The Boyle Heights community is grappling with a massive warehouse fire that has prompted a state of emergency declaration. The blaze, which ignited on Wednesday at a Lineage Logistics cold storage facility, has posed significant challenges to firefighters and raised concerns about air quality across Los Angeles.

The fire, which originated from a rooftop solar system, has been particularly difficult to extinguish due to the facility’s unique construction and the presence of 85 million pounds of frozen foodincluding perishable meat. The Los Angeles Fire Department (LAFD)led by Fire Chief Jaime Moorehas employed unprecedented tactics, including the use of heavy-lift helicopters capable of dropping up to 3,000 gallons of water at a time.

The Unprecedented Firefighting Effort

The LAFD has described the fire as “very unique,” with firefighters facing zero visibility inside the building due to dense smoke and foam insulation. The facility’s corrugated steel walls have made it challenging to access the fire’s core. To combat the flames, the department has deployed a structural firefighting robot and continued aerial water drops, a tactic more commonly used for brush fires.

“These are unprecedented tactics that are being used,” said Chief Moore, who has been with the department for 31 years. The last time aerial water drops were used for a structure fire in Los Angeles was about six years ago in Echo Park.

Despite the aggressive efforts, flare-ups have continued, with smoke visible across northeast Los Angeles and concerns that a change in wind direction could push smoke towards Southeast Los Angeles County on Sunday.

Air Quality Concerns and Public Health Advisories

The South Coast Air Quality Management District (AQMD) has issued a Particle Pollution Advisory until 1:30 p.m. Sunday, with PM2.5 levels reaching unhealthy and very unhealthy levels for sensitive groups in central Los Angeles County, the San Gabriel Valley, and other nearby regions.

Early monitoring showed particles generally present at background levels, with brief spikes of bromine and chlorine. However, AQMD assured that these levels were below short-term health-based exposure thresholds and not expected to cause adverse health effects. No significant levels of air toxic metals were detected.

City officials have advised residents sensitive to smoke to stay indoors and have set up two fire relief centers in East Los Angeles: the Pecan Park Recreation Center at 145 S. Pecan St. and City Terrace Park at 1126 N. Hazard Ave. N95 masks and air filtration support are available on a first-come, first-served basis at Council District 14’s Boyle Heights office.

State of Emergency and Ongoing Efforts

In response to the fire, Los Angeles Mayor Karen Bass declared a local emergency, and Governor Gavin Newsom declared a state of emergency, enabling the mobilization of additional resources. “California is deploying specialized resources, supporting local firefighters, and pre-positioning critical supplies to protect communities and accelerate recovery,” Newsom stated on social media.

The LAFD continues to douse the roof of the building and monitor the structure for further instability. Firefighters are also working to safely remove the perishable food from the facility. The ongoing efforts highlight the complexity of the situation and the commitment to protecting the community and the environment.
