Whenever a major weather event threatens an area, portable generators are a hot commodity at nearby stores. But it's important to know how to use them because misuse can be a deadly mistake.

In 2020, more than half of all deaths blamed on Hurricane Laura were due to improper generator use, according to NPR. Carbon monoxide deaths from improperly used generators were also reported during the February 2021 Texas cold blast and other recent tropical disasters.

Among the primary threats to life and safety from improper generator use are carbon monoxide poisoning, electrocution and fire. Energy.gov has a list of safety tips to remember when using a portable generator that could save your life the next time severe weather strikes:

-Position generators outdoors and well away from any structure. Running a generator inside any enclosed or partially enclosed structure can lead to dangerous and often fatal levels of carbon monoxide. Keep generators positioned outside and at least 15 feet away from open windows so exhaust does not enter your home/business or a neighboring home/business.

-Keep the generator dry. Operate your generator on a dry surface under an open, canopy-like structure and make sure your hands are dry before touching the generator. Do not use the generator in rainy or wet conditions.

-Disconnect the power coming into your home/business. Before you operate your generator, disconnect your normal source of power. Otherwise, power from your generator could be sent back into the utility company lines, creating a hazardous situation for utility workers.

-Make sure your generator is properly grounded. Grounding generators can help prevent shocks and electrocutions. Refer to OSHA guidelines for grounding requirements for portable generators.

-Plug equipment directly into the generator. Use heavy-duty, outdoor-rated extension cords that are in good working condition and have a wire gauge that can handle the electric load of any connected appliances.

-DO NOT plug the generator into a wall outlet. NEVER try to power your house/business by plugging the generator into a wall outlet or the main electrical panel. Only a licensed electrician should connect a generator to a main electrical panel by installing the proper equipment according to local electrical codes. Make sure the electrician installs an approved automatic transfer switch so you can disconnect your home’s wiring from the utility system before you use the generator.

-Maintain an adequate supply of fuel. Know your generator’s rate of fuel consumption at various power output levels. Carefully consider how much fuel you can safely store and for how long. Gasoline and diesel fuel stored for long periods may need added chemicals to keep them safe to use. Check with your supplier for recommendations. Store all fuels in specifically designed containers in a cool, dry, well-ventilated place, away from all potential heat sources.

-Turn the generator off and let it cool before refueling. Use the type of fuel recommended in the manufacturer’s instructions.

-Inspect and maintain your generator regularly. Check aboveground storage tanks, pipes, and valves regularly for cracks and leaks, and replace damaged materials immediately. Tanks may require a permit or have to meet other regulatory requirements. Purchase a maintenance contract and schedule at least one maintenance service per year, such as at the beginning of every hurricane season. Keep fresh fuel in the tank, and run the generator periodically to ensure it will be ready when you need it.
