Complacency Cited as Cause of Gas Furnace Explosion Injuring Two Labourers
A recent incident in Dawson Creek, British Columbia, has highlighted the risks of complacency and inadequate supervision in the gas fitting industry. On January 8, 2026, two labourers suffered injuries from a small explosion during the removal of a damaged gas furnace at a residential property.
The Technical Safety BC investigation found that the labourers had disconnected the gas supply riser while the gas supply remained on, resulting in an uncontrolled release of natural gas. The escaping gas was ignited by the standing pilot light on a nearby water heater, causing a small explosion and fire.
Both labourers were considered apprentices, but no documentation confirming their registration was provided at the time of the incident. The investigation revealed that the company's owner attributed the incident to complacency stemming from a previous 'uneventful work history,' as well as informal training practices lacking clear stopping points and insufficient clarity around task boundaries for apprentices.
The company has since implemented a written policy prohibiting gas work performed by unauthorized or unlicensed personnel, ensuring it is done under proper supervision, and improving documentation, training, and oversight of safety.
