Los Angeles firefighters battled an early morning Greater Alarm Structure Fire in Boyle Heights on November 6, 2014.

Fourteen minutes after midnight, LAFD responded to 3724 Whittier Boulevard to find a one-story cinder-block tilt-up commercial building with four businesses under one roof with smoke pouring out. An aggressive interior fire attack ensued while firefighters simultaneously laddered the roof to perform vertical ventilation with chain-saws to release the hot smoke and gasses. Conditions rapidly deteriorated as flames viciously spread inside the businesses and through the attic.

All firefighters were ordered out of the burning structure and off the roof at 12:40 AM and the Incident Commander insured all members were accounted for. Firefighters then set up to utilize "Ladder Pipe Operations", placing large hose lines up aerial truck ladders to pour copious amounts of water from the exterior, inside the burning building. By 1:25 AM the bulk of the flames were extinguished and firefighters briefly made another interior attack, before they were forced outside, yet once again, due to conditions inside quickly becoming unsafe. Firefighters relentlessly battled the flames. Just before 2:30 AM they were able to safely bring hose-lines inside to extinguish hiding hotspots.

Approximately 100 Firefighters, under the command of Assistant Chief Frazeur fully extinguished the stubborn flames in 2 hours 22 minutes. No one was injured. LAFD Arson Investigators are determining the cause of this early morning blaze. The estimated damage and dollar loss is being tabulated. It was not immediately determined if there were fire sprinklers or functional smoke alarms inside.
