July 29, 2019 Wildfire Regulation
Posted on: 19th September, 2019
A new Cal/OSHA emergency regulation, effective July 29, 2019, requires that when the Air Quality Index* is 151 or higher due to wildfire smoke, employers must:
- Allow workers to work indoors in effectively filtered buildings when feasible, or
- Relocate workers to areas with better air quality, or
- Provide outdoor workers with approved respirators, such as N95 respirators.
Employers must also check air quality at outdoor work sites at the start of each shift when they anticipate workers may be exposed to smoke.
The resources listed below offer details on the new regulation as well as information that can be used for worker trainings on the harmful effects of wildfire smoke and safe and effective use of respirators.
*This refers to the Air Quality Index (AQI) for particulate matter 2.5 micrometers and smaller (PM2.5).
