Scores of Los Angeles Firefighters worked tirelessly in searing late summer heat to quench flames in an apartment building Sunday afternoon.

The Los Angeles Fire Department was summoned at 1:50 PM on September 14, 2014 to 11560 Friar Street in North Hollywood, where firefighters arrived quickly to find smoke showing from the attic of a 3,122 square-foot two story residential fourplex.

Despite ambient temperatures exceeding 108°F, LAFD crews toiled in furnace-like conditions to hold the well entrenched flames in the attic of the building. During the fierce firefight, a rooftop vent structure collapsed within the structure. Though firefighters were spared injury, the roof and upstairs ceiling in the southeast section of the building were severely damaged.

Eight-eight firefighters under the command of Battalion Chief Dean Zipperman held the fire to attic, extinguishing the flames in just 46 minutes. An additional 19 Fire Department personnel later joined them on a rotating basis for the hours-long effort to overhaul smoldering debris, salvage personal property and investigate the cause of the blaze.

During strenuous emergency operations, one firefighter sustained debilitating neck, back and shoulder pain. He was taken to an area hospital in fair condition, where he was treated and released to remain off duty. Two of his colleagues who labored relentlessly at the peak of the fire were later evaluated by LAFD Paramedic for heat exhaustion, before being released to resume duties after a brief period of rest and hydration.

No other injuries were reported.

The fire displaced four adults and six children, who declined offers of assistance from the American Red Cross, choosing instead to seek their own accommodation.

The heavily damaged building sustained an estimated fire loss of $690,000 ($675,000 structure & $15,000 contents). The cause of the fire - which originated in the attic, was determined to be electrical nature.
