Maryland Blogger: When 10 years old is too old

When 10 years old is too old

When 10 years old is too old


Many homes have smoke alarms that are too old. Smoke alarms are manufactured to last 10 years. Then they need to be replaced. Working smoke alarms can provide the early warning needed to save lives.

great reminder for us all - and it is good that the batteries are now sealed and the smoke detectors must be replaced with the new ones after 10 years

This is very valuable and important information, and so glad you brought it up to everyone's attention.  We just had ours replaced.  A

Good reminder Roy Kelley there are a lot of cheapskates out there that would never replace one.

Oh my...ten years is too old for a smoke detector. This is an inexpensive way to protect your family, and like anything else around the house, it needs to be updated.

 Good morning Roy Kelley . Most folks don't give smoke detectors a second thought.
