In December 2009, a 33 year old male fire fighter died and eight fire fighters, including a lieutenant and a junior fire fighter, were injured in a dumpster explosion at a foundry in Wisconsin. At 1933 hours, dispatch reported a dumpster fire at a foundry in a rural area. Eight minutes later, the initial responding crews and the incident commander (IC) arrived on scene to find a dumpster emitting approximately two-foot high bluish green flames from the open top and having a ten-inch reddish-orange glow in the middle of the dumpster’s south side near the bottom. The IC used an attic ladder to examine the contents of the dumpster: aluminum shavings, foundry floor sweepings, and a 55 gallon drum. Approximately 700 gallons of water was put on the fire with no affect. Approximately 100 gallons of foam solution, starting at 1 percent and increased to 3 percent, was then put on the fire, and again there was no noticeable effect. Just over twelve minutes on scene, the contents of the dumpster started sparking then exploded sending shrapnel and barrels into the air. The explosion killed one fire fighter and injured eight other fire fighters, all from the same volunteer department.
