Winter reminder: Check those detectors

As falling temperatures begin to put furnaces, space heaters and fireplaces to work, the risk for house fires and carbon monoxide leaks increases. That means it’s more important than ever to check that your home’s smoke detectors and carbon monoxide (CO) detectors are up to the task.

First, ensure your home’s smoke and CO detectors have fresh batteries. (These batteries should be replaced annually.) Next up, test each detector for proper functioning once every month. Finally, the National Safety Council advises that CO detectors should be replaced every five years and smoke detectors should be replaced every 10 years.

Following these simple guidelines can help ensure your home’s smoke and CO detectors are ready to work this winter and beyond.
