Disinfection practices are important to reduce the potential for COVID-19 virus contamination in non-healthcare settings, such as in the home, offices, schools, gyms, publicly accessible buildings, and faith-based community centers. High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices.
Which surface disinfectants are effective against COVID-19?
In non-health care settings, sodium hypochlorite (bleach / chlorine) may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water). Alcohol at 70-90% can also be used for surface disinfection. Surfaces need to be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection. Cleaning should always start from the least dirty area to the cleanest area in order to not spread the dirty to areas that are less soiled.
What protection measures should people take when using disinfectants?
Avoid combining disinfectants, such as bleach and ammonia, since mixtures can cause respiratory irritation and release potentially fatal gases.
