Safely using generators is key to reaping their benefits

Thursday, May 14, 2015

Some Oklahomans could be using generators in their recovery efforts after early spring severe storms and flooding. But, generators also can be hazardous to your health if used improperly.

“The main concerns with portable generators are carbon monoxide (CO) poisoning, electric shock and fire,” said Gina Peek, Oklahoma State University Cooperative Extension housing and consumer specialist.

In fact, most incidents reported to the Consumer Product Safety Commission involve CO poisoning from using generators in enclosed or partially enclosed areas. CO is an odorless, colorless and potentially deadly gas.

Generators should only be used outdoors and well away from any air intakes to houses or other structures, Peek said.

“Fumes can overwhelm you within minutes, even with fans or open doors and windows,” she said.

There also is a risk of shock or electrocution if a generator is used incorrectly, especially when it is wet. If the generator must be used in wet conditions, one way of protecting it from moisture is to use an open-sided canopy-like structure on a dry surface that blocks water from pooling underneath it.

Meanwhile, appliances should be connected to the generator with only heavy-duty extension cords designed for outdoor use, said Scott Frazier, OSU Cooperative Extension energy management specialist.

“Check the wattage rating on each cord to be sure it’s more than the combined wattage of all equipment connected to it, including starting wattages,” Frazier said. “Also, do not string multiple cords together much past 50 feet.”

Homeowners should avoid attempting to power home wiring by plugging a generator into a wall outlet. This dangerous practice, also known as backfeeding, increases the risk of electrocution for utility workers and neighbors using the same transformer.

“To decrease fire hazards related to using generators, flammable materials such as gasoline, propane and kerosene should be stored outside living areas and other structures,” she said. “Flammable materials also should be kept away from fuel-burning appliances such as natural gas water heaters.”

Use nonglass safety containers to store flammable materials and be sure the containers are clearly labeled.

Because gasoline spilled on a hot engine could ignite, generators should be turned off and allowed to cool before refueling.
