We all know that we need to check our smoke alarms to make sure they are working – but do you know how often you need to check, and do you actually test them? Smoke alarms that are properly installed and maintained can save your life. Follow these recommendations from the National Fire Protection Association to ensure you and your loved ones have time to get out of the house safely in the event of a fire.A smoke alarm should be installed in every room where people sleep, outside each separate sleeping area, and on every level of your home. You should test each alarm once a month; press the test button to be sure it is functioning properly. Make sure everyone in your home, including your children, understands the sound of the smoke alarm.Some smoke alarms come with a non-replaceable 10-year battery. These smoke alarms are designed to be effective for up to 10 years, and if the alarm chirps, you should replace the entire smoke alarm. Alarms with any other type of battery need a new battery at least once a year; if the alarm chirps, that means it is time to replace the battery. Keep the manufacturer’s instructions, and be sure to buy the brand and model of battery that they recommend – the alarm may not work properly if it doesn’t have the correct battery.For more information, please visit nfpa.org/public-education/by-topic/smoke-alarms.
