Wildfire Smoke Safety: A Step-by-Step Guide

Wildfires pose significant health risks due to the smoke they produce, which can travel vast distances and degrade air quality. Understanding how to protect yourself before, during, and after a wildfire is crucial.

Before a Wildfire

1. Stay Informed

  • Monitor Air Quality: Regularly check your community's air quality using the Air Quality Index (AQI) at AirNow.gov. (cdc.gov)

  • Follow Local Alerts: Pay attention to local weather forecasts and heed instructions from local emergency management officials. (cdc.gov)

2. Prepare Your Home

  • Seal Off Rooms: Designate a room that can be closed off from outside air to serve as a cleaner air space. (cdc.gov)

  • Enhance Indoor Air Quality: Use high-efficiency filters (preferably MERV 13 or higher) in your central air conditioning system. (cdc.gov)

  • Avoid Indoor Pollutants: Refrain from burning candles, incense, or using gas stoves during smoky conditions. (cdc.gov)

3. Assemble Emergency Supplies

  • Stock Up on Essentials: Ensure you have a 7-10 day supply of prescription medications and non-perishable foods. (cdc.gov)

  • Prepare Respirators: Obtain NIOSH-approved N95 respirators to reduce smoke inhalation if you need to go outside. (cdc.gov)

During a Wildfire

1. Limit Outdoor Activities

  • Stay Indoors: Remain inside as much as possible to minimize exposure to smoke. (cdc.gov)

  • Use Respirators When Necessary: If you must go outside, wear a well-fitting N95 respirator to filter out smoke particles. (cdc.gov)

2. Protect Vulnerable Individuals

  • Special Precautions: Children, pregnant women, and individuals with chronic conditions like asthma or heart disease should take extra care during smoky conditions. (cdc.gov)

3. Stay Updated

  • Monitor Air Quality: Continue to check air quality reports and follow local advisories. (cdc.gov)

After a Wildfire

1. Assess Air Quality

  • Check Conditions: Even after the fire is out, smoke can linger. Use AirNow.gov to monitor air quality. (cdc.gov)

2. Clean Up Safely

  • Protect Yourself: When cleaning up ash, wear gloves, long-sleeved clothing, and a NIOSH-approved N95 respirator. (cdc.gov)

  • Avoid Using Water from Private Wells: Wildfire ash can contaminate water sources; do not use private well water until it's deemed safe. (cdc.gov)

3. Seek Medical Attention if Needed

  • Monitor Health Symptoms: If you experience persistent coughing, difficulty breathing, or other health issues, consult a healthcare professional. (cdc.gov)

By following these steps, you can significantly reduce the health risks associated with wildfire smoke. Always prioritize safety and stay informed through reliable sources.
