Voluntary use of other types of respirators meeting NIOSH N-95 protection, such as half-facepiece or <br /> full facepiece air purifying respirators equipped with particulate cartridges, the cartridges will be <br /> changed out using the same criteria above for dust masks or will be changed out in accordance with <br /> manufacturer's end of service life (ESLI) recommendations. <br /> Respirator Decontamination and Disinfection: <br /> Disposable dust masks will not be decontaminated or disinfected and will be disposed after use. For <br /> other types of respirators, the following cleaning and disinfecting procedure will be used: <br /> 1) Remove cartridges/canisters/filters. Disassemble facepiece by removing speaking diaphragm, <br /> demand and pressure-demand valve assemblies, hoses, or any components recommended by the <br /> manufacturer. <br /> 2)Wash components with warm (<110' F)water with a mild detergent or with a cleaner approved by <br /> the manufacturer. A soft, non-wire bristle brush may be used to facilitate dirt removal. <br /> 3) Rinse with warm (<110' F) clean water, preferably running water. <br /> 4) If the cleaner used does not contain a disinfecting agent, respirator components should be <br /> immersed in one of the following for two minutes: <br /> a) Hypochlorite solution (50 ppm chlorine) made by adding approximately 1 milliliter of laundry bleach <br /> to 1 liter of water at 110° F; or <br /> b)Aqueous solution of iodine (50 ppm iodine) made by adding approximately 0.8 milliliters of tincture of <br /> iodine [6-8 grams ammonium and/or potassium iodide/100 cubic centimeters (cc) of 45 percent alcohol] <br /> to one liter of water at 110° F; or <br /> c) Other commercially available cleansers of equivalent disinfectant quality, when used as directed by <br /> the manufacturer, and are approved for use by the respirator manufacturer. <br /> 5) Thoroughly rinse the respirator components in clean, warm, (<110' F) running water. <br /> 6) Components should be hand dried with a soft lint free cloth or allowed to air dry. <br /> 7) Reassemble the facepiece and restore cartridges/canisters/filters as necessary. <br /> 8) Test the respirator for proper working condition. <br /> Communications: <br /> The Site Safety Officer will update employees on current AQI for PM2.5 verbally during safety briefings <br /> and throughout the day by: <br /> Two-way radio communications <br /> X Cell or satellite phone via voice or text <br /> Other method: <br /> Utilization of WorkCare for Smoke Inhalation Questions or Concerns: <br /> Employees experiencing diffculty breathing due to wildfire smoke exposure (regardless of the AQI)or <br /> through voluntary use of a respirator are expected, as a matter of Arcadis policy, to contact WorkCare <br /> (1-888-449-7787)for medical evaluation and guidance. <br /> Signatures: <br /> Prepared by: Elena Strom Date: 7/3/2023 <br /> Reviewed by: Shawn Roberts Date: 7/3/2023 <br />
