OCEANSIDE, Calif. – A fire from a metal pile in an Oceanside scrap yard Monday threw off thick plumes of black smoke high into the air, but the blaze was contained to the property, firefighters said.

At 7 a.m., multiple 911 calls were placed about the fire burning inside a metal recycling business at 1030 W. Airport Road, north of state Route 76, the Oceanside Fire Department said in a news release. The first units arrived within minutes and found a large pile of metal, containing a mix of recyclable household appliances and iron and aluminum equipment, burning on the property.

Firefighters set up from a distance and established hose streams to ensure it would be contained from burning off the property to adjacent businesses or a nearby hillside, the agency said. They knocked the fire down and then used “a combination of diking techniques” to limit potential runoff hazards.

It took roughly eight hours for the fire to be completely extinguished by Oceanside firefighters with the support of other agencies, including the Camp Pendleton, Carlsbad and Vista fire departments.

No injuries were reported and no structures were damaged by the blaze, firefighters said.

The cause of the fire remains under investigation
