\u201cIn 2016, 17 people died in home fires where there no working smoke alarms\u201d said State Fire Marshal Peter J. Ostroskey. \u201cWe change our clocks on Sunday, November 5, so remember, when you change your clocks, check your smoke and carbon monoxide alarms,\u201d he added. \u201cSmoke alarms give us the early warning we need in the event of a fire. Not only do you need smoke alarms, but you need to make sure they are working,\u201d Ostroskey said.\n\nOne of the best things we can do as we get our homes ready for winter, is to check our smoke and carbon monoxide alarms. In a fire, time is your enemy and working smoke alarms give you precious time to use your home escape plan before poisonous gases and heat make escape impossible. A working smoke alarm is your first line of defense.\n\nReplace Aging Smoke \u0026 CO Alarms\n\nNo appliance lasts forever. \u201cWhen checking your alarms see if they need to be replaced. Smoke alarms last about 10 years and older carbon monoxide alarms last 5-7 years,\u201d said the Marshal.\n\n10-Year Alarms\n\nThere are some new smoke and CO alarms that come with a sealed 10-year lithium battery. The batteries in these alarms never need changing. You just replace the entire alarm every ten years.\n\nFor more information on smoke alarms in Massachusetts contact your local fire prevention office or go to: www.mass.gov/dfs and type Smoke Alarms in the search box.
