The Los Angeles Fire Department said a structure fire was reported Wednesday afternoon at 1400 S. Los Palos Street in Boyle Heights. In later updates, LAFD described a significant smoke impact, a shelter-in-place order for part of the area, and then, on Wednesday night, the lifting of that shelter-in-place order. The department’s final update still advised people with sensitive health issues to monitor air quality, remain cautious, stay indoors, and keep doors and windows closed to limit exposure to outdoor air.
MyNewsLA reported Thursday that LAFD remained on scene at the cold-storage facility and that the fire had involved a warehouse where smoke and an ammonia leak prompted protective orders. The same report said the shelter-in-place order had been lifted while air quality continued to be monitored.

Why this matters for LA outdoor plans
Los Angeles hikers often make decisions based on heat, wind and parking, but smoke is just as important. Even if a fire is miles from your planned route, wind direction and terrain can move smoke into parks, canyons and ridgelines. Griffith Park, Elysian Park, Debs Park, the Los Angeles River paths, and front-range routes around the Santa Monica Mountains can all feel different from one neighborhood to the next when smoke or haze is present.
If you smell smoke, see visible haze, or have asthma, heart disease, a respiratory condition, or are hiking with children or older adults, the conservative choice is to shorten the outing, choose a lower-effort walk, or postpone until conditions improve. A trail does not need to be officially closed to be a poor choice for someone sensitive to smoke.
Practical checks before heading out
- Check a live air-quality map before leaving, especially if your route is near central Los Angeles, the Eastside, or downwind of Boyle Heights.
- Look for current LAFD or county updates if you plan to be near the incident area.
- Avoid hard uphill efforts if the air smells smoky or chemical, even if the sky looks clear.
- Carry extra water and keep the plan flexible; turn around if breathing feels unusual.
- For pets, remember that dogs can be affected by smoke too, especially on hot pavement or during sustained uphill walks.
For most mountain and coastal hikes, the decision should be local and real-time: check conditions at the trailhead, not only at home. The key confirmed point is that officials lifted the shelter-in-place order, but did not frame that as an all-clear for sensitive people to ignore air quality.
