No injuries were reported from the fire Wednesday night, which occurred in the company's biomass boiler plant. Fire investigator Michael Martin says Frito-Lay employees tried to douse the fire themselves for several minutes before calling for help. He says the fire started in the boiler fuel hopper system and is considered accidental. Martin says production continued at the plant because the fire was in a separate building.
