State of emergency declared as Boyle Heights fire continues to burn

Three days after the fire erupted at the sprawling warehouse, a large column of smoke on Saturday continued to rise into the air above Boyle Heights and drift into areas that are miles away from the scene.

"This is a very unique fire, a very unique challenge for the Los Angeles Fire Department," LAFD Chief Jaime Moore said at a morning news conference. He described the cold storage facility were the fire was smoldering as "like a giant cooler."

The structure has corrugated steel on its exterior walls, filled with "very, very dense foam," Moore said, adding that ammonia was used as a refrigerant to keep the 85 million pounds of frozen food inside the building cold. "So if you can imagine walking into a cold-storage freezer, that's really what we're dealing with here."

Helicopters have been performing water drops on the building as the foam continues to burn.

A flare-up at the Boyle Heights warehouse sent black and white smoke billowing into the air.

"We've already mitigated the hazardous materials portion but now we're starting to deal with the biohazard portion," the fire chief said, referring to the spoiling food.

He urged anyone participating in outdoor activities on Saturday, including the region's many events connected to the World Cup tournament, to be cautious if they are sensitive to smoke.

"But there's nothing in the air that is so dangerous that we have to do evacuations or even shelter-in-place," Moore said.

Nonetheless, two shelter locations were opened to support anyone affected by the fire: Pecan Rec Center at 145 S. Pecan St., and City Terrace Park at 1126 N. Hazard Ave.

"The good news is, all of our air monitoring that has been done by our department, Hazmat, LA County Hazmat, as well as AQMD, has shown that there are no additional toxic chemicals or hazards within that smoke other than normal structure fire smoke," LAFD Capt. Branden Silverman said earlier. "That said, no smoke is good smoke. We know that people are being affected by this in our city as well as LA County's jurisdiction, and we do want you to take precautions to avoid that smoke whenever possible."

Lineage, the company which owns the facility in Boyle Heights, released a statement saying that it believes the fire was sparked by contractors working on solar panels on top of the roof.

"At this time, we believe the fire began while testing was being conducted by contractors of the third-party owner of the solar array located on the facility's roof," the statement said.

The company said it is assisting the LAFD and other agencies.

LAFD Battalion Chief Nicholas Ferrari said residents can expect the fire to "ebb and flow."

"You're going to see this fire ebb and flow through different conditions of smoke," he said at a Friday evening press conference. "The smoke will go away and it'll look like we have the fire out, and then 10 minutes later it could flare up again."

A flare-up at the Boyle Heights warehouse sent black and white smoke billowing into the air.

That's why the department is relying heavily on its helicopters to hit the deep-seated fire from above.

As the investigation continues into the solar panel fire that sparked the intense blaze, crews will continue to battle the flames day and night.

"I'm more optimistic that we're going to extinguish this fire," Ferrari said. "We are a very aggressive fire department, and we are working through the clock tonight. We will not stop applying water, we will not stop fighting fire until this is extinguished."

Two emergency shelters have opened in response to the fire in Boyle Heights.

The shelters are at Pecan Recreation Center, located at 145 S. Pecan St., and City Terrace Park, located at 1126 N. Hazard Ave. Officials say anyone in need of a safe place to stay is welcome to visit either location.

"We know that this is concerning. This is inconvenient, but we are doing everything we can to end this as soon as possible, and we want everybody to be safe in the meantime," L.A. Mayor Karen Bass said at a Friday evening press conference.

Residents in the area are urged to wear masks and remain indoors.
