Apartment Building, Residential Portland, OR – Sprinkler system credited with controlling apartment fire; No injuries reported September 15, 2016 viking210 A working fire alarm and sprinkler system helped people get safely out of an apartment complex Tuesday with a unit on fire, Portland firefighters said. When firefighters arrived at the complex at 12110 E. Burnside Street at about 10 p.m., smoke was coming from the back of a second-story unit. Firefighters said no one was injured. They said people had time to evacuate the building because the apartment’s fire alarm went off and the building’s sprinkler system put most of the fire out. Firefighters said the cause of the fire is being investigated.
