## Narrative

An employee was gassing up a furnace and attempting to light the pilot using a wand (igniting device). During a previous shift, one of the furnace's two gas valves was left open. When the employee began the start-up process, he opened the main gas valve without noticing that the other valve was already open. The front door on the furnace was open and a flash fire occurred, causing burns to his hands and forearms.
