Air quality Los Angeles: Harmful particle pollution from windblown fire ash
LOS ANGELES - The South Coast Air Quality Management District, in conjunction with the National Weather Service, has issued an air quality alert due to harmful levels of windblown dust and ash as multiple fires continue to burn in the region. Residents in affected areas are advised to take precautions to protect their health, especially vulnerable populations.
What We Know
The South Coast AQMD has issued an air quality alert due to harmful particle pollution levels from windblown dust and ash. This alert affects the South Coast Air Basin and Coachella Valley, with windblown ash possible in areas southwest of recently burned zones. Pollution levels can vary based on emissions and local weather conditions. The alert is in effect from Monday evening until Wednesday at 7 PM.
Impacts
Particle pollution can penetrate deep into the lungs, leading to serious health issues such as asthma attacks, heart and lung disease symptoms, and an increased risk of respiratory infections. While everyone can be affected, sensitive groups—including individuals with lung or heart disease, older adults, pregnant people, children, and those who spend significant time outdoors—are at greater risk.
Precautionary/Preparedness Actions
To protect your health in areas affected by windblown dust and ash, it is advised to:
- Avoid outdoor activities.
- Keep windows and doors closed.
- Use air conditioning and/or an air purifier.
- Avoid using whole-house fans or swamp coolers that bring in outside air if other cooling methods are available.
- Steer clear of other pollution sources such as fireplaces, candles, incense, grilling, and gasoline-powered lawn and garden equipment.
What You Can Do
Residents are encouraged to wear appropriate respiratory protection, such as N95 and P100 masks, which are available for free at L.A. County libraries and Local Assistance Disaster Resource Centers. These masks should be worn correctly, covering the nose and mouth without gaps, and replaced regularly if they become wet or soiled. Cloth masks, dust masks, and bandanas are not considered adequate protection.
Why You Should Care
Protecting vulnerable populations, including those with preexisting conditions, children, and older adults, is crucial during this air quality alert. Consulting healthcare providers before using respirators is recommended for individuals with respiratory conditions. Taking these precautions is essential to mitigate the health risks associated with poor air quality.
