Two employees were working to clear land with other employees and prepping a brush pile (20 x 40 x 15 feet) to be burned. They planned to ignite the brush pile by creating a fire-line or trail with an accelerant so that the pile could be lit from a distance. After applying a gasoline-diesel mixture to the pile, one employee used a cigarette lighter to ignite the pile. Two employees suffered multiple first-degree burns to the face, ears, hands, chest, and abdomen.
