Overview
- The fire began on Wednesday, June 17, on the roof of a roughly 500,000-square-foot Lineage-operated cold-storage warehouse and has burned for days because interior access is unsafe.
- Firefighters have shifted to defensive, exterior tactics and have removed sections of the outer wall while using helicopters and high-volume water streams to reach and douse hidden hot spots.
- Air monitors recorded PM2.5 in levels from unhealthy for sensitive groups to very unhealthy, prompting particle-pollution advisories, distribution of masks and purifiers, school relocations and local respite centers.
- Lineage says the blaze likely started during rooftop solar work, confirmed that ammonia was pumped offsite with no measurable community concentrations, and has donated $2 million plus purifiers and supplies to affected residents.
- Cold-storage fires burn long because thick insulation, tall racking and large frozen inventories trap heat and smoke, which raises cleanup, food-disposal and long-term air and soil monitoring questions for the neighborhood.
