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 (3) workers and major structural damage. Three (3) employees approached and smelled a gas odor. One entered to investigate, and the others stayed just outside the camper.
