Changes to Clocks, Smoke Alarm Batteries

Nova Scotians are reminded to replace the batteries in their smoke detectors when they turn back their clocks on Sunday, Oct. 29.

"If you make it a habit to regularly replace the batteries in your smoke alarms, it could save your life," said Robert Cormier, Nova Scotia's fire marshal. "Let changing the time on your clock become your reminder to also change those batteries."

Mr. Cormier recommends replacing the standard nine-volt batteries twice a year, when the time changes in the spring and fall.

"It's an easy way to remember a very important and yet simple task," he said.

When battery power is low, most smoke alarms emit a brief chirping sound.

"Homeowners should not be tempted to remove the battery to stop the chirping, while intending to replace the battery later," said Mr. Cormier. "You are taking a big risk if you do that."

New batteries should be installed in smoke alarms as soon as the old ones are removed.

The fire marshal's office recommends a smoke alarm on each level of multi-level homes and outside sleeping areas. All alarms should meet the requirements of a professional testing laboratory, such as Underwriters Laboratories.

Smoke alarms should be tested every month and replaced every 10 years.
