Firefighters continued efforts to extinguish a cold-storage warehouse fire in Boyle Heights on Sunday, entering its fifth day amid growing concerns over deteriorating air quality in the surrounding area.

Los Angeles Fire Department Chief Jaime Moore reported notable progress in managing the blaze, expressing optimism that containment could be achieved by the end of the week if current efforts remain effective. Despite these developments, the fire remained active, producing significant smoke that has affected air quality across large portions of Los Angeles County and neighboring regions.

The South Coast Air Quality Management District (SCAQMD) maintained a particle pollution advisory through 12:30 p.m. Monday, warning residents of hazardous conditions resulting from the persistent smoke. Monitoring stations recorded air pollution levels ranging from “unhealthy for sensitive groups” to “very unhealthy” throughout Los Angeles County, the San Gabriel Valley, and the northwest San Bernardino Valley since Saturday night.

Residents have voiced concerns about the smoke’s impact on health and visibility, with complaints spreading on social media platforms. The smoke was visibly dense enough to shroud Dodger Stadium before Sunday afternoon’s baseball game, underscoring the fire’s extensive reach.

Fire crews continue to focus on containing hotspots within the warehouse, but the incident remains complex due to the building’s structure and contents. Authorities have advised the public to monitor air quality notices and take precautions as necessary.

The ongoing smoke plume and its effects have raised public health concerns amidst the prolonged firefighting operations. Officials have indicated that while progress is steady, the situation requires continued vigilance to ensure both the fire is fully controlled and community health risks are minimized.
