The investigation into the cause of Wednesday’s house fire on Cartier Street continues.

Fire Chief Jason Whiteley says the Fire Marshal’s Office was notified and an investigator will be on the scene today (Thursday).

He says some occupants were taken to hospital with smoke inhalation, but things could’ve been much worse.

“If we didn’t have working smoke alarms and with the speed of the fire we would probably be looking at one or more fatalities and definitely serious injuries,” he says.

Whiteley says the fire was fully involved when they arrived on the scene, having already blown out the windows when they got there.

He also says with the clocks changing this weekend now’s the time to change the batteries in your smoke alarm, but that’s not all.

“Smoke alarms have a working life. People should double check when your smoke alarm was manufactured and when it should be replaced. People shouldn’t go more than 10 years without replacing it. It’s pretty cheap insurance,” he says.

There’s no word on a damage estimate with yesterday’s fire, as yet, but officials previously said it was a “substantial” fire.
