Apartment Building, Residential Portland, OR – Sprinklers halt spread of fire caused by crafting heat gun October 12, 2015 viking210 The fire caused by a crafting heat gun set on a hardwood floor by a resident damaged a Northwest Portland apartment building Sunday morning. No one was hurt in the fire, which was slowed by the building’s sprinkler system before firefighters arrived. According to Portland Fire & Rescue, at approximately 8:40 a.m. on Oct. 11, Portland Fire Engine 3 was dispatched to the report of a fire alarm at 1420 N.W. Lovejoy St. When the engine arrived, a resident of one of the apartments met firefighters outside and reported that one of the units was on fire. After circling the block to check out the building, firefighters noticed smoke coming from a second-story window. The commanding officer then upgraded the incident to an apartment fire, balancing the incident to the appropriate number of responders to handle it. Once crews entered the building, they found that the alarm system had activated and the sprinkler system was flowing. Interior fire attack crews made entry into the apartment and reported that the sprinklers had slowed the forward progress of the fire.
