Generator Safety

Warning Signs of Carbon Monoxide Poisoning

Because you cannot see, smell, or taste CO, knowing the symptoms is critical.

Symptoms may include:

  • Headache
  • Dizziness
  • Nausea
  • Fainting
  • Shortness of breath
  • Weakness

If you notice symptoms, move to fresh air immediately and call 911.

Do not attempt to shut off the generator before evacuating. Re-entering the space could increase your risk of poisoning.

Electrical & Fire Hazards of Operating a Generator

Operating a generator in wet conditions increases risk of shock or electrocution.

Electrical Safety Tips

  • Keep the generator on a dry surface
  • Dry your hands before touching the unit
  • If necessary to operate in wet weather, protect the generator per the manual—but never run it indoors to keep it dry
  • Never backfeed by plugging the generator into a wall outlet

Extension Cord Guidelines

  • Use heavy-duty, outdoor-rated cords
  • Wattage rating should exceed total appliance load
  • Ensure cords are long enough to place the generator safely outside
  • Cords must be free of damage and have all required prongs
  • Protect cords from pinching or crushing

Fuel Handling Tips

  • Store fuel in labeled, non-glass safety containers
  • Keep fuel away from the home and any fuel-burning appliances
  • Turn off generator and let it cool for two minutes before refueling
How to Properly Operate a Generator

Carbon monoxide (CO) from generator exhaust is deadly — always operate your generator outdoors.

Safety Steps

  • Read and follow the operator’s manual
  • Place generator outside, far from windows, doors, and vents
  • Never use indoors or in partially enclosed spaces
  • Install CO detectors/alarms in your home

Safely Installing a Generator

Before Installation:

  • Follow all manufacturer instructions and local building codes
    Pay attention to placement and electrical connections

Never connect a generator to your home’s electrical system without a proper isolation device. Improper installation can lead to carbon monoxide poisoning, electrocution, or fire.

This applies to:

  • Portable generators
  • Stationary units

Contact a qualified electrician to install an isolation device. Without one, your generator could harm utility workers or damage your property.
