As long as you’re home, it might be a good time to check your carbon monoxide detector.

Oak Harbor Fire Chief Ray Merrill said firefighters responded to five false carbon monoxide alarms over the past weekend due to the gadgets coming to the end of their manufactured lifespan.

The department also received false carbon-monoxide-related calls the week before.

The devices last from seven to 10 years and then their sensors start going bad.

To alert people, they start beeping intermittently and the worried residents call the fire department.

Merrill said this may start happening more and more unless people replace their older carbon monoxide detector alarms. It’s especially problematic during a time of mandatory social distancing.

Carbon monoxide is an odorless and deadly gas that is the product of incomplete combustion, Merrill said.

Wood stoves are notorious for producing carbon monoxide, but it can also come from things like a furnace with a hole in its heat exchanger.

Carbon monoxide alarms cost as little as $20 at places like Home Depot or through Amazon and are easy to install.
