Safe Use of Portable Generators

Key Hazards

• Carbon monoxide exposure from generator exhaust
• Electric shock from damaged cords or wet conditions
• Fire or burns during fueling
• Improper connection to building wiring
• Overloaded circuits or undersized extension cords
• Noise, hot surfaces, and trip hazards around the generator

2–3 Minute Talk Script

Portable generators are useful during temporary power needs, outages, and field work, but they create serious hazards if they are placed, fueled, or connected incorrectly.

Carbon monoxide is one of the biggest generator hazards. Generators should never be used indoors, in garages, in enclosed spaces, or near air intakes, doors, or windows where exhaust can enter occupied areas.

Electrical connections should be made safely. Cords should be properly rated, in good condition, and protected from water, damage, traffic, and sharp edges.

Generators should not be connected directly to building wiring unless the proper transfer equipment is installed and used by qualified personnel. Improper connection can backfeed power and endanger workers or utility crews.

Fueling should be done carefully. The generator should be shut off and allowed to cool when required before fuel is added. Spills should be cleaned up before restarting.

Wet conditions increase shock risk. Generators, cords, plugs, and connections should be kept dry or protected according to manufacturer instructions and electrical safety requirements.

Generators can be loud and have hot surfaces. Workers should consider hearing protection, burn hazards, exhaust direction, and safe placement away from combustible materials.

Safe generator use depends on location, ventilation, electrical protection, and fueling discipline. Keep exhaust away from people, protect power connections, and do not improvise electrical hookups.

Safety Reminders

• Operate generators outdoors and away from doors, windows, and air intakes.
• Never run generators in enclosed spaces.
• Use properly rated cords in good condition.
• Do not backfeed building wiring.
• Shut down and cool generators before fueling when required.
• Keep cords and connections protected from water and damage.
• Watch for hot surfaces, noise, and exhaust hazards.

Ask the Crew

• Is the generator placed where exhaust cannot enter occupied areas?
• Are cords and connections rated and in good condition?
• Is the generator protected from wet conditions?
• Could the generator be overloaded?
• Is fueling being handled safely away from ignition sources?
