In winter 2026, a small gas explosion and fire occurred in a Dawson Creek home, causing two workers to sustain burns. The incident also damaged a furnace, hot water heater, and the home’s interior.
Two (2) unqualified workers were disconnecting gas piping while the gas supply was still on in order to remove a furnace from a tight space. They tried to stop the gas flow by pressing their thumb against the pipe in order to fit a cap on it, a risky practice known in the industry as “live capping.” Although this method is sometimes used in the gas and plumbing field, it’s not allowed under the gas installation code. Unfortunately, the gas was ignited by the nearby water heater’s pilot light, causing injuries and damage.
One laborer quickly ran outside to shut off the gas at the meter, while the other helped the occupant evacuate the home. Technical Safety BC’s investigation revealed that both laborers worked without supervision from a certified journeyperson on site and were unqualified to perform regulated gas work.
In an occupied fully detached dwelling, a damaged gas furnace was being decommissioned to allow for installation of a replacement unit later that day. The damaged furnace and a gas-fired water heater were located close together in a small
hallway enclosure inside the residence. Two unsupervised laborers began preparing the furnace for removal while the gas supply remained on. During this work, the laborers disconnected the appliance shut-off valve and removed the gas supply riser, resulting in the uncontrolled release of natural gas into the immediate work area. The escaping gas was subsequently ignited by the standing pilot light on the water heater, which was situated directly next to the furnace. A small explosion and localized fire followed. The fire was confined to the appliances and the surrounding wall area. Both laborers sustained burns during the Incident.
