A fire broke out at a large cold-storage warehouse in Boyle Heights, Los Angeles, and authorities told residents nearby to stay inside with windows and doors closed because of a chemical leak, according to Patch.

Warehouses that store frozen food use a gas called ammonia to keep things cold. When a fire breaks the pipes and containers holding ammonia, the gas escapes into the air. This leaking gas can be more dangerous to people than the fire itself because it spreads quickly and can hurt lungs and eyes. The neighborhood around the warehouse has lots of homes and small businesses, so more people are at risk.

Firefighters from the Los Angeles Fire Department arrived and put out the fire. According to the LAFD, they managed to save the building from burning down completely. As of June 17, 2026, officials had not yet confirmed exactly how the fire started, how much damage was done, or which chemical actually leaked.

When officials cannot quickly get a dangerous chemical under control in the air, they tell people to stay indoors — this is called a shelter-in-place order. It keeps residents safe by keeping them away from the gas. How long this order lasts and how big an area it covers depends on air quality tests and wind direction, which authorities were still measuring when the fire was first reported.

This warehouse is run by a company called Lineage Logistics, which owns the world's biggest network of cold-storage facilities. These warehouses store frozen food, medicine, and other temperature-sensitive products that get shipped around the world. When a major warehouse closes, even for a short time, lots of food can spoil and businesses that rely on that warehouse can run short on supplies. How important this particular warehouse is to the area's food supply chain had not been explained in early reports.

This is the second big warehouse fire in Los Angeles in recent years. These incidents might push the city to look more closely at safety rules for warehouses that have solar panels on their roofs. Solar panels create extra complications for firefighters because they can be electrified, which means crews cannot pour water on those roof areas or cut holes to let smoke out — making it harder to fight the fire safely.

As cleanup and investigation begin, officials will provide updates on whether the air is safe again and when the warehouse can reopen.
