Easy and most logical answer is to make sure you have working smoke and CO2 alarms in your home. They should be checked (at least) twice a year, usually around the time when you change your clocks. If the Fire Department catches you without working alarms in your home you’re at risk of being fined $350 for each missing/defunct alarm.
Do you have an escape plan? This year’s theme to NFPW is “Every Second Counts, Plan 2 Ways Out”. Meaning, do you know two ways out of your bedroom or basement if there was a fire? Where are you meeting your family once you’re out? These are all things that everyone living in your home should know about the escape plan.
