Regulation to Protect Workers from Wildfire Smoke Goes into Effect in California
A new emergency regulation to protect outdoor workers in California from wildfire smoke is now in effect. According to Cal/OSHA’s press release (PDF), the emergency regulation is effective through Jan. 28, 2020, with two possible 90-day extensions. The regulation applies to workplaces where the current Air Quality Index for airborne particulate matter, or PM 2.5, is 151 or greater and where employers should “reasonably anticipate that employees could be exposed to wildfire smoke.”
The new regulation requires employers to identify harmful exposure to airborne particulate matter from wildfire smoke at the start of each shift and periodically thereafter by checking the AQI for PM 2.5 in regions where workers are located. Employers must reduce harmful exposure to wildfire smoke by relocating work to an enclosed building with filtered air or to another outdoor location where the AQI for PM 2.5 is 150 or lower. If employers cannot reduce workers’ exposure to wildfire smoke so that the AQI for PM 2.5 is 150 or lower, they must provide respirators to all employees for voluntary use. Employers must also provide training on the new emergency regulation, the health effects of wildfire smoke, and the safe use and maintenance of respirators.
