Firefighters are continuing their efforts to control a large blaze at a frozen-food storage facility in Boyle Heights, Los Angeles. The fire, which started six days ago, has presented significant challenges due to the building’s size and insulation.

At approximately 500,000 square feet and insulated like a freezer, the facility is across from homes in Boyle Heights, east of downtown. Smoke has been pouring from the structure, prompting city officials to advise residents to stay indoors or wear masks to avoid smoke pollution.

Complex Challenges

Fires at cold storage facilities are notoriously difficult to extinguish quickly. Jamie Stewart, spokesperson for the Los Angeles Fire Department, stated that heavy insulation in the ceilings, roofs, and walls complicates firefighting efforts. Due to dangers posed by steel rack shelving, firefighters have not entered the building. Ventilation typically needed to clear smoke is hampered by the insulated roof.

According to Los Angeles Fire Department Chief Jaime Moore, the warehouse contains massive rows filled with frozen food pallets similar to those in large retail stores like Costco. An estimated 85 million pounds of frozen goods, including seafood, pork, beef, and poultry, are stored inside.

“I don’t foresee ever putting our firefighters in that type of danger,” said Moore, given the compromised roof sitting atop 65-foot towers.

Firefighters are removing exterior walls and using heavy water streams to manage the blaze.

Fire Origin

The fire reportedly began while subcontractors were working on solar panels on the roof. Lineage Logistics, the Michigan-based company operating the facility, believes this may have been the cause, although the official reason has not been confirmed. Lineage is cooperating with authorities investigating the fire.

Air Quality Concerns

The South Coast Air Quality Management District has issued warnings on air quality, extending through Tuesday. Smoke contains microscopic PM2.5 particles, affecting Boyle Heights and areas northeast. Light winds could spread smoke across greater Los Angeles.

Residents are advised against vigorous activities, keeping homes sealed, and moving pets indoors. Those venturing outside should wear protective masks like N95 or P100, as recommended by health officials.

Community Impact

Los Angeles City Councilmember Ysabel Jurado, representing Boyle Heights, emphasized the need for transparency about the materials burnt and the ongoing fire effects. Results should be communicated to residents in an accessible language.

The local community has reported smoke visibility, odors, and ash near residences and businesses.
