Portable generators are useful when temporary or remote electric power is needed, but they can be
hazardous. The primary hazards to avoid during use are carbon monoxide poisoning, electric shock or
electrocution, and fire.
TO AVOID CARBON MONOXIDE HAZARDS:
• Always use generators outdoors, away from doors, windows, and vents.
• NEVER use generators in homes, garages, basements, crawl spaces, or other enclosed or partially
enclosed areas, even with ventilation.
• Follow manufacturer's instructions.
• Install battery-operated or plug-in(with battery backup)carbon monoxide(CO)alarms in your home,
following manufacturer's instructions.
• Test CO alarms often and replace batteries when needed.
TO AVOID ELECTRICAL HAZARDS:
• Keep the generator dry. Operate on a dry surface under an open, canopy-like structure.
• Dry your hands before into generator or use a heavy-duty outdoor-rated extension cord that is free of
cuts or tears and the plug has all 3 prongs, especially a grounding pin.
• NEVER plug the generator into a wall outlet. This practice, known as backfeeding, can cause an
electrocution risk to utility workers and others and served by the same utility transformer.
• If necessary to connect generator to house wiring to power appliances, have a qualified electrician
install appropriate equipment. Or, your utility company may be able to install an appropriate transfer
switch.
TO AVOID FIRE HAZARDS:
• Before refueling the generator, turn it off and let it cool. Fuel spilled on hot engine parts could ignite.
• Always store fuel outside of living areas in properly labeled, non-glass containers.
• Store fuel away from any fuel-burning appliance.
