If an emergency were to ever happen at your home, you expect your smoke detectors to go off and alert you to the danger.
Officials say it is important to check smoke detectors in your home monthly because they will significantly increase your chances of surviving a fire.
Each day in the U.S., an average of seven people die in house fires. Officials say having smoke detectors can significantly increase your chances of survival if a fire happened.
But what if you detectors aren't working properly? Would you know how to check to see if they are?
"Like any machine, it's working 24 hours a day 7 days a week, 365 days a year," said Roy Grimmett, a volunteer with the American Red Cross. "The longer they are up there, they are a simple machine. They degrade over time."
