A fire at a cold storage warehouse burned for eight days in June. The facility used thousands of pounds of anhydrous ammonia, a toxic refrigerant, to cool the warehouse. Anhydrous ammonia can cause respiratory irritation and, in large doses, lead to lung and eye damage or death.

Real-time logs reportedly contradict initial statements from the warehouse's owner and the Los Angeles Fire Department chief, who said there was no ammonia leak. The fire has raised health concerns that have persisted for weeks.

Further details about the incident are available, including information about a previous ammonia release at a related facility in North Carolina.
