Be sure your smoke alarm is checked, maintained, and up to date. It amazes me when I speak with someone on the phone and hear the unmistakeable sound of a chirping smoke detector in the background on the other end of the phone. Or when I visit homes and see the installation plates up there on the ceiling sans detector!
The ridiculously tiny investment of your time and money buying and maintaining a smoke detector can save your life!
