turn off the tractor and
disconnect the PTO.
-
On PTO driven units, always
set the tractor brake before starting the generator.
-
Use extreme care in wet
conditions. The output voltage of a generator can cause
a fatal electric shock.
-
Treat the output cables or
terminal box wiring of a generator with respect. They
have the potential to kill you or a family member.
-
Do not allow a child or
unqualified person to operate or connect the generator
to any circuits.
-
Never store fuel near the
generator, unless you are using a proper container or
fuel tank. Note that stored fuel creates a
fire/explosion hazard. Under the National Fire Code,
only 5 litres may be stored in a residential dwelling,
or 30 litres in a garage/shed. Call your local Fire
Department for requirements in your area.
-
Never re-fuel a generator
when hot, or while the engine is running.
