As we turn our clocks back one hour this weekend, Sarnia Fire and Rescue is reminding us to check batteries in our carbon monoxide and smoke alarms.
Public Education Officer Mike Otis said the devices could save your life.
"It's important to have working carbon monoxide alarms adjacent to all of your sleeping areas," said Otis. "So, if all of your bedrooms are off of one hallway, you'll need a working CO alarm in that hallway. It's the leading cause of accidental poisoning deaths in North America, where 500 a year still die from carbon monoxide poisoning."
Otis said the symptoms of CO poisoning are flu-like without the fever.
He said it's the law to have working smoke and carbon monoxide alarms on every storey of the home and outside all sleeping areas.
The clocks go back one hour at 2 a.m. on Sunday as Daylight Saving Time ends.
