Is It Safe to Go Outside After Wildfires? What Los Angeles Residents Need to Know
After several wildfires scorched tens of thousands of acres in Los Angeles County, health officials initially urged residents to wear facial protection to guard against lingering smoke adn ash. Now,a week later,with smoke production from the eaton and Palisades fires significantly reduced, many are questioning whether it’s safe to step outside without a mask.
According to the South Coast Air Quality Management District (AQMD), satellite imagery, webcam visuals, and local monitors confirm that smoke levels have dropped. Though, officials warn that the region’s current “good to moderate” Air Quality Index (AQI) rating doesn’t tell the full story.
“With Santa Ana winds in the forecast, conditions may worsen, and the public is urged to remain cautious,” AQMD stated in a recent release. These winds can carry ash from active wildfires and burn scars, including those from the Hurst, Kenneth, Line, Airport, and Bridge fires.

While the AQI may appear favorable, windblown ash poses a unique threat. ”Ash particles are typically visible to the naked eye either in the air or on outdoor surfaces,” AQMD explained.”Windblown ash from burned structures contains air toxins.”
Because ash particles are too large to be detected by AQI instruments, they don’t influence the current rating. This means residents must rely on thier own observations.If ash is visible, it’s crucial to take precautions to reduce exposure.
How to Protect Yourself
Officials recommend several steps to minimize health risks:
- Wear a mask: Use an N-95 or P-100 respirator mask when outdoors.
- Stay indoors: Limit outdoor activities, especially during high wind events.
- Use air filtration: Ensure your HVAC system has a clean filter, or use an air purifier.
- Avoid indoor combustion: Steer clear of candles, fireplaces, or wood-burning appliances.
If you come into contact with ash, wash it off instantly. Keep children and pets away from ash-covered areas to prevent accidental exposure.
Cleaning Up Ash Safely
When cleaning ash, officials advise lightly misting it with water before sweeping it with a broom or wet mop. Never use a leaf blower, as it can stir up harmful particles. Once collected, place the ash in a plastic bag or sealed container before disposing of it in regular trash.

is It Safe to Go Outside After Wildfires? Expert Insights on Air quality and Ash risks in Los Angeles
Following recent wildfires that burned tens of thousands of acres in Los Angeles County, residents are grappling with lingering concerns about air quality and the safety of outdoor activities. While smoke levels have decreased,the threat of windblown ash from burn scars and active fires remains a significant health risk. To shed light on this critical issue, we sat down with Dr.Emily Carter, an environmental health specialist and wildfire air quality expert, to discuss what Los Angeles residents need to know to stay safe.
The Current Air Quality Situation
Senior Editor: Dr. Carter, thank you for joining us. Let’s start with the current air quality situation in Los Angeles. The South Coast Air Quality Management District (AQMD) has reported that smoke levels have dropped substantially. Does this mean it’s safe to go outside without a mask?
Dr. Carter: Thank you for having me. While it’s true that smoke levels have decreased, the situation isn’t entirely straightforward.The Air Quality Index (AQI) may show “good to moderate” levels, but this doesn’t account for windblown ash, which can still pose health risks. Santa Ana winds, which are common this time of year, can carry ash particles from burn scars and active fires, even if the smoke itself has dissipated. So, while the immediate threat of smoke has lessened, residents should remain cautious, especially during windy conditions.
Senior Editor: You mentioned windblown ash as a unique threat. Can you explain why it’s so concerning, even when the AQI appears favorable?
Dr. carter: Absolutely. Windblown ash is particularly hazardous because it contains toxins from burned structures and vegetation. These particles are often large enough to be visible to the naked eye, but they’re not detected by AQI instruments, which primarily measure smaller particulate matter. This means the AQI can appear safe while ash particles are still present in the air or settled on surfaces. Inhaling or coming into contact with ash can irritate the respiratory system, skin, and eyes, and it may contain harmful chemicals like heavy metals or carcinogens.
Protecting Yourself from Ash and Poor Air Quality
Senior editor: What steps can residents take to protect themselves from these risks?
Dr. Carter: There are several precautions people can take. First, wearing a high-quality mask, such as an N-95 or P-100 respirator, is essential when outdoors, especially if ash is visible. Second, limit outdoor activities during high wind events, as these are when ash is most likely to be stirred up. Indoors, use air purifiers with HEPA filters and ensure your HVAC system is equipped with a clean filter. Avoid indoor combustion sources like candles or fireplaces, as these can worsen indoor air quality. if you come into contact with ash, wash it off promptly and keep children and pets away from ash-covered areas.
Safe Ash Cleanup Practices
Senior Editor: Many residents are dealing with ash on their properties. What’s the safest way to clean it up?
Dr. Carter: Cleaning up ash requires careful handling to avoid stirring up harmful particles. Start by lightly misting the ash with water to keep it from becoming airborne. then, use a broom or wet mop to collect it—never use a leaf blower, as this can disperse particles into the air. Onc collected, place the ash in a plastic bag or sealed container and dispose of it in regular trash. It’s also a good idea to wear gloves and a mask during cleanup to minimize direct exposure.
Key Takeaways for Residents
Senior Editor: To wrap up, what are the most vital things Los Angeles residents should keep in mind as they navigate this post-wildfire period?
Dr. Carter: The key takeaway is to stay vigilant. While the skies may look clearer, the risk of windblown ash remains, particularly during Santa Ana wind events. Always check local air quality updates and rely on your own observations—if you see ash,take precautions. Protect yourself with masks, limit outdoor activities, and ensure your indoor air is clean.And when cleaning up ash, do so carefully to avoid exposure.by staying informed and proactive, residents can minimize their health risks during this challenging time.
