CDPH Shares Health and Safety Tips for Those Affected by Wildfires
Multiple wildfires are burning in the Los Angeles area, producing smoke and ash that can pose health risks. Vulnerable groups—such as older adults, children, individuals with respiratory conditions, and pregnant people—are especially at risk. To mitigate health impacts, residents are advised to stay indoors and limit outdoor activities.
The California Department of Public Health (CDPH) is urging Californians affected by wildfire smoke to take immediate steps to protect their health. With multiple wildfires burning across the Los Angeles region, CDPH Director and State Public Health Officer Dr. Tomás Aragón emphasized the importance of reducing exposure to smoke and ash. Residents are encouraged to stay indoors, limit outdoor activities, and monitor the local air quality index (AQI) through EPA AirNow.
“Wildfires, along with the resulting smoke and ash, can have serious health impacts, particularly for vulnerable individuals such as children, older adults, pregnant people, and those with respiratory illnesses,” said Dr. Aragón. “Reducing exposure is critical. Stay indoors when possible and take precautions to protect your health.”
Steps to Reduce Smoke and Ash Inhalation
To minimize health risks, CDPH recommends the following measures:
- Stay Indoors
Indoor environments with filtered air and climate control are safest during smoke episodes. Public spaces with air conditioning can also provide relief. - Adjust Air Conditioning Systems
Set your AC to re-circulate or close outdoor air intakes to prevent smoky air from entering. Replace air filters regularly. - Avoid Indoor Pollutants
Limit activities like smoking, using gas or wood-burning stoves, and burning candles, as these can increase indoor particle levels. - Reduce Physical Activity
Limit exercise or strenuous activities that increase air intake during smoky conditions. - Prepare for Evacuation
Monitor local wildfire activity and be ready to evacuate if instructed by authorities. - Clean Ash Safely
- Avoid sweeping ash dry; use water, a damp cloth, or a mop for cleanup.
- Do not use leaf blowers or other methods that may stir ash into the air.
- Wear Protective Equipment
Use a well-fitting respirator mask (N95 or P100), gloves, long sleeves, and long pants during ash cleanup. Avoid skin contact with ash and wash exposed areas promptly. - Use Proper Vacuums
Avoid standard vacuums that lack HEPA filters, as they can release fine ash particles into the air. - Protect Children and Pets
- Keep children away from ash and clean ash off toys and surfaces before use.
- Wash ash off pets to prevent accidental ingestion or skin irritation.
- Prepare Emergency Supplies
- Keep an emergency kit with essential medications, prescriptions, and supplies ready.
- Locate nearby shelters, including those accommodating pets.
- Seek Medical Attention
If you experience chest pain, tightness, or difficulty breathing, seek medical care immediately.
Health Risks of Wildfire Smoke
Wildfire smoke contains fine particles that can penetrate deep into the lungs, affecting respiratory and cardiovascular health. Symptoms include persistent coughing, wheezing, reduced lung function, and exacerbation of asthma. Prolonged exposure may lead to bronchitis, eye irritation, and other complications.
Individuals with heart or lung conditions should consult their healthcare provider before using respirators, as they can make breathing more difficult.
Evacuation and Emergency Resources
Wildfires may necessitate evacuations. Follow local officials’ instructions and stay informed through:
- Local news outlets
- Emergency responders’ official social media channels
For disaster preparedness, visit ready.ca.gov. Additional resources are available on the CDPH Wildfires page and the California Office of Emergency Services website. Public health officials can access detailed wildfire response guidance in CDPH’s publication, Wildfire Smoke Considerations for California’s Public Health Officials (August 2022).
“Your safety is our priority,” added Dr. Aragón. “If you are ordered to evacuate, do so immediately to protect yourself and your loved ones.”
Stay informed, stay safe, and prioritize your health during this challenging time.
