A. General Good Practices
1. As the virus can survive on surfaces of different materials for at least 2-3 days, surfaces potentially contaminated with COVID-19 virus should be sanitized.
2. Even after persons have been isolated in other facilities, do not host visitors in the residence until the place is sanitized.
3. Seek medical attention if you are feeling unwell.
4. Avoid sharing household items (e.g. dishes, drinking glasses, cups, eating utensils, bedding). After using the items, wash them thoroughly with soap and water.
B. Cleaning of Residences
I. Items to Prepare for Home Cleaning
Prepare these items before you start to clean your home:
1. Personal protective equipment (PPE)
Residences of confirmed COVID-19 cases
Change of clothes
2. An appropriate disinfectant with indication of effectiveness against coronavirus, or bleach solution. Please refer to the “Interim List of Household Products and Active Ingredients of Disinfection of COVID-19 ” for a list of disinfectants and active ingredients that are suitable for coronavirus disinfection. Note that different active ingredients require different periods of contact time between the disinfectant and the surfaces to be effective.
3. A change of clothes
4. Plastic/Trash bags
6. Disposable cloths or rags
II. Cleaning Instructions
1. Where possible, leave the rooms used by the confirmed case undisturbed for at least 3 hours before cleaning. The room(s) should not be occupied until cleaning and disinfection is carried out. If there is a need to enter the room before it is cleaned or disinfected, put on appropriate PPE (Section B.I.1) before entering.
2. Before you start cleaning, put on a surgical mask and a pair of gloves. Avoid toucing your face and eyes during clean-up.
3. Prepare the disinfectant according to the manufacturers’ recommendations or bleach solution (for bleach, dilute to 1000ppm or 0.1% sodium hypochlorite; bleach solutions with 5.25-6.00% sodium hypochlorite can be diluted using 1 part bleach in 49 parts water). Alcohol can be used for surfaces where the use of bleach is not suitable.
4. Keep the windows open for ventilation.
5. Mop the floor with the prepared disinfectant or bleach solution, starting from one end of the home to another.
6. Soak cloths with the prepared disinfectant or bleach solution and use them to wipe all frequently touched areas (e.g. handles, doorknobs, armrests, seatbacks, tables, keyboards, mouse, switches, blinds, windows, walls, etc.) and toilet surfaces.
7. Avoid using a spray pack to apply disinfectant as it may create splashes which can further spread the virus. Also, alcohol-based disinfectant is flammable, do not spray it into the air.
8. Clean toilets with separate set of cleaning equipment (disposable cleaning cloths, mops, etc) using disinfectant or bleach solution. Use an appropriate disinfectant and note that different active ingredients require different periods of contact time to be effective.
a. Cleaning all accessible surfaces (sinks, taps, soap dispensers, toilet roll dispensers, walls, doors, locks, handles, flush buttons, etc).
b. Clean urinals and toilet bowls with a brush and use a separate cloth for seat covers. Brush and cloths used for these should not be used for other surfaces.
c. After disinfection, clean the floor with disinfectant from the exit inwards.
9. Remove bed sheets, pillows covers, blankets, curtains and other fabrics for washing. Avoid tossing or throwing the laundry. Use a washing machine and detergent to wash preferably using the hot water cycle. For hot-water laundry cycles, wash with detergent or disinfectant in water at 70oC for at least 25 minutes. If low-temperature (i.e. less than 70oC) laundry cycles are used. choose a chemical that is suitable for low-temperature washing when used at the proper concentration.
10. If person(s) are still being tested for COVID-19, do not use personal belongings/used items such as mattresses, pillows, carpets or cushions until they are determined to be free of infection. Contact NEA at 1800-2255-632 for further instructions if the person(s) are confirmed to have COVID-19.
11. Repeat cleaning the floor with the prepared disinfectant or bleach solution, starting from one end of the residence to another. Avoid going from an area that has not been cleaned to an area that has been cleaned, to avoid dirtying the cleaned area.
12. Throw away all cloths and rags used, as well as other waste from the clean-up, into double-lined plastic/trash bags.
13. Disinfect buckets by soaking in disinfectant or bleach solution.
