Seattle Fire said the cause of a major fire aboard a barge in the Duwamish River was the spontaneous combustion of garbage. Once the fire was out, container were moved to facilitate overhaul operations.
A fire broke out in a stack of containers moored at Alaska Marine Lines at 5600 West Marginal Way SW shortly after 3pm on Monday drawing a huge response of 36 fire engines, a fireboat, the Coast Guard and more than 100 firefighters plus a hazmat response to the scene. Ladder trucks were called in to keep the flames and heat down as the fire appeared to be coming from the stack of containers.
Aboard the barge were cars, diesel fuel, and tanks with "residual propane" according to the Seattle Fire Department.
