With the Southern California wildfires still raging, Cal/OSHA issued an advisory providing updated guidance to employers with outdoor workers who may be exposed to wildfire smoke.
The advisory states: When outdoor workers are exposed to air quality that is designated “Unhealthy”, “Very Unhealthy” or “Hazardous” by local air quality management districts, employers are required to provide filtering respirators such as masks labeled N95 and certified by the National Institute for Occupational Safety and Health (NIOSH).
