Change Your Clock, Change Your Battery on March 10

“Every second weekend in March, we turn the clocks ahead one hour. This is a good time to change the batteries in our smoke and carbon monoxide (CO) alarms,” said State Fire Marshal Stephen D. Coan. “So far this winter there has been an unusually high number of fatal fires and winter is not over yet. Making sure the smoke and CO alarms are working is a simple, effective way to protect your family,” said Coan. Coan added, “Remember that on Sunday, March 10, when you Change Your Clocks, Change Your Batteries.


“Working smoke alarms can double your family’s chance of surviving a fire and when combined with a practiced home escape plan, the chances are greater,” said Coan. “Many smoke alarms and carbon monoxide alarms in our homes either run on battery power or have a battery back-up in case the power fails,” said Coan. Not all smoke and carbon monoxide alarms use batteries, but many do. Some smoke alarms have a 10-year lithium battery that only needs to be changed once a decade.


Coan said, “When you change the batteries on your home fire safety devices this year, inspect the alarms and check the date of manufacture. All electronic devices have a limited life span, so it is important that you replace your older smoke and carbon monoxide alarms with new ones to protect your family.”


Smoke alarms need to be replaced every ten years. If your smoke alarm is ten years old or older, it is time to replace them! Carbon monoxide alarms need to be replaced every five or seven years, depending on the manufacturer. Check for a date of manufacture on the back of the device, or consult the manufacturer’s instructions for the recommended replacement date. If you can’t tell how old they are, it’s time to replace them.
