ATLANTA — Carbon monoxide poisoning from portable generators is one of the most common causes of disaster-related deaths in the days following a major storm or power outage — a preventable tragedy that kills dozens of people every year despite widespread public awareness campaigns.
Carbon monoxide is a colorless, odorless gas produced by the incomplete combustion of fossil fuels. Portable generators, pressure washers, and other gasoline-powered equipment produce large quantities of carbon monoxide and should never be operated indoors or in enclosed spaces, including garages, basements, and crawl spaces.
The CDC reports that portable generators cause approximately 70 deaths per year from carbon monoxide poisoning, with the majority occurring in the days following major storms and power outages. The risk is highest when generators are operated in or near the home, where carbon monoxide can accumulate to lethal concentrations within minutes.
Restoration contractors who use generators on job sites must follow OSHA's requirements for generator safety, including operating generators outdoors in well-ventilated areas, keeping generators at least 20 feet from any door, window, or vent, and installing battery-operated carbon monoxide detectors in all areas where workers are present.
Homeowners who use generators during power outages should follow the same safety precautions. Carbon monoxide detectors should be installed on every level of the home and tested regularly. If a carbon monoxide alarm sounds, occupants should immediately move to fresh air and call 911.
