Disinfectant and Anti Viral Cleaning Services
Cleaning and Disinfection
Buildings and people
• Accommodation facilities may include supported residential services, high rise towers, boarding houses, boarding schools and hotels.
• Building occupier means the organisation that is responsible for the facility and the occupants within it.
• Visitors may include students, children, residents, clients, patients and 3rd party providers.
• Frequently touched surfaces mean a surface that is touched often by multiple hands and at risk of being contaminated and of spreading germs.
• High touch surfaces (also called high touch points) is the term used in this guideline to mean frequently touched surfaces.
• Minimally touched surface means a surface that is touched less often for example, glass windows, ceilings, curtains or floors.
• Cleaning means physically removing germs, dirt and organic matter from surfaces. Cleaning alone does not kill germs, but by reducing the numbers of germs on surfaces, cleaning helps to reduce the risk of spreading infection.
• Damp dusting means the use of a slightly dampened cloth, achieved by spraying with water or a cleaning agent, or wetting then wringing out to prevent drips, then wiping surfaces with the damp cloth.
• Deep cleaning means thorough cleaning and disinfection of high touch surfaces and objects in a workplace area that a suspected or confirmed coronavirus (COVID-19) case was identified to have been during their infectious period.
• Disinfection means using chemicals or thermal (moist or dry heat) to kill germs on surfaces. Cleaning before disinfection is very important as organic matter and dirt can reduce the ability of disinfectants to kill germs.
• Fogging means using systems that can apply a disinfectant under high pressure, with a droplet size less than 10 microns (dry fogging), or between 20 to 100 microns (wet, cold or Ultra Low Volume fogging or misting). The department does not recommend the use of dry or wet fogging disinfection for COVID-deep cleans.
• Detergent means a surfactant that is designed to break up oil and grease with the use of water.
• Disinfectant solution is a product that is a Therapeutic Goods Administration-listed household/commercial grade disinfectant, labelled with the specific claim to kill viruses or Australian Register of Therapeutic Goods listed as effective against coronavirus (COVID-19). A disinfectant product may be applied as a liquid, spray or impregnated wipe.
• Surfactant is a surface-active agent, which means a substance that when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties.
Cleaning of visibly dirty surfaces followed by disinfection is a best practice measure for prevention of COVID-19 and other viral respiratory illnesses in community settings.
It is unknown how long the air inside a room occupied by someone with confirmed COVID-19 remains potentially infectious. Facilities will need to consider factors such as the size of the room and the ventilation system design (including flowrate [air changes per hour] and location of supply and exhaust vents) when deciding how long to close off rooms or areas used by ill persons before beginning disinfection. Taking measures to improve ventilation in an area or room where someone was ill or suspected to be ill with COVID-19 will help shorten the time it takes respiratory droplets to be removed from the air.
