Generator Safety Tips: Carbon Monoxide and Electrical Hazards

Generators save lives during outages—but improper use can be deadly. Here's how to stay safe.

Carbon Monoxide Safety

Generators produce carbon monoxide (CO)—an odorless, colorless gas that can kill in minutes.

Portable Generator Rules

• NEVER run indoors, in garage, basement, or enclosed space
• Place at least 20 feet from any door, window, or vent
• Point exhaust away from the house
• Install battery-powered CO detectors on every floor
• If you feel dizzy or nauseous, get fresh air immediately

Standby Generator Advantage

Permanently installed standby generators are safer because:

• Installed outdoors with proper clearances
• Exhaust is directed away from the home
• No need to go outside during storms
• Professional installation ensures code compliance

Electrical Safety

Backfeed Danger

Connecting a generator directly to your home's wiring without a transfer switch can:

• Kill utility workers repairing power lines
• Damage your generator when power returns
• Start electrical fires
• Damage appliances and electronics

Always use a transfer switch—it's required by code and essential for safety.

Extension Cord Safety

If using a portable generator with extension cords:

• Use heavy-duty, outdoor-rated cords
• Match cord gauge to generator output
• Never run cords under rugs or through walls
• Keep connections dry
• Don't overload cords

Fuel Safety

• Never refuel while running—let it cool first
• Store fuel in approved containers only
• Keep fuel away from the generator and ignition sources
• Don't store gasoline indoors
• Gasoline goes stale—use stabilizer for storage

Weather Safety

• Never operate in rain or wet conditions (portable)
• Use a canopy or tent—but keep sides open for ventilation
• Standby generators are designed for all weather
• Keep the area around the generator clear of snow and debris

The Safest Option

A professionally installed standby generator eliminates most safety risks:

• Permanent outdoor installation
• Automatic transfer switch prevents backfeed
• No extension cords needed
• No refueling during storms
• No going outside in dangerous weather
