Smoke detectors have a life expectancy. A Nova Scotia family is sounding the alarm

A family who narrowly escaped a fire in their house in Debert, N.S., wants others to know how important it is for homes to have working smoke detectors. 

Heather Clare and her three children were forced to jump from their second-storey window to get to safety when the hard-wired smoke detector upstairs didn't warn them of a fire downstairs. 

"All the smoke detectors in the house were getting older," Clare said. "They were all 12 years old and it was only the one downstairs that went off. So it took a while for it to wake us up."

According to data shared with CBC News by the Canadian Public Safety Operations Organization, there were 18 fire-related deaths in Nova Scotia in 2021, up from seven in 2020. 

Data from Nova Scotia's Office of the Medical Examiner shows the cause of death of 81.7 per cent of fire-related deaths since 2016 was due to some type of "inhalation injury."

In a fatal fire, the smoke detectors are often destroyed, making it impossible to tell if they were operational.

But Matt Covey, Halifax Fire and Emergency's division chief of fire prevention, said he often sees expired, disabled and ineffective fire alarms in homes.

"You don't ever want to be in that situation," Covey said. "You want to be in the situation where you're notified early."

On a morning in October last year, Clare woke up around 5 a.m. to a bedroom full of smoke. Her husband was on an overnight shift, so it was up to her to wake up her children and get them out. 

The fire had blocked off the stairs and left her with only one option. 

"I smashed out the window and told the girls and my son that we had to jump," she said. "My oldest daughter was very scared, she didn't think that she could do it. So I told her that she either had to jump or she was going to die."

They all made it out of the window, but the mother and children sustained injuries. Clare's middle child still wears a body brace due to fractures in her back.

The family lost two cats, three dogs and a litter of puppies in the fire, along with their house and everything in it. 

Clare said she didn't know smoke detectors had a replacement date of 10 years after manufacture. She believes if the upstairs alarm had worked, things would have been different.
