Many of us will be putting our clocks back an hour on Sunday, November 2. This is a good time to check your home’s alarms and change the batteries. Smoke alarms should be inspected, cleaned of accumulated dust and equipped with a new battery. Carbon monoxide alarms should get the same treatment as instructed by the manufacturer. And remember: alarms don’t last forever. They should be replaced every 10 years or so, or on a schedule recommended by the manufacturer. This is also a good time to see if your home fire extinguishers need replacement and to review the family fire escape drill.
