It’s that time of year again to change the batteries in your smoke alarms and CO detectors.

This comes as clocks are set to spring forward by one hour on Sunday. North Hastings Fire Chief Pat Hoover says this is also a good time to check their expiry dates.

Hoover says you should check the batteries and expiry dates of your smoke alarms and CO detectors twice a year, when clocks spring forward and fall back.

In Ontario, it is the law to have a smoke alarm on every floor of your home, and outside of every bedroom. You are also required to have a CO detector on every floor of your home that has a bedroom if you use wood, propane, or oil for heat, or if you have an attached garage. If your alarm goes off, Hoover says you should get out of your home immediately, get to a safe place, and call 911.

Daylight saving time starts at 2:00 a.m. on Sunday, and will end when clocks fall back on November 4th.
