FEMA: Use Generators Safely at Home

DR-4611-LA FS 004

Generators are emergency equipment that provide a secondary source of power when
there is an electric failure. Many survivors in Louisiana are using portable generators
because of power failure in the wake of Hurricane Ida. Generators can be helpful during a
power outage, but they present serious health and safety concerns.

Be Aware of Hazards
▪ Carbon monoxide poisoning
▪ Fire
▪ Electrocution

Safety Tips
▪ Be sure to read the manufacturer’s instructions on how to use the generator.
▪ Carbon monoxide poisoning
o Do not assume that you are safe. Carbon monoxide from generators is completely colorless and odorless, so
you won’t know if it’s there. It could kill your family and your pets.
o Do not use a generator indoors or in partially enclosed spaces- including homes, garages, and crawl spaces –
even those areas with partial ventilation.
o Do not operate near open doors and windows. Using fans will not prevent carbon monoxide build-up in the
o Install battery-powered carbon monoxide alarms inside your home to alert you of dangerous levels. Be sure
to follow the manufacturer’s recommended placement.

 Electrocution or electric shock
o Always connect the generator to appliances with heavy-duty extension cords.
o Hooking up your generator directly into your home power supply could increase the voltage or could cause a
surge to the outside power lines and potentially injure or electrocute an unaware utility lineman. It also
bypasses some of the built-in household circuit protection devices. Connecting the generator to your home
could cause a surge in electricity that might result in injury or death to yourself or your family.

o Use a qualified electrician to install the appropriate equipment in accordance with local electrical codes or
ask your utility company to install an appropriate power transfer switch.

o Keep your generator outside and fuel your generator outside.
o Do not store fuel for your generator in your house. Gasoline, propane, kerosene, diesel and other flammable
liquids should be stored outside living areas in properly labeled, non-glass safety containers.
o Do not store fuel near a fuel-burning appliance, for example a gas stove.
o If the fuel is spilled or the container is not sealed properly, invisible vapors from the fuel can travel along the
ground and be ignited by the appliance’s pilot light or by arcs from electric switches.
o Before refueling the generator, turn it off and let it cool down. Gasoline or other flammable liquids spilled on
hot engine parts could ignite, and invisible vapors from the fuel can travel along the ground and be ignited by
the generator’s pilot light or by arcs from electric switches in the appliance.
