OUTSIDE IN FULL
Full facepiece respirators provide at leastįive times as much protection from fine particles as half facepiece respirators such as filtering facepiece respirators (dust masks). *To filter out fine particles, respirators must be labeled N-95, N-99, N-100, R-95, P-95, P-99, or P-100, and must be labeledĪs approved by the US National Institute for Occupational Safety and Health (NIOSH). "Using Disposable Respirators" (in English and Spanish).
Information on providing respirators to employees. See the following webpages and the "Resources" section below for further Provide proper respiratory protection equipment, such as disposable filtering facepiece respirators (dust masks), other halfįacepiece respirators, or full facepiece respirators*.Examples include changing the location where employees work Implement changes to work procedures or schedules when practicable. Whenever engineering controls are not feasible or do not reduce employee exposures to PM2.5 to less than a current AQI of 151,.Examples include providing enclosed structures or vehicles for employees to work in where the air is filtered. Implement engineering controls, when feasible, to reduce employee exposure to PM2.5 to less than a current AQI of 151 (or to the extent feasible if less than a current AQI of 151 cannot be achieved).Training employees according to section 5141.1 Appendix B.Implement a system for communicating wildfire smoke hazards in a language and manner readily understandable by all employees, including provisions designed to encourage employees to inform the employer of wildfire smoke hazards without fear of reprisal.With certain exceptions, employers must take the following measures to protect workers when the current AQI is 151 or greater: Protect Workers if the Outside Air is Harmful The employer also has the option of measuring current PM2.5 levels with a direct reading instrument, provided it is done soĪccording to the requirements in section 5141.1, Appendix A.The local air quality management district.The local air pollution control district.The Interagency Wildland Fire Air Quality Response Program.Checking AQI forecasts and current AQI for PM2.5 at the following websites or using another effective method (telephone, email, text, etc.) from the agencies listed below:.This can be accomplished by any of the following methods: With exceptions, Section 5141.1 requires employers to determine employee exposure to PM2.5 for worksites covered by this section, at the start of each shiftĪnd periodically thereafter as needed. Reference section 5141.1 for details on the scope and Reasonably anticipate that employees may be exposed to wildfire smoke. Where the current Air Quality Index (AQI) for PM2.5 particulate is 151 or greater ("unhealthy") and where the employer should With exceptions, section 5141.1, Protection from Wildfire Smoke, applies to workplaces and operations In air with an aerodynamic diameter of 2.5 micrometers or smaller). The smallest and usually the most harmful particulate matter is called PM2.5 (solid particles and liquid droplets suspended The greatest hazard comes fromīreathing fine particles in the air, which can reduce lung function, worsen asthma and other existing heart and lung conditions,Īnd cause coughing, wheezing and difficulty breathing. Smoke from wildfires contains chemicals, gases and fine particles that can harm health. It does not discuss additional respiratory hazards forįirefighters and others who work in close proximity to active wildfires.
Who work in locations where wildfire smoke can travel.
