A couple in Port Alberni, B.C., is crediting a carbon monoxide detector with potentially saving their lives.

The alarm, which was gifted to them by a family member, alerted the couple to the odourless gas.

"All of a sudden we heard this beeping and we all kind of hear it, but ignored it, and then we were like, 'What was that?'" said Shelly Anderson.

The beeping was the carbon monoxide detector sounding its alarm. At first, Anderson's husband, Nori, thought the device might be defective.

"Well, my husband [thought it was]," said Anderson with a laugh.

"I was immediately concerned, I always err on the side of caution," she said.

So, the couple called 911 and firefighters arrived.
