In a joint effort with the International Association of Fire Chiefs, AAA of Michigan and Energizer batteries, the Detroit Fire Department is offering to change the batteries in the smoke detectors of Detroit residents tomorrow from 10:30 am to 6:30 pm at all 44 Detroit firehouse locations.

The battery replacement program, known as Change Your Clock, Change Your Battery, coincides with the end of Daylight Saving Time, an event that officials are using to remind residents to check and change smoke-alarm batteries.

In exchange for old 9-volt batteries, the DFD will give Detroit residents up to two new ones per household. In addition to the new batteries, which were donated to DFD by Energizer, fire safety literature provided by AAA of Michigan will be given to residents participating in the program.

Chief Lee C. Moore of the Community Relations Division is quoted as saying that 80% of U.S. home fires are caused by defective smoke alarms.
