Wildfire Smoke Alert: Cal/OSHA Urges Employers to Protect Workers from Unhealthy Air in Ventura and Los Angeles Counties

January 23, 2025 | Los Angeles, CA — MedLegalNews.com — Wildfire smoke safety is a growing concern as the Hughes Fire has significantly impacted air quality in Ventura and northern Los Angeles Counties, prompting Cal/OSHA to issue a Wildfire Smoke Alert. This alert emphasizes the urgent need for employers to protect workers from hazardous air conditions caused by wildfire smoke. Areas such as Castaic, Santa Clarita, and Oxnard are currently experiencing unhealthy air, with the potential for further spread. For the latest updates on the fire, road closures, and evacuation orders, refer to the California Department of Forestry and Fire Protection (Cal Fire).

Understanding the Wildfire Smoke Standard

Under Cal/OSHA’s Protection from Wildfire Smoke standard, employers must take specific steps to safeguard workers’ health when wildfire smoke poses risks.

Key Requirements for Employers:

  • Monitor Air Quality: Employers are responsible for tracking the Air Quality Index (AQI) for PM2.5 levels before and during each work shift.
  • Provide Respirators:
    • AQI Above 150: Employers must offer N-95 respirators and encourage their use.
    • AQI Above 500: Respirator use becomes mandatory for all workers.
  • Adjust Work Practices: Employers should modify outdoor work schedules or relocate activities to reduce exposure to hazardous air.
  • Training: Workers must receive training on wildfire smoke hazards and how to use respirators effectively.

Detailed resources and training materials, available in English and Spanish, can be found at WildfireSmokeCalifornia.org and HumodeIncendios.org.

Tracking Air Quality

Monitoring air quality is crucial for ensuring workplace safety during wildfire events. Employers can track AQI levels through U.S. EPA’s AirNow, local air quality management district websites, or on-site instruments that measure PM2.5 levels in compliance with Cal/OSHA standards.

Worker Protections in Evacuation Zones

Cal/OSHA also reminds employers that it is illegal to retaliate against workers who refuse to work in unsafe conditions, including evacuation zones. Workers have the right to prioritize their safety without fear of repercussions. More details can be found in the Worker Safety: Wildfire Smoke and Evacuation Zones Fact Sheet, available in multiple languages.
