Daylight-saving time begins on Sun., March 8 this year, and changing clocks is a good reminder to change the batteries in smoke alarms, according to the Ventura County Fire Department.

Smoke alarms save lives, but they must be properly installed and in working order to do that.

The U.S. Fire Administration reported that between 2000 and 2004, 65 percent of deaths in home fires occurred in homes that either had no smoke alarms or had alarms that weren't working.

Keeping fresh batteries in smoke alarms can save lives, but there are other ways to make sure the alarms are working efficiently:

•Replace smoke alarms every 10 years. Aging alarms don't operate as efficiently and are frequently responsible for "nuisance" alarms.

•Test units at least once a month. Use the "test" button on the device or an approved smoke substitute. Never use an open flame.

•Periodically clean smoke alarms by following the manufacturer's instructions.

•Place smoke alarms outside each sleeping area and on each level of the home, including the basement. An alarm in the garage is a good idea as well.

•Alarms should be mounted on the wall 4 to 12 inches from the ceiling. Ceiling-mounted alarms should be placed 4 inches from the nearest wall. On a vaulted ceiling, mount the alarm at the highest point of the ceiling.

•Make sure everyone in the household knows the sound the alarm makes and what to do if they hear it.

•Have an escape plan for the home and designate a meeting place outside the home to account for family members in the event of an emergency.

•Never "borrow" smoke alarm batteries or disconnect them from the device.

•Never paint a smoke alarm.
