Thick black smoke filled the air as firefighters tackled a blazing warehouse in Boyle Heights, Los Angeles, on Wednesday. This situation has caused significant air quality issues, impacting residents even miles away. Here’s crucial information to help you stay safe.
Air Quality Advisories and Measures
The South Coast Air Quality Management District extended a Particle Pollution Advisory until Sunday at 12:30 p.m. Officials warned that a change in wind direction on Sunday morning might direct smoke toward Southeast LA County. If the fire keeps emitting substantial smoke by Sunday afternoon, Central and East Los Angeles might also be affected.
Precautions for Residents
Authorities advise those with lung conditions or sensitivity to smoke to avoid outdoor activities. They have managed some hazardous materials on-site but express concern over biohazards from spoiled food stored there. This 500,000-square-foot warehouse holds 85 million pounds of frozen goods.
L.A. County Health Officer Muntu Davis highlighted smoke and fine particles as the main risks, irritating the respiratory system and worsening heart and lung conditions. Sensitive individuals should wear well-fitted N95 and P100 masks and sign up for alerts at alertla.org. Will Barrett from the American Lung Association stresses avoiding exposure as smoke content may include harmful chemicals and particles.
Health and Safety Tips
- If smoke or ash is visible, refrain from strenuous outdoor activities and stay indoors with windows and doors shut.
- Utilize an air purifier if available. Avoid whole-house fans or swamp coolers that draw in outside air.
- In case of high indoor temperatures, visit public places like libraries or malls to stay cool.
- Avoid using fireplaces, candles, or vacuums. Clean dust with a damp cloth and avoid smoking indoors.
- If symptoms like severe cough, breathing difficulties, chest pain, or fatigue occur, consult a doctor or visit urgent care. For life-threatening issues, call 911.
Expert Insights
UC Irvine toxicologist Michael Kleinman noted that the spread of smoke depends on wind speed and direction. Experiencing irritation such as eye watering or nose irritation signals a serious concern. The decomposition of massive amounts of spoiled food presents a biohazard. If food begins to burn, it could introduce harmful biological materials into the smoke.
Available Resources
The city set up a smoke respite shelter at Pecan Recreation Center on 145 S. Pecan St., while another is available at City Terrace Park on 1126 N. Hazard Ave. The state will provide technical experts, distribute 5.5 million respirator masks, commercial-grade air purifiers, bottled water, and enhanced air-quality monitors.
