Portable Generator Safety
Portable generators are useful when temporary or remote electric power is needed, but they can also be hazardous. The primary hazards to avoid when using a generator are carbon monoxide (CO) poisoning from the toxic engine exhaust, electric shock or electrocution, fire and burns.
Every year, people die in incidents related to portable generator use. Most of the incidents associated with portable generators reported to the Consumer Product Safety Commission (CPSC) involve CO poisoning from generators used indoors or in partially enclosed spaces.
Carbon Monoxide Hazards
When used in a confined space, generators can produce high levels of CO within minutes. When you use a portable generator, remember that you cannot see or smell CO. Even if you do not smell exhaust fumes, you may still be exposed to CO.
If you start to feel sick, dizzy or weak while using a generator, get to fresh air RIGHT AWAY. Do not delay. The CO from generators can rapidly kill you.
Danger labels are required on all portable generators manufactured or imported on or after May 14, 2007.
Follow these safety tips to protect against CO poisoning:
- NEVER use a generator inside homes, garages, crawlspaces, sheds or similar areas, even when using fans or opening doors and windows for ventilation. Deadly levels of carbon monoxide can quickly build up in these areas and can linger for hours, even after the generator has shut off.
- Follow the instructions that come with your generator. Locate the unit outdoors and far from windows, doors and vents that could allow CO to come indoors.
- Install battery-operated CO alarms or plug-in CO alarms with battery back-up in your home, according to the manufacturer’s instruction. CO alarms should be certified to the requirements of the latest safety standards. Test batteries monthly.
To avoid CO poisoning when using generators:
- Never run generators indoors, including garages, basements, crawlspaces and sheds.
- Get to fresh air right away if you start to feel dizzy or weak.
