COVID-19 Interim <br /> Health & Safety Guidance <br /> o If products on EPA List N: Disinfectants for Coronavirus (COVID-19)are not available, bleach solutions can <br /> be used if appropriate for the surface and will be effective against coronaviruses when properly diluted. <br /> ■ Most household bleach contains 5%-9% sodium hypochlorite. Do not use a bleach product if the <br /> percentage is not in this range or is not specified, such as some types of laundry bleach or splash-less <br /> bleach as these are not appropriate for disinfection. <br /> ■ Follow the directions on the bleach bottle for preparing a diluted bleach solution. If your bottle does not <br /> have directions, you can make a bleach solution for disinfecting by mixing: <br /> — 5 tablespoons (1/3 cup) of bleach per gallon of room temperature water; OR <br /> — 4 teaspoons of bleach per quart of room temperature water. <br /> ■ Follow the manufacturer's application instructions for the surface. If instructions are not available, leave <br /> the diluted bleach solution on the surface for at least 1 minute before removing or wiping. This is known <br /> as the "contact time"for disinfection. The surface should remain visibly wet during the contact time. <br /> ■ Ensure proper ventilation during and after application (for example, open windows). <br /> ■ Never mix household bleach (or any disinfectants) with any other cleaners or disinfectants. This can <br /> cause vapors that may be very dangerous to breathe in. <br /> ■ Make a new diluted bleach solution daily. Bleach solutions will not be as effective after being mixed <br /> with water for over 24 hours. Products with EPA-approved emerging viral pathogen claims are expected <br /> to be effective against COVID-19. Follow the manufacturer's instructions for all cleaning and <br /> disinfecting products (e.g., concentration, application method and contact time, etc.). <br /> • Soft(Porous) Surfaces <br /> o For soft (porous) surfaces, remove visible contamination if present and clean with appropriate cleaners <br /> indicated for use on the surfaces. After cleaning: <br /> ■ Launder items as appropriate in accordance with the manufacturer's instructions. If possible, launder <br /> using the warmest appropriate water setting for the item and dry items completely; or <br /> ■ Use products with the EPA-approved emerging viral pathogens that claim they are suitable for porous <br /> surfaces. <br /> • Electronics <br /> o For electronics such as tablets, touch screens, keyboards, remote controls, etc. remove visible <br /> contamination if present. <br /> ■ Follow the manufacturer's instructions for all cleaning and disinfection products. <br /> • Consider use of wipeable covers for electronics. <br /> ■ If no manufacturer guidance is available, consider the use of alcohol-based wipes or sprays containing <br /> at least 70% alcohol to disinfect touch screens. Dry surfaces thoroughly to avoid pooling of liquids. <br /> • Linens, Clothing, and Other Items that Go in the Laundry <br /> o Although it is unlikely field clothing would become potentially contaminated with COVID-19, it is <br /> recommended that field staff regularly launder field clothing following any field event upon returning home. <br /> o In order to minimize the possibility of dispersing the virus from potentially contaminated clothing, do not <br /> shake dirty laundry. <br /> o Wash items as appropriate in accordance with the manufacturer's instructions. If possible, launder items <br /> using the warmest appropriate water setting for the items and dry items completely. <br /> o Clean and disinfect hampers or other containers used for transporting laundry according to guidance listed <br /> above. <br /> 01/2022 COVID-19 Interim Health and Safety Guidance I ROUX 19 <br />
