Respirator Decontamination and Disinfection: <br />Communications: <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 />Signatures: <br />Prepared by: Date: <br />Reviewed by: Date: <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 />Elena Strom 6/8/2022 <br />Shawn Roberts 6/8/2022 <br />The Site Safety Officer will update employees on current AQI for PM2.5 verbally during safety <br />briefings and throughout the day by: <br />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 />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 <br />of iodine [6-8 grams ammonium and/or potassium iodide/100 cubic centimeters (cc) of 45 percent <br />alcohol] 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.
