Boyle Heights Cold Storage Fire: A Warehouse Fire Extinguisher Guide for Los Angeles Businesses
Key takeaways
- A cold storage facility fire in Boyle Heights in June 2026 took LAFD about a week to fully knock down.
- On September 24, 2026, crews spent about 2.5 hours on a commercial building fire on South Santa Fe Avenue in Downtown LA.
- Warehouse fires grow fast. Portable extinguishers are built for the first few minutes, so placement and training matter as much as the equipment.
- A standard 20 lb ABC unit, with a Purple K unit near fuels and a wheeled unit at the docks, covers most LA industrial sites.
What happened at the Boyle Heights cold storage fire?
According to the Los Angeles Fire Department (LAFD Spokesperson Lyndsey Lantz), the alarm came in at 2:35 p.m. on June 17, 2026, for a large single-story cold storage facility at 1400 S. Los Palos Street in Boyle Heights, about 1,000 by 500 feet. Firefighters started with an offensive attack but moved to a defensive posture because of a suspected ammonia leak. LAFD even used helicopter water drops, which is unusual for a structure fire.
Foam insulation and a collapsed roof made the fire hard to reach. LAFD declared knockdown at 5:58 p.m. on June 24, 2026, and a smoke advisory stayed in place while South Coast AQMD and the EPA monitored air quality.
What happened on South Santa Fe Avenue in Downtown LA?
NBC Los Angeles (Danielle Smith, September 24, 2026) reported a fire just after 3:30 p.m. at a one-story, 75-by-50-foot building in the 900 block of South Santa Fe Avenue, a building that had burned before. Firefighters put it out in about two and a half hours, and LAFD, LAPD, LADOT, Building and Safety, LADWP and the gas company all responded. No injuries were reported.
What we don’t know: Both causes were listed as under investigation or not reported, so we make no assumption about how either fire started.
What should LA warehouse operators take from these fires?
Large buildings, insulated panels, stacked pallets, packaging and refrigeration all let a fire grow faster than staff can react. You can’t control how a fully developed fire behaves. You can control how quickly the first person on scene gets the right extinguisher on a small fire, or decides to evacuate. For businesses in Boyle Heights, Vernon, Commerce, the Arts District, Wilmington and the San Fernando Valley industrial corridor, that comes down to four things:
- Right rating: ABC for general storage, Purple K (B:C) for flammable liquids and propane, and Class K in any break-room commercial cooking area.
- Right size: 20 lb units give you more agent and reach than the 5 lb units often left over from office fit-outs.
- Right spacing: Under NFPA 10, no one should travel more than 75 feet to a Class A extinguisher. Add units at every exit, dock door and hazard area.
- Right upkeep: A visual check every month, annual maintenance by an OSFM-licensed concern in California, and hydrostatic testing on schedule.

Frequently asked questions
How many fire extinguishers does a warehouse need in Los Angeles?
It depends on floor area, hazard level and layout. Under NFPA 10, which California adopts through the Fire Code, the maximum travel distance to a Class A extinguisher is 75 feet, with added units near specific hazards. Your fire inspector or a licensed fire protection concern can confirm the count for your building.
What size fire extinguisher is best for a warehouse?
Most warehouses standardize on 20 lb ABC dry chemical extinguishers, such as the Amerex A411 or 423, rated 10A:120B:C. They carry much more agent than 5 lb office units. Wheeled 50 lb or larger units are added for docks and yards.
When should a warehouse use Purple K instead of ABC?
Purple K is a B:C agent built for flammable liquid and gas fires, so it’s common near forklift propane cylinders, fuel storage and solvents. ABC is still the general-purpose choice for ordinary combustibles like pallets and cardboard.
How often must warehouse fire extinguishers be inspected in California?
Staff should visually inspect extinguishers monthly. Annual maintenance, recharging and hydrostatic testing must be done by a concern licensed by the California Office of the State Fire Marshal.
