Training Requirements

Cal/OSHA’s regulation §5141.1 “Protection from Wildfire Smoke” requires employers who reasonably anticipate that employees may be exposed to wildfire smoke to provide training to workers in a language and manner they understand, including but not limited to the following topics:

  • What is the air quality index (AQI) and PM2.5
  • The health effects of wildfire smoke exposure and unhealthy AQI levels
  • How to use NIOSH-approved respirators
  • Workplace protections and best practices

What is included in the wildfire smoke safety training and resources provided by WCAHS?

WCAHS provides safety resources on wildfire smoke exposure for both employers and employees. A worksite checklist outlining the action items from the regulation is available in English and Spanish. A double-sided poster and accompanying discussion guide are available in English and Spanish and are useful tools for tailgate trainings and safety reminders in the workplace.

WCAHS offers trainings for agricultural employers and employees that provide a more comprehensive and in-depth review of the health effects of wildfire smoke exposure, worker protection procedures, and more. Trainings typically last about an hour and are offered 3–4 times a year in English or Spanish, online or in person.
