Staying Safe from Wildfire Smoke
To protect yourself from wildfire smoke, it is recommended to stay informed about air quality conditions, use high-efficiency air filters, and consider portable HEPA air purifiers. Limit outdoor activities, keep windows and doors closed, and avoid using wood-burning appliances during smoky conditions. Respirator masks like N-95 or P-100 can offer some protection for outdoor exposure.
Safely Cleaning After a Wildfire
When cleaning ash post-wildfire, wear protective gear like goggles, gloves, and a respirator mask. Wash ash off pets and belongings, mist floors with water before sweeping, and dispose of collected ash properly. Avoid using leaf blowers and prevent ash-water mixtures from entering storm drains. Use a vacuum with disposable filter bags for indoor cleaning.
