The Los Angeles Fire Department continued to battle a dayslong blaze at a Lineage Logistics cold storage warehouse on South Los Palos Street in Boyle Heightsas city and state emergency declarations enabled more resources and air quality alerts were extended. Crews reported persistent flare-ups since the fire began Wednesday, with smoke plumes shifting across neighborhoods and new advisories covering portions of central Los Angeles County and the San Gabriel Valley. Last updated: June 21, 2026.
The incident matters because the facility stores an estimated 85 million pounds of frozen foodincluding perishable meat, and its insulated construction has complicated suppression and produced widespread smoke impacts. Health officials kept a particle pollution advisory in effect through Sunday, cautioning sensitive groups about PM2.5 exposure while noting that detected spikes of bromine and chlorine remained below short-term health thresholds. Local leaders opened relief centers and urged residents near the site to limit outdoor activity and use masks when possible.
Firefighting tactics and evolving conditions in Boyle Heights
Officials said the fire originated in a rooftop solar systemthen spread within the building’s foam-insulated cavities and behind corrugated steel, creating zero-visibility conditions inside and defying conventional interior attacks. LAFD Chief Jaime Moore described the response as “very unique,” deploying a structural firefighting robot and heavy-lift helicopters capable of dropping up to 3,000 gallons per pass—an approach usually reserved for brush fires. Crews also continued exterior operations to cool the roof and prevent further collapse risks while systematically assessing hotspots.
On Friday afternoon, a large plume of white smoke rose from the structure, signaling a flare-up as winds shifted. LAFD Chief Nick Ferrari told residents this was anticipated and that the incident would remain “an extended event” while teams cut access paths and drowned concealed fire. A spokesperson said smoke color varied—white indicating water hitting hot materials, brown pointing to active material combustion—while crews adapted tactics to changing wind and heat conditions around South Los Palos Street and nearby blocks.
Air quality advisories and public health measures
The regional air district extended its Particle Pollution Advisory through 1:30 p.m. Sunday, citing periods of unhealthy to very unhealthy PM2.5 in central Los Angeles County, the San Gabriel Valley, and adjacent areas. Early monitoring found particles largely at background levels with brief increases in bromine and chlorine; officials said measured values stayed below short-term health-based thresholds and no significant air toxic metals were detected. Forecasts warned that wind could push smoke toward Southeast Los Angeles County on Sunday, prompting continued messaging for sensitive groups to remain indoors.
City departments opened smoke and fire relief centers at Pecan Park Recreation Center (145 S. Pecan St.) and City Terrace Park (1126 N. Hazard Ave.), with N95 masks and air filtration support available on a limited basis through the council office in Boyle Heights. Community organizations, including Proyecto Pastoral Running Mamis and Centro CSOdistributed masks and checked on vulnerable residents. Mayor Karen Bass urged people to stay indoors when possible and to mask up outside, while some neighbors, like Gabriela Dueñas, voiced frustration about the pace of official updates and asked for more frequent messaging via city channels.
Emergency declarations and community response
The city declared a local emergency and the state issued a state of emergency to mobilize specialized resources, accelerate logistics, and pre-position supplies. Governor Gavin Newsom said the state was supporting local firefighters and moving critical assets to protect communities and speed recovery. The declarations unlocked additional tools for the ongoing operation, including sustained aerial water drops, specialized equipment, and support for public health measures in affected neighborhoods.
Inside the warehouse, firefighters coordinated to safely remove perishable food where accessible to prevent secondary hazards while continuing to monitor structural stability. Councilmember Ysabel Jurado said the city needed decisive action and called for equitable fire service across neighborhoods. LAFD spokesperson Lyndsey Lantz reiterated that crews were prepared for wind shifts and foam-insulation challenges, noting the shift between white and brown smoke as a real-time indicator of suppression progress. With flare-ups still possible, officials maintained round-the-clock monitoring and advised residents to track city alerts for evolving conditions.
