Abstract: On June 30, 2009, a handyman was employed at a paper mill plant. He was operating a Bobcat and drove to one side of the plant to assist in unloading a truck. As he returned, he drove over a concrete bump in the containment area where sodium chlorate was unloaded from rail cars. The bump was approximately 10-in.-high. It was believed that the bucket on the Bobcat made contact with the concrete bump creating a spark, which subsequently started a flash fire. The handyman was engulfed in the flames and needed assistance in putting the fire out. The worker was airlifted to a nearby hospital for treatment, where he died three days later.
