Is the Air Safe to Breathe in Boyle Heights During the Warehouse Fire?
If you live or work in or near Boyle Heights during the Lineage warehouse fire, the most useful thing you can do is check real, current air-quality data for your exact location rather than rely on how the air looks or smells.
Check your air quality first
- EPA AirNow (airnow.gov) gives a real-time air quality reading by ZIP code.
- The South Coast AQMD (aqmd.gov) posts particle- pollution advisories specific to Southern California communities; the current advisory has covered central LA County, the San Gabriel Valley, the East San Fernando Valley, and the Northwest San Bernardino Valley.
- The City of Los Angeles Emergency Management page posts incident-specific guidance — those instructions take precedence over anything general.
What officials have said
- The acute chemical risk is contained — Lineage pumped ammonia from the facility's tanks and transported it offsite, and LAFD/AQMD reported no measurable ammonia concentrations in the surrounding community.
- PM2.5 reached unhealthy levels in parts of central LA after the Friday- night reignition; smoke is expected to continue for days while crews finish the knockdown.
Symptoms worth watching for
Smoke and PM2.5 exposure can cause watering eyes, scratchy throat, coughing, and headache. People with asthma, COPD, heart conditions, young children, older adults, and pregnant people may be more sensitive. Seek medical attention for trouble breathing, chest pain, persistent coughing, or any symptom that worsens — and tell the clinician about the incident so it's recorded.
What to do now
- Limit outdoor activity while advisories are in effect.
- Keep windows and doors closed and run AC on recirculate.
- Wear an N95 if you must be outside in smoke; masks and air purifiers are available at Council District 14's Boyle Heights office.
- If you were affected, consider documenting your exposure while details are fresh. To see whether your area is among those being tracked, use the area-lookup tool.

Common questions
How do I check the air quality at my address?
Enter your ZIP at EPA's AirNow (airnow.gov) for the real-time reading, and check the South Coast AQMD for any active advisory. During this incident, AQMD has posted particle-pollution advisories spanning much of central LA County and beyond.
Was there an ammonia leak, and is it still a concern?
Yes, initially. Lineage pumped ammonia from the facility's tanks and transported it offsite, and LAFD/AQMD reported no measurable ammonia concentrations in the community. Smoke and PM2.5 are now the practical issue.
What should I do if the air looks or smells bad indoors?
Close windows and doors, run AC on recirculate if available, and use an air purifier with a HEPA filter if you have one. N95 masks and air-filtration support are available at Council District 14's Boyle Heights office.
