Investigation on the Adventist school fire concluded on April 28, according to Fricia, who added that the library was one of the main points of origin. No accelerants were used to start the fire, according to the investigation, said Fricia, noting that the library would have plenty of flammable materials - books. Having an aerial ladder truck could have helped firefighters at the scene, but probably wouldn't have stopped the building from burning down, according to Adams. With a ladder truck, the metal roof could have been ventilated. Most of the local firefighters who fought the inferno were volunteers - people with everyday jobs.
Employers pay the firefighters when they go out on calls to serve the public.
Three firefighters were injured at the fire, two with minor cuts, and one with a puncture wound to the hand. Construction to the school building started in the late '70s, and the building was first occupied in 1980. Work on fencing the school yard to keep public from the unsafe building began on April 28. Adams and Fricia commended the people from Tillamook Adventist School for their outstanding support of firefighters by giving food, drinks, and words of appreciation as their building was burning down. They were absolutely fantastic.
