Uncovering the Health Risks of L.A.-Area Fire Smoke and Ash: County Issues Warning
As Santa Ana wind conditions continue to stoke fears of resurgent wildfires across Los Angeles County, health officials are warning of yet another wind-borne threat: ash and dust from active fire zones and burn scars.
County Department of Public Health Advisory:
On Tuesday, the county Department of Public Health issued a windblown dust and ash advisory until 7 p.m. Wednesday. Ash may be dispersed from the Palisades and Eaton fire areas, as well as from the Hurst, Kenneth, Line, Airport, and Bridge fire burn scars, according to the South Coast Air Quality Management District. The advisory stated that while ash particles may be too large to be detected by air quality instrumentation and will not influence Air Quality Index levels, they are typically visible to the naked eye either in the air or on outdoor surfaces.
Expert Insights:
Wildfire smoke is unsafe for everyone. Anne Kelsey Lamb, director of Regional Asthma Management and Prevention at the Public Health Institute, highlighted the dangers of particulate matter in smoke, which can cause respiratory issues and other health problems. At-risk individuals, such as children, pregnant women, older adults, and those with respiratory or heart conditions, are especially vulnerable to the harmful effects of wildfire smoke. Lamb emphasized the importance of taking precautions to protect against the potential health risks associated with exposure to wildfire smoke.
The Concerns:
Researchers have found that wildfire smoke, containing fine particulate matter known as PM2.5, can lead to premature deaths. The toxic materials present in wildfire smoke, such as lead, asbestos, and arsenic, pose additional health risks to individuals exposed to the smoke. In addition to PM2.5, the smoke from Los Angeles-area fires can contain harmful components from burned structures and materials, making it particularly concerning for public health.
Expert Recommendations:
Experts recommend staying indoors with windows and doors closed to minimize exposure to wildfire smoke. Protective gear such as N95 masks, air purifiers, and gloves can help individuals reduce their risk of inhaling harmful pollutants. People with beards are advised to shave or trim facial hair to ensure a tight seal with protective masks. Additionally, changing clothes and washing them immediately after outdoor exposure can prevent the spread of particulate matter inside the home.
Protecting Pets:
Pets are also at risk from wildfire smoke, especially those with cardiovascular or respiratory conditions. Keeping pets indoors, limiting outdoor exposure, and avoiding intense exercise during poor air quality periods can help protect animals from the harmful effects of smoke.
Monitoring Air Quality:
Even though some harmful particles may not be detected by air quality monitoring instruments, individuals are encouraged to monitor air quality in their area using tools such as AirNow and Purple Air. These resources provide real-time data on particulate matter levels and air quality index readings to help people make informed decisions about their outdoor activities.
Obtaining N95 Masks:
Free N95 masks are available at various locations in Los Angeles County, including L.A. Care Health community resource centers, Los Angeles Public Library branches, and city recreation and senior centers. These masks can help individuals protect themselves from the harmful effects of wildfire smoke.
Conclusion:
As wildfires continue to pose threats to public health, it is essential for individuals to take proactive measures to safeguard their well-being. By following expert recommendations, monitoring air quality, and utilizing protective gear, people can minimize their exposure to harmful pollutants and reduce the risks associated with wildfire smoke and ash. Stay informed, stay safe, and take care of yourself and your loved ones during these challenging times.
