Generator Safety
Generators are a handy addition to any household
They can certainly make life easier when power disruptions occur. However, for safety, you have to take into account the added dangers that generators can bring…electrical hazards and carbon monoxide.
Shock and Electrocution
- Never attach a generator directly to the electrical system of structure (home, office, trailer, etc.) unless a qualified electrician has properly installed the generator with a transfer switch.
- Always plug electrical appliances directly into the generator using the manufacturer’s supplied cords or extension cords that are grounded (3-pronged). Inspect the cord to make sure they are fully intact and not damaged. Never use frayed or damaged extension cords.
- Keep a generator dry; do not use it in the rain or in wet conditions. If needed, protect a generator with a canopy.
Carbon Monoxide Poisoning
- Never use a generator indoors or in enclosed spaces such as garages, crawl spaces, and basements.
- Make sure a generator has three to four feet of clear space on all sides and above it to ensure adequate ventilation.
- Be cautious when using a generator outdoors to ensure it is not placed near doors, windows, and vents could allow CO to enter and build up in occupied spaces.
- If you or others show symptoms of CO poisoningdizziness, headaches, nausea, tirednessget to fresh air immediately and seek medical attention. Do no re-enter the area until it is determined to be safe by trained and properly equipped personnel.
Fire Hazards
- Generators become hot while running and remain hot for long periods after they are stopped. Generator fuels (gasoline, kerosene, etc.) can ignite when spilled on hot engine parts.
- Before refueling, shut down the generator and allow it to cool.
- Gasoline and other generator fuels should be stored and transported in approved containers that are properly designed and marked for their contents, and vented.
- Keep fuel containers away from flame producing and heat generating devices (such as the generator itself, water heaters, cigarettes, lighters, and matches). Do not smoke around fuel containers.
Noise and Vibration Hazards
- Generator engines vibrate and create noise.
- Excessive noise and vibration could cause hearing loss and fatigue that may affect job performance.
- Keep portable generators as far away as possible from work areas and gathering spaces.
- Wear hearing protection if this is not possible.
Connecting Your Home
Portable generators are not designed for powering your home’s electrical system. Connecting a generator through your house wiring can introduce new hazards for both your home and electrical workers who are restoring power.
Energizing your home wiring without proper disconnects in place can energize lines creating a major hazard for workers and for the general public who may be exposed to downed lines.
Any connection for a generator to power your home should be made by a licensed electrician to ensure that the wiring and connections are correct and that proper safety disconnects are in place.
