At 3:40 a.m. on November 29, 1988, the Kansas City, MO Fire Department received an alarm indicating there was a fire at a highway construction project. The dispatcher directed Pumper 41 to respond to the truck fire. He added: “Pumper 41, use caution on your call. There’s information there may be explosives. It’s in a construction area…” Pumper 41 arrived at 0346 and found two separate fires, one involving a pickup truck and the other involving a trailer. There was another trailer parked less than 100 feet away. Pumper 41 requested another pumper. The second pumper arrived at 0352 and began to fight the fire involving the trailer. The first company extinguished the fire in the pickup truck and proceeded to the other fire to assist the second company. At 4:08 a.m. a catastrophic explosion occurred. All six firefighters assigned to both companies were killed. Approximately 40 minutes later, a second explosion occurred, followed by several minor explosions.
