Los Angeles Cold Storage Warehouse Fire Enters Sixth Day as Smoke Blankets Southern California

A massive fire at a frozen-food storage warehouse near downtown Los Angeles has persisted for six days, with firefighters still unable to enter the 500,000-square-foot facility operated by Michigan-based company Lineage. The fire, which began on June 19 when subcontractors were working on solar panels on the roof, has created significant challenges for emergency responders due to the building's heavily insulated structure, thick walls, and ceiling, which trap heat and smoke and prevent rapid ventilation.

The warehouse, known as Big Bear, contained approximately 85 million pounds of frozen food stored in rows 65 feet tall and 650 feet long, loaded on heavy-duty steel rack shelving. According to Los Angeles Fire Department Chief Jaime Moore, firefighters have not been able to safely enter the building because the compromised roof is sitting atop these towering racks, creating an extremely dangerous environment. Instead, firefighters have been stripping away exterior walls on certain sides of the building and using heavy water streams in an attempt to extinguish the blaze from outside. Officials acknowledged that while typical warehouse fires can be extinguished within a day, cold storage facility fires commonly burn for weeks due to their specialized construction.

The persistent smoke has created significant air quality concerns across Southern California. The South Coast Air Quality Management District extended warnings about poor air quality, noting that the smoke carries microscopic PM2.5 particles that can penetrate deep into the lungs. The warehouse is located across the street from homes in Boyle Heights, a working-class neighborhood east of downtown Los Angeles. City officials warned residents to stay indoors, keep windows and doors closed, and wear N95 or P100 masks if going outside. Light winds were expected to push smoke throughout the metropolitan Los Angeles area.

The facility stores products including seafood, pork, beef, and poultry destined for grocery stores and restaurants on the U.S. West Coast. While Lineage stated that it believes subcontractors working on solar panel installation sparked the fire, the official cause has not yet been determined as investigations continue. Local officials, including Los Angeles City Councilmember Ysabel Jurado representing Boyle Heights, have called for transparency regarding what materials and chemicals were stored in the warehouse and what remains burning.
