LAWRENCE, MA - Lawrence firefighters arrived to find heavy fire showing from a large two-and-a-half-story, wood-frame, multi-family dwelling, March 22nd. Command quickly struck a second-alarm, bringing in mutual aid to the scene and to cover. Due to the heavy volume of fire, companies were forced to go defensive and command struck a third-alarm. Multiple ladder pipes and big hand lines were used to knock down the heavy fire and keep it from extending into the exposures. Companies remained on scene for several hours checking for hot spots.
