Workers were catastrophically burned while wearing uniforms provided by their employer. At the time of the fire, the workers were trying to extinguish a fire that had started in a feed bin. In the course of their efforts, a flash fire occurred, igniting the workers' uniforms. While the flash fire lasted only seconds, the uniforms continued to burn, resulting in burns over 80% of the workers' bodies. The uniforms were not flame resistant and contained no warnings or instructions concerning the risk of flammability.
