A Guide to Breathing Safely During Wildfires

Wildfire season can bring hazy skies and a distinct smell of smoke, posing a significant health risk even for those far from the flames. The fine particles in smoke and ash can travel deep into your lungs and cause a range of health problems. This guide will help you understand how to protect yourself and your family with simple, effective measures.

Common Mistakes to Avoid

When air quality drops, it's easy to make well-intentioned mistakes. Here are two common pitfalls to avoid.

Mistake 1: Believing any face covering is enough.
Many people grab a simple cloth mask or bandana, thinking it's better than nothing. However, wildfire smoke contains microscopic particles (called PM2.5) that can easily pass through these materials. They don't provide a seal around your face, allowing polluted air to leak in.

Mistake 2: Using a leaf blower for ash cleanup.
It seems like a fast way to clear ash from your driveway or patio, but using a leaf blower is a major hazard. It sends the fine, potentially toxic ash particles airborne again, where they can be easily inhaled by you or your neighbors.

Why Proper Protection Matters

The difference between correct and incorrect methods directly impacts your respiratory health. Inhaling fine particles can cause immediate issues like coughing, stinging eyes, and a scratchy throat. For individuals with asthma, heart disease, or other respiratory conditions, it can trigger severe health events.

By using the right mask and cleaning techniques, you prevent these harmful particles from entering your body. Keeping your indoor air clean creates a safe refuge, reducing your overall exposure and protecting your long-term health. Failing to do so means you continue to breathe in pollutants, even when you think you are being safe.

Simple Steps to Protect Your Lungs

Getting started with wildfire smoke safety is straightforward. Focus on these key actions:

Monitor Air Quality: Stay informed about your local Air Quality Index (AQI). Websites like AirNow.gov provide real-time data. When the AQI is high, limit your time outdoors.
Create a Clean Air Space: Keep doors and windows closed. If you have an HVAC system, use a high-efficiency filter and set it to recirculate. A portable air purifier with a HEPA filter is also highly effective for a single room.
Use the Right Mask: If you must go outside, wear a NIOSH-approved respirator, such as an N95 or P100 mask. It must fit snugly over your nose and mouth with two straps that go around your head to create a proper seal.
Clean Up Safely: After the smoke has cleared, wear a mask, gloves, and goggles to clean up ash. Lightly mist surfaces with water to prevent dust from kicking up, then use a broom or mop. For indoor cleaning, use a vacuum equipped with a HEPA filter.
