This weekend when you move your clocks forward for daylight savings time...don't forget to
check your smoke detectors.
The International Association of Fire Fighters is urging people to change more than just the batteries in their smoke detectors when Daylight Savings Time begins March 10. They should also upgrade their smoke detectors to make sure their homes are equipped with photoelectric smoke detectors, IAFF General President Harold Schaitberger said.

Photoelectric smoke detectors contain a light source and a light-sensitive electric cell. Smoke entering the detector deflects light onto the light-sensitive electric cell, triggering the alarm. These detectors are more sensitive to large particles given off during smoldering fires - the kind of fires that occur at night when people are asleep.
Ionization smoke detectors have a small amount of radioactive material and establish a small electric current between two metal plates, which sound an alarm when disrupted by smoke entering the chamber. But the technology leads to a delayed warning. That can lead to greater loss of life among people in a burning structure and fire fighters, who are faced with a more developed fire. A delayed warning during a smoldering fire, especially at night, can incapacitate people who are sleeping and lead to death as fire spreads. No home should be without a smoke detector, and ionization detectors should continue to be used until a home can be equipped with photoelectric detectors."
