July 21—Seattle Fire Investigators determined a fire in a Fremont Laundromat was caused by an exothermic chemical reaction initiated by the clothes dryer and heat.
At 2:00 a.m. a 911 call came into dispatchers at the Fire Alarm Center reporting flames visible from a commercial Laundromat located near the intersection of Fremont Avenue North and North 43rd Street. When Engine Company 9 arrived they found flames inside the 1-story commercial building. Crews made forcible entry into the business and were able to confine the fire to a west wall and a small portion of the ceiling. Within 9 minutes of arriving, firefighters had the fire under control. It took less than 20 minutes to completely extinguish the flames.
The fire investigator determined the cause of the fire was spa towels with oils that when heated caused a spontaneous combustion.
The damage estimate is $10,000.
There were no injuries.
