In an effort to protect outdoor workers from hazards associated with wildfire smoke, the Cal/OSHA Standards Board recently approved an emergency regulation establishing new protection requirements(Cal/OSHA Title 8 Section 5141.1.) The standard is applicable when the Air Quality Index for fine particulate matter (PM2.5) is 151 or greater. It applies to employees who work outside or in non-filtered buildings and/or vehicles for more than one hour per shift. Use the Decision-Making Matrix on the left to help guide in the event of a wildfire.
The University of California has measures in place to inform you of, and protect you from, the dangers of inhaling wildfire smoke. To complete Wildfire Smoke Training:
