Update at 7:00 PM on 6/23/26:

Operations continue today at the Palos Fire in Boyle Heights as firefighters remain engaged in complex suppression efforts within the damaged building. Smoke conditions have improved significantly, and the surrounding community should notice better air quality as firefighting operations continue.

The building's layout, combined with large amounts of foam insulation and structural damage, continues to create unique challenges and limits firefighters' ability to safely work inside the structure. Crews are working alongside local, state, and out-of-state partners, using specialized heavy equipment and high-capacity water streams from the exterior to safely access and extinguish remaining hot spots.

Cold storage facilities like this have historically been among the most challenging fires to fight. While crews continue to make steady progress, the safety of all personnel remains the top priority. Although significant progress has been made, crews expect operations to continue as they safely extinguish remaining pockets of fire within the structure.

We appreciate the continued patience and support of the Boyle Heights community as operations remain active.

The LAFD has received multiple inquiries on air quality resulting from the smoke. During the ongoing firefighting efforts, we are seeing smoke impacts throughout the region. Those areas change based on wind and weather and the amount of smoke generated from the incident. A smoke advisory is currently in effect and South Coast AQMD will continue to monitor the smoke plume, weather and air quality conditions and will extend their advisory as needed.

South Coast AQMD has been monitoring the air quality since early in the incident. South Coast AQMD monitors are collecting particulate matter (PM2.5 & PM10), ozone (smog), carbon monoxide, and nitrogen dioxide.

Mobile monitoring for Ammonia, Hydrogen Fluoride, and toxic metals (e.g., lead, chromium, arsenic, etc.) was performed on Wednesday and Thursday multiple times near the structure and in the adjacent neighborhood and no significant levels were observed.

South Coast AQMD has deployed additional Particulate matter (PM2.5) monitors at Eastman Avenue Elementary and Robert Louis Stevenson Middle School and is feeding that data into their air quality map to provide near real-time localized information. This is in addition to our ongoing air monitoring data from our regionally placed air monitors and hundreds of local sensors.

South Coast AQMD is providing technical oversight of additional community monitoring, being conducted by a private contractor. (Onterris)

The EPA is supporting the Los Angeles Fire Department, the lead for this incident, in performing ongoing air monitoring and sampling. EPA continues to work in close coordination with state and local partners throughout the response.

The EPA and LA County Health HazMat are currently on scene monitoring the perimeter of the building fire for air toxics.

The data and air quality map can be found at https://www.aqmd.gov.

Residents are encouraged to use the Air Quality map to help make decisions about the type of precautions they should take. Air Quality may change quickly based on conditions. You may smell smoke even if the AQI does not show elevated PM2.5 levels yet. Given the elevated levels of PM2.5 and significant smoke impacts, if you smell smoke, please take precautions. Run an air purifier or air conditioning with a high efficiency filter if available; avoid using a whole house fan or swamp cooler as they can bring polluted air indoors. If you see or smell smoke, we advise residents to remain indoors with doors and windows closed. Consider wearing a well-fitting N95 mask. Note, this is not a shelter in place order. If you have to be outside, minimize heavy activity.

Information on the AQI scale and what associated health effects might be of concern to diverse individuals within a population, and recommend precautions at each level can be found at: https://www.aqmd.gov/home/air-quality

Update at 7:00 PM on 6/21/26:

LAFD firefighters continue to make significant progress at the Palos Incident through coordinated suppression operations and heavy equipment support.

Crews have removed sections of the exterior wall allowing for more effective access to interior fire areas, giving them the ability to apply large volumes of water.

The building's construction continues to present operational challenges. Interior storage rack systems remain in place and are supporting portions of the collapsed roof, creating complex and unstable conditions that require a cautious and methodical approach. Firefighters are operating with a strong emphasis on safety and are closely monitoring potential structural failure hazards.

Fire conditions along the exterior portions of the structure have been largely knocked down. The next phase of operations will focus on accessing and extinguishing remaining fire within more interior areas of the building.

Smoke conditions have improved significantly and are expected to continue improving as firefighters make progress extinguishing the fire. Although smoke conditions are trending in a positive direction, intermittent increases in smoke may occur as crews open walls and other concealed spaces to locate and extinguish hidden fire.

Updated at 10:30 AM on 6/21/26:

Throughout the evening and into the morning hours, LAFD firefighters have continued to work tirelessly to gain control of the Palos Incident. Crews have successfully confined the fire to one side of the large building. Overnight, firefighters removed portions of the exterior wall to improve access and allow for more effective water application to areas of the fire that were otherwise inaccessible.

The building presents significant safety and operational challenges, including large storage racks that limit firefighters' ability to safely deploy handlines inside the structure. Many of the solar panels have been de-energized, and multiple lithium-ion batteries have been removed from the building, significantly reducing hazards to both firefighters and the surrounding community.

LAFD personnel will continue firefighting operations throughout the day, applying large volumes of water to extinguish remaining fire. As a result, the volume and color of smoke visible to the community may fluctuate.

Update at 8:00 PM on 6/20/26:

Aerial suppression operations have concluded for the evening. Ground crews will remain actively engaged throughout the night, utilizing a large amount of water and the LAFD structural firefighting robot.

Firefighter safety remains the top priority, as crews have identified areas of wall instability due to the significant volume of water being applied to the structure. Smoke conditions are expected to continue evolving as weather conditions change and suppression efforts progress. This remains a complex, long-duration incident that will require sustained operations.

---

Update at 2:39 PM on 6/18/2026: LAFD will soon be undertaking ventilation measures to evacuate hazardous smoke from 1400 S Los Palos St. Residents in Genasys zone 1279 EAST OF LORENA ST are ordered to SHELTER IN PLACE. Residents in Genasys zones 1281, 1239, 1241, and 1279 WEST OF LORENA are advised that they may see smoke in the area.

BOYLE HEIGHTS - On June 17, 2026, Los Angeles Fire Department crews responded to a fire at a large single-story commercial building at 1400 S Los Palos Street, following an alarm at 2:35 PM.

Upon arrival, firefighters found fire visible from the roof of the 1,000' x 500' structure. Crews initially engaged in offensive suppression; however, approximately 15 minutes into the operation, a suspected ammonia leak prompted Incident Command to order a defensive posture. LAFD personnel worked to locate and mitigate the source while suppression continued.

As a precaution, the fire building and adjacent businesses were evacuated in the early stages of the incident. A shelter-in-place order was issued for the immediate area, with advisories extended to surrounding areas to the north and east. Incident Command has since lifted all orders and advisories, and residents and employees may safely return. No further evacuations or shelter-in-place orders are anticipated. Air and water quality monitoring will continue during all further operations on scene.

The sheer size of this structure (identified as a cold-storage facility) largely prevented effective ground access, necessitating an unconventional approach. Though not typically deployed in structure fires due to safety concerns, LAFD helicopters performed water drops to knock down the bulk of the flames.

While the fire was largely under control within six hours, extended suppression and overhaul operations are expected. LAFD fire companies, hazmat specialists, drone pilots, and USAR teams are coordinating scene management with partner agencies including LAPD, CHP, LADOT, LADWP, LADBS, the local gas company, and Los Angeles County Health Hazmat.
