Firefighters Put Out Large Blaze at Commercial Building in Northridge

Authorities were able to extinguish a large fire that broke out at a commercial structure in Northridge late Thursday night, officials said.

Firefighters fought the blaze for nearly two hours after it broke out around 9:50 p.m. on the 19300 block of West Londelius Street, the Los Angeles Fire Department said in an alert. The agency had previously said the location was on Parthenia Street.

The structure, which measures 300 feet square, houses three businesses including a furniture warehouse and a printing business, authorities said. A sign on one read "Adwest Mailers," and another simply stated "Furniture Warehouse."

Officials believed two employees had been inside the building when the fire broke out but were able to escape without injury.

The flames spread to the large structure after sparking on pallets stacked in an alleyway behind the furniture warehouse, LAFD said.

The roof over the printing business — at the center of the one-story building — collapsed shortly before 10:30 p.m., sending tall flames and a column of smoke swirling into the sky, aerial video showed. Firefighters had been on the roof just before it caved.

Over 100 firefighters fought the blaze, dousing the flames with heavy streams water and conducting defensive operations, according to LAFD.

Crews would remain at the scene throughout the night.

Officials are now working to determine what led to the fire and assessing the damage.
