§ 5141.1. Protection from Wildfire Smoke.
Current Air Quality Index (Current AQI). The method used by the U.S. Environmental Protection Agency (U.S. EPA) to report air quality on a real-time basis. Current AQI is also referred to as the “NowCast,” and represents data collected over time periods of varying length in order to reflect present conditions as accurately as possible.
The current AQI is divided into six categories as shown in the table below, adapted from Table 2 of Title 40 Code of Federal Regulations, Part 58, Appendix G.
Air Quality Index (AQI) Categories for PM2.5 | Levels of Health Concern | |
---|---|---|
0 to 50 | Good | |
51 to 100 | Moderate | |
101 to 150 | Unhealthy for Sensitive Groups | |
151 to 200 | Unhealthy | |
201 to 300 | Very Unhealthy | |
301 to 500 | Hazardous |
NIOSH. The National Institute for Occupational Safety and Health of the U.S. Centers for Disease Control and Prevention. NIOSH tests and approves respirators for use in the workplace.
PM2.5. Solid particles and liquid droplets suspended in air, known as particulate matter, with an aerodynamic diameter of 2.5 micrometers or smaller.
Wildfire Smoke. Emissions from fires in “wildlands,” as defined in Title 8, section 3402, or in adjacent developed areas.
(1) Check AQI forecasts and the current AQI for PM2.5 from any of the following websites: U.S. EPA AirNow, the Interagency Wildland Fire Air Quality Response Program, the U.S Forest Service, the California Air Resources Board, the local air pollution control district, or the local air quality management district; or
(2) Obtain AQI forecasts and the current AQI for PM2.5 directly from the U.S. EPA, the Interagency Wildland Fire Air Quality Response Program, the U.S Forest Service, the California Air Resources Board, the local air pollution control district, or the local air quality management district by telephone, email, text, or other effective method; or
Exception:
Subsection (c) does not apply if:
(d) Communication. As required by section 3203, the employer shall establish and implement a system for communicating wildfire smoke hazards in a language and manner readily understandable by employees, including provisions designed to encourage employees to inform the employer of wildfire smoke hazards at the worksite without fear of reprisal. The system shall include effective procedures for:
(1) Engineering Controls. The employer shall reduce employee exposure to PM2.5 to less than a current AQI of 151 by engineering controls whenever feasible, for instance by providing enclosed buildings, structures, or vehicles where the air is filtered. If engineering controls are not sufficient to reduce exposure to PM2.5 to less than a current AQI of 151, then the employer shall reduce employee exposures to the extent feasible.
(2) Administrative Controls. Whenever engineering controls are not feasible or do not reduce employee exposures to PM2.5 to less than a current AQI of 151, the employer shall implement administrative controls, if practicable, such as relocating work to a location where the current AQI for PM2.5 is lower, changing work schedules, reducing work intensity, or providing additional rest periods.
(A) Where the current AQI for PM2.5 is equal to or greater than 151, but does not exceed 500, the employer shall provide a sufficient number of respirators to all employees for voluntary use in accordance with section 5144 and encourage employees to use respirators. Respirators shall be NIOSH-approved devices that effectively protect the wearers from inhalation of PM2.5, such as N95 filtering facepiece respirators. Respirators shall be cleaned or replaced as appropriate, stored, and maintained, so that they do not present a health hazard to users. Employers shall use Appendix B to this section in lieu of Appendix D to section 5144 for training regarding voluntary use of respirators.
Note: For those employees whose only use of respirators involves the voluntary use of filtering facepieces, such as N95 respirators, fit testing and medical evaluations are not required by section 5144.
(B) Where the current AQI for PM2.5 exceeds 500, respirator use is required. Respirators shall be used in accordance with section 5144. The employer shall provide respirators with an assigned protection factor, as listed in section 5144, such that the PM2.5 levels inside the respirator correspond to an AQI less than 151.
