GRAND RAPIDS, Mich. — When severe weather hits it often times will cause damage to vital infrastructure such as the power grid or water supply. Often times, people turn to generators to restore power to their home in order to maintain use of air conditioning, heat, refrigeration units or other necessities.
While generators are helpful during these instances, they can also be hazardous. If you're going to be using a generator, it's important you know how to do so safely.
3 main generator hazards:
According to FEMA, the three main hazards when using a generator are carbon monoxide poisoning, fire and electrocution. They shared safety tips on how you can avoid each of these hazards.
Carbon monoxide poisoning:
- Do not assume that you are safe. Carbon monoxide from generators is completely colorless and odorless, so you won’t know if it’s there. It could kill your family and your pets.
- Do not use a generator indoors or in partially enclosed spaces- including homes, garages, and crawl spaces - even those areas with partial ventilation.
- Do not operate near open doors and windows. Using fans will not prevent carbon monoxide build-up in the home. Generators and fuel should only be used at least 20 feet away from windows, doors and attached garages.
- Install battery-powered carbon monoxide alarms inside your home to alert you of dangerous levels. Be sure to follow the manufacturer's recommended placement.
Electrocution or electric shock:
- Always connect the generator to appliances with heavy-duty extension cords.
- Hooking up your generator directly into your home power supply could increase the voltage or could cause a surge to the outside power lines and potentially injure or electrocute an unaware utility lineman. It also bypasses some of the built-in household circuit protection devices. Connecting the generator to your home could cause a surge in electricity that might result in injury or death to yourself or your family.
- Use a qualified electrician to install the appropriate equipment in accordance with local electrical codes or ask your utility company to install an appropriate power transfer switch.
- Keep generators dry and protected from rain or flooding. Touching a wet generator can cause electrical shock.
Fire:
- Keep your generator outside and fuel your generator outside.
- Do not store fuel for your generator in your house. Gasoline, propane, kerosene, diesel and other flammable liquids should be stored outside living areas in properly labeled, non-glass safety containers.
- Do not store fuel near a fuel-burning appliance, for example a gas stove.
- If the fuel is spilled or the container is not sealed properly, invisible vapors from the fuel can travel along the ground and be ignited by the appliance's pilot light or by arcs from electric switches.
- Before refueling the generator, turn it off and let it cool down. Gasoline or other flammable liquids spilled on hot engine parts could ignite, and invisible vapors from the fuel can travel along the ground and be ignited by the generator's pilot light or by arcs from electric switches in the appliance.
If you are using a generator make sure to follow these safety instructions and also the manufacturer's instructions very carefully.
