The Kalamazoo Fire Marshal is investigating after an explosion at a business ignited a truck with chemicals inside. Kalamazoo Public Safety says an employee at a business on Davis Creek Court was refueling a power washer when the explosion happened. The explosion then started a fire aboard a nearby box truck. Police tell us the truck ignited because the truck had flammable chemicals on board. They did not specify as to what kind of chemicals they were. When police and fire responders got to the scene, they were met with flames shooting out of the truck’s cargo area. They were able to contain the fire with a standard approach, but had to use a combination of water and special extinguishers to fully extinguish the flames.
