Generator safety: Deaths from CO poisoning on the rise

Deaths from carbon monoxide poisoning associated with the use of portable generators are increasing, according to new information released by the Consumer Product Safety Commission.

There were 85 carbon monoxide poisoning deaths attributed to the use of generators in 2006, the year covered in the latest CPSC study. The estimated number of generator-related CO fatalities doubled in 2005 and 2006 from the two prior years, with a combined estimate of 182 fatalities in 2005 and 2006 compared to an estimated 92 in 2003 and 2004, the agency reported. One reason for the sharp spike in 2005 was likely a high number of severe weather events that caused widespread power outages, including hurricanes Katrina and Rita.

Non-weather related CO fatalities associated with generator use are also on the rise—by 53 percent from 2004 to 2005, and another 41 percent from 2005 to 2006. In contrast to 2005, the busiest hurricane season since records have been kept, there were no hurricanes that made landfall in the U.S. in 2006.

Recently, Underwriters Laboratories asked us to help get the word out on generator safety and to call attention to its first standard for portable generators, which took effect in March. The standard—UL 2201—addresses hazards associated with the typical use of generators, primarily those related to CO poisoning.

According to UL, the new performance requirements facilitate safe outdoor use of UL-listed portable generators during storms or poor weather conditions, as well as provide clear usage labels for consumers to help reduce the known risks of CO poisoning and electrocution.

Here are some tips on generator safety that our readers have found helpful..

• Never operate a generator indoors or in any enclosed or partially enclosed area—even if you think you can adequately ventilate the space.
• Keep generators away from windows, doors, air conditioners, and vents where gases can enter the house. Outside, always be conscious of where the exhaust gas is moving, and stay out of its path.
• Maintain working carbon-monoxide detectors throughout your home.
• Properly store and handle the gasoline. Never refuel the generator while it's running; stop the engine and allow it to cool first.
• Store gasoline safely. Keep it outside in a cool place away from the house or a heat source. Treat gas with a stabilizer (about $5 to treat 25 gallons) to preserve it for up to a year. And dispose of old fuel by using it in mowers and other outdoor equipment.
• Be sure the generator is properly grounded, and use extreme caution around wet electrical cords. Use a portable GFCI device with extension cords whenever you use your generator.
• Never connect a generator directly to a home's wiring. If the generator is used to power home circuits, always use a properly installed transfer switch (about $600 installed).
• Keep connections safe. For small generators, use extension cords rated for the wattage they're carrying.
