Not all smoke alarms created equal
Date:4/11/2008

Seattle, WA---If you thought all smoke alarms were equally effective, think again. According to a recent study by researchers from the Harborview Injury Prevention and Research Center (HIPRC) and the University of Washington in Seattle, photoelectric smoke alarms are much more likely to remain functioning after installation than are ionization alarms. Ionization alarms are the most common type found in U.S. households.

The study, which looked at more than 750 households in Washington State, found that nine months after a smoke alarm was installed, 20% of the ionized alarms did not function, compared to just 5% of the photoelectric alarms. Researchers checked the same alarms six months later and found similar results. The most common cause of a non-functioning alarm was the removal or disconnection of the battery.

Researchers found that ionization detectors were more prone to nuisance alarms, often caused by cooking. Nuisance alarms are the most cited reason by residents for removing or disconnecting an alarm battery. Many fires in the house start in or around the kitchen, so we know that it is critical to have functioning smoke alarms on the first level, adjacent to the kitchen, said Dr. Beth Mueller, the study principal investigator and epidemiologist at the HIPRC. Clearly, photoelectric detectors performed much better in this part of the house.

Alarms sold for home use in the U.S. are ionization, photoelectric, or combination designs. Photoelectric and ionization alarms operate differently. While both detect particles from combustion, photoelectric alarms use optical sensors and are more sensitive to slow, smoldering conditions. Ionization alarms are responsive to flames by detecting particles from rapid combustion.

The study results are significant, said Dr. David Grossman, a pediatrician and study co-investigator who is now medical director for preventive care at Group Health in Seattle. Though the U.S. has made great strides in getting these life-saving smoke alarms in peoples homes, we still have a long way to go to make sure that they remain operational. Photoelectric alarms may be a key answer to providing longer term protection.
