Overview
- The blaze began on June 17 on the rooftop of a 500,000‑square‑foot Lineage‑operated cold‑storage warehouse and crews reported on June 24 that roof flames were out and a knockdown had been achieved.
- Firefighters have not entered the building because thick foam insulation, dense pallet racking and structural hazards keep the fire smoldering inside, so crews are fighting from the outside with long‑reach excavators, peeled exterior walls, water cannons, drone infrared scans and helicopter drops.
- Officials said the site is now in an overhaul phase with teams continuing to douse hotspots and use IR drones to direct high‑volume water while preparing to turn control back to the tenant for cleanup.
- Air monitors from the EPA and AQMD have found no toxins beyond normal structure‑fire products, but particle pollution and smoke forced mask and purifier distributions, temporary school relocations and a rise in respiratory visits to local hospitals.
- Investigations into the origin are ongoing as Lineage has pointed to rooftop solar testing and Altus Power and contractors say the cause remains undetermined, and the site faces a costly recovery that will include removing roughly 85 million pounds of frozen food.
