Spontaneous combustion is blamed for a debris fire at the Central Transfer and Recycling Center, 11034 N.E. 117th Ave., on Sunday morning.
Vancouver firefighters quickly tamed the smoky fire that was reported by a security firm at 6:27 a.m.
Capt. Chris Moen said the debris pile was about 4 to 5 feet high and 20 feet in circumference.
“Fire crews opened up main roll-up doors on two sides and found the building charged with heavy smoke and the sprinkler system had activated and was flowing water,” Moen said in a press release.
