Overview
- The one‑million‑square‑foot Medline distribution center was destroyed by a fast roof fire that began on Thursday, June 11, and the building has been declared a total loss.
- Heavy equipment crews have been removing exterior walls and moving debris so a reduced team of firefighters can reach and extinguish stubborn hotspots inside the collapsed structure.
- Fire officials say the facility’s sprinkler system was not operating during the blaze and the fire marshal and the ATF are involved, but investigators cannot fully examine the origin or suppression records until the site is safe.
- Charred material fell into nearby Tracy neighborhoods, prompting air‑quality alerts, guidance to avoid touching debris, retention‑pond and runoff testing by Medline and Prologis, and a free debris‑pickup hotline run by Clean Harbors.
- Road closures remain in place, Medline has activated contingency distribution plans, and officials urge children, older adults, and people with lung or heart conditions to limit outdoor exposure as cleanup and a possible multiday to multiweek investigation continue.
