5. CLEANING PROTOCOL
- Assign “cleaning crew” or “cleaning task force” to each shift of project
- Provide hourly routine environmental cleaning within jobsite offices/trailers
- Wipe down doorknobs, keyboards, counters, and other surfaces
- If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
- For disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective.
- Diluted household bleach solutions can be used if appropriate for the surface. Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.
- Prepare a bleach solution by mixing: 5 tablespoons (1/3rd cup) bleach per gallon of water or 4 teaspoons bleach per quart of water.
- Products with EPA-approved emerging viral pathogens (external link) are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time, etc.).
- For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove
visible contamination if present and clean with appropriate cleaners indicated for use on these surfaces.
- If the items can be laundered, launder items in accordance with the manufacturer’s instructions using the warmest appropriate water setting for the items and then dry items completely.
- Otherwise, use products with the EPA-approved emerging viral pathogens claims (examples at this link) that are suitable for porous surfaces.
- Cleaning staff should wear disposable gloves and gowns for all tasks in the cleaning process, including handling trash.
- Gloves and gowns should be compatible with the disinfectant products being used.
- Additional PPE might be required based on the cleaning/disinfectant products being used and whether there is a risk of splash.
- Gloves and gowns should be removed carefully to avoid contamination of the wearer and the surrounding area. Be sure to clean hands after removing gloves. Gloves should be removed after cleaning a room or area occupied by ill persons. Clean hands immediately after gloves are removed.
- Cleaning staff should immediately report breaches in PPE (e.g., tear in gloves) or any potential exposures to their supervisor.
- Sanitize reusable PPE per manufacturer’s recommendation prior to each use
- Disinfect reusable supplies and equipment.
- Request additional/increased sanitation (disinfecting) of portable toilets
- Avoid cleaning techniques, such as using pressurized air or water sprays that may result in the generation of bioaerosols.
6. LEAVING THE JOBSITE
- Utilize shoe sanitation tubs (non-bleach sanitizer solution) prior to leaving the jobsite.
- Workers should change work clothes prior to arriving at home – All clothing should not be shook out, keep clothing separated from other laundry, wash with sanitizing detergent and warm water immediately.
