Generator safety

Using a generator during an outage or after a storm can be a great backup until power is restored, but it’s important to use them safely. Every model is different: take time to read the instruction manual and understand how your generator works before you need it.

Run generators outside

Never run one indoors or in an enclosed space.
Run generators at least 20 feet from your home in a well-ventilated area, with the exhaust pointed away from doors and windows.
Use a battery-operated carbon monoxide detector.

Never plug into a wall

Don’t plug your generator into a wall. This can cause backfeeding—sending electricity back through the powerlines—which puts lineworkers and others at serious risk.
Never connect your generator to home wiring without an approved and properly installed device that prevents electrical backfeed.

Electrical safety

Use your generator on a dry surface under an open canopy. Don’t use it in the rain or touch it with wet hands.
Plug appliances directly into the generator, or use a heavy duty, outdoor-rated extension cord that is rated for your needs.
Check that the entire cord is free of cuts or tears and that the plug has all three prongs, especially a grounding pin.
To avoid overloads, stagger the use of large appliances.

Reduce fire risk

Turn off the generator and let it cool down before refueling to prevent fires and burns.
Store fuel in approved containers and keep them in a cool, well-ventilated area away from living spaces and the generator itself.
Place the generator on a level, nonflammable surface like gravel or concrete.
Keep it clear of dry grass, leaves or brush, and be extra cautious in dry, windy conditions.
Have a fire extinguisher ready nearby and know how to use it.
