Daylight Saving Time is from the second Sunday of March (March 14 this year)
This is also the best time to replace the batteries in your smoke alarms and carbon monoxide detectors.
If your smoke alarm, or carbon monoxide detector is over 10 years old it is recommended that they be replaced. They have a life span of about 10 years.
This is also a good time to get into the habit of testing your smoke alarm on a regular basis.
A candle will smolder after it is blown out. This smoke should activate the smoke alarm if placed directly below it.
REMEMBER; Only WORKING smoke alarms save lives!
Test YOUR smoke alarms and carbon monoxide detectors to-day.
Remember smoke alarms are now required on every floor level as well as outside sleeping areas.
