At 1 1:30 p.m. on June 22, 2011, Employee #1 was operating a grinder, and a pocket of hydrogen gas exploded. Employee #1 cut off a unistrut as part of a project to install hangers for processing pipe. The work was being completed next to a 300 gallon waste water tank which was being used to dump was a batch of Silicon Carbide slurry. The process being used generated a pocket of hydrogen which exploded when a spark from the grinding ignited the gas. The explosion caused a wave that split the seam of the plastic tank and pushed the tank in the direction of the employee, knocking him to the ground. Employee #1 was transported to the hospital, where he was admitted and treated for a concussion and bruised ribs.
