“During a wildfire, smoke can make the outdoor air unhealthy to breathe. Local officials may advise you to stay indoors during a smoke event. You should be aware that some of the smoke from outdoors can enter your home and make it unhealthy to breathe indoor air, too.” – EPA
“Wildfire smoke and cleanup presents hazards that employers and workers in affected regions must understand. Smoke from wildfires contains chemicals, gases and fine particles that can harm health. Hazards continue even after fires have been extinguished and cleanup work begins. Proper protective equipment and training is required for worker safety in wildfire regions.” – Cal/OSHA
