You Don’t Have a Smoke Alarm
Whether a fire is caused by an electrical problem or something else, not having a smoke alarm is one of the most serious safety issues in any home. According to the National Fire Prevention Association, nearly three out of every five home fire deaths occur in homes that do not have a smoke alarm.
If the property has a working smoke alarm, the risk of dying in a fire is reduced by 55%. If you already have a smoke alarm, you should replace it every 10 years (or 7 years if you have a combination of carbon monoxide/smoke alarms) based on the manufacture date shown on the back label.
