Two Los Angeles Fire Department (LAFD) fire captains suffered from smoke inhalation and heat exhaustion after firefighters responded to a major structure fire at 8405 Pershing Drive in Playa del Rey, early Wednesday, August 31st, fire officials said.

The two fire captains were taken to Cedars-Sinai Hospital and are listed in good condition. No other injuries were reported.

Nineteen companies of Los Angeles City firefighters responded to the fire at 2:54 a.m. at the Westgate Center, a four-story office building.

One deputy fire chief, one assistant chief officer command team, six battalion chief officer command teams, two battalion supervisors and two LAFD rescue ambulances also responded.

Three arson units and one hazardous materials squad were also called to the scene.

The first fire units on the scene reported smoke coming from the fourth floor of the office building, said Jim Wells, LAFD spokesman.

Firefighters encountered heavy smoke on floor where the fire was and heat in the center hallway portion of the floor leading to the “seat” of the fire, Wells said.

Firefighters used hand lines to make an “aggressive attack” on the fire in the hallway and offices, and confined the fire to the fourth floor and attic area of the building, Wells said.

The fire was extinguished in 56 minutes, fire department officials said.

To help control and extinguish the interior fire, firefighters on the roof cut several ventilation holes through the lightweight concrete roof.

The firefighters were able to detect the progression of the fire in the attic and assist with the ventilation of heat, smoke and gases through controlled channels, Wells said.

The cause of the fire is still under investigation. Fire officials said the fire damage is still being tabulated.
