Propane Left Open Overnight Led to Camper Explosion and Worker Injuries

Location: Delta

Regulated industry sector: Gas – Propane System

Incident overview

While moving a mattress, employees accidentally bumped a stove knob, turning on the gas, which was left on overnight. This allowed gas to accumulate inside the camper. When the supervisor entered the unit, fresh air mixed with the propane, creating a flammable concentration. Once the power for lighting was restored, the ignition occurred, resulting in an explosion that caused major injuries to three workers, and major structural damage.
