Cal/OSHA Protection from Wildfire Smoke training video
CaliforniaDIR
Overview
This video explains the Cal/OSHA regulation designed to protect workers from the health hazards of wildfire smoke. It details the primary pollutant, PM2.5, its health effects, and the Air Quality Index (AQI) trigger for protection. The training outlines employer responsibilities, including monitoring AQI, implementing control measures like moving work indoors or providing filtered air, and offering NIOSH-certified respirators when necessary. It also covers proper respirator use, limitations, and worker rights regarding reporting symptoms and seeking medical attention.

Chapters
- Wildfire smoke poses a significant risk to workers in California.
- The primary harmful component in wildfire smoke is fine particulate matter known as PM2.5.
- PM2.5 particles are extremely small (2.5 micrometers or less) and can penetrate deep into the lungs and bloodstream.
- Exposure to PM2.5 can cause respiratory irritation, reduced lung function, and exacerbate conditions like asthma and heart problems.
Understanding the nature of wildfire smoke and its primary pollutant, PM2.5, is crucial for recognizing the risks and the necessity of protective measures.
PM2.5 particles are about 30 times smaller than the average human hair, illustrating their ability to easily enter the body.
- Cal/OSHA has a specific regulation (Title 8, Section 5141.1) to protect workers from wildfire smoke.
- The regulation applies when employers can reasonably anticipate smoke exposure and the Air Quality Index (AQI) for PM2.5 reaches 151 or higher.
- The AQI is a measure of air pollution, with 151 indicating unhealthy air for everyone.
- Workers in filtered, mechanically ventilated structures or vehicles are generally exempt if doors are kept closed.
Knowing the specific regulation and the AQI threshold (151) is essential for both employers and employees to determine when protective actions must be taken.
An AQI of 151 or higher means the air quality is considered 'unhealthy for everyone,' triggering employer obligations under the regulation.
- Employers must monitor the current AQI for PM2.5 at or near the workplace.
- Information on AQI can be found on government websites like AirNow.gov, or obtained through employer communication.
- Employers are required to inform employees about the current AQI at the start of each shift and periodically thereafter.
- If the AQI is 151 or higher, employers must implement measures to reduce exposure, starting with moving work indoors or to filtered environments.
This section clarifies the active role employers must take in monitoring air quality and communicating risks to their workforce.
Employers can check websites like AirNow.gov or sign up for EnviroFlash to get AQI alerts for specific locations.
- When AQI is 151+, employers must first try to relocate work indoors or into filtered vehicles.
- If relocation isn't possible, other measures include changing work schedules, reducing intensity, or increasing rest breaks.
- If exposure cannot be sufficiently reduced, employers must provide NIOSH-certified respirators (like N95 or P100) for voluntary use when AQI is 151-500.
- When AQI exceeds 500, respirator use becomes mandatory for most workers, with employers providing medical evaluations and fit testing as part of a respiratory protection program.
This outlines the hierarchy of controls, emphasizing that respirators are a last resort after other protective measures have been attempted or proven insufficient.
If moving work indoors isn't feasible, an employer might offer more frequent rest breaks in a clean air area as an interim measure before providing respirators.
- Respirators must be NIOSH-certified filtering facepiece types (e.g., N95, P100) and worn correctly to be effective.
- Proper fit involves a snug seal, with straps positioned correctly and facial hair that could interfere with the seal removed.
- Cloth masks, surgical masks, and bandanas do not provide adequate protection against wildfire smoke.
- Employers must train workers on respirator use, limitations (e.g., not protecting against gases), and proper storage.
- Workers have the right to report worsening air quality or symptoms to their employer without fear of retaliation and to seek medical attention.
Ensuring correct respirator use and understanding worker rights are vital for maximizing protection and maintaining a safe working environment.
To ensure a proper seal, a worker required to wear an N95 respirator must shave any beard or significant stubble that prevents the mask from fitting tightly against their skin.
Key takeaways
- Wildfire smoke's primary danger comes from microscopic PM2.5 particles that can severely impact respiratory and cardiovascular health.
- Cal/OSHA mandates worker protection when the PM2.5 AQI reaches 151 or higher, requiring employers to actively monitor and manage air quality.
- Employers must implement a hierarchy of controls, prioritizing moving work indoors or using filtered air before resorting to respirators.
- NIOSH-certified respirators are effective only when selected, worn, and maintained correctly; they are not a substitute for other control measures.
- Workers must be trained on the risks of wildfire smoke, the use and limitations of protective equipment, and their rights to report issues and seek medical care.
- Simple cloth masks or surgical masks are insufficient protection against wildfire smoke; only NIOSH-certified respirators offer adequate filtration.
