## Narrative

Injured employee was in a boom lift using a cutting torch. The worker turned the torch off and draped it over the handrail. The acetylene valve knob bumped against the mid-rail of the basket opening the valve which allowed acetylene gas to penetrate the employee's pant leg. A spark from the grinder ignited the gas causing a flash fire and burn to the worker's left leg.
