It’s time to spring ahead, and as you are always reminded to do during a time change, it’s also recommended that you change the batteries in your smoke detectors. We’ll set our clocks ahead at 2am Sunday morning, launching into daylight saving time. State Fire Marshal Tim Bean and local fire protection districts say it’s the perfect time to remind yourself to refresh your detector batteries to help prevent disaster. Three out of five deaths in residential fires occur in homes without working smoke alarms. 38% of those come from homes with no smoke alarms at all. And for good measure, firefighters say you should also change your batteries in your carbon monoxide alarms while you’re at it.
