For confidence and peace of mind

COVID-19 is an emerging viral infectious disease.

With so much information and misinformation out there, we thought we would put together some solid data on the disinfectants that have been approved for use against COVID-19. The following information is current as of 20 MAY 2020.

Claims that a disinfectant has an effect against any virus must be expressly permitted by the Australian Government, Department of Health, Therapeutic Goods Administration (TGA) before being used in consumer advertising (including on the label).

Safe Work Australia explains that disinfecting means using chemicals to kill germs on surfaces. It is important to clean (different topic) before disinfecting because organic matter and dirt can reduce the ability of disinfectants to kill germs. Safe Work Australia recommends the following:

Hard surfaces

Disinfectants containing ≥ 70% alcohol, quaternary ammonium compounds, chlorine bleach or oxygen bleach are suitable for use on hard surfaces (that is, surfaces where any spilt liquid pools, and does not soak in). These will be labelled as ‘disinfectant’ on the packaging.

 

Soft or porous surfaces

Disinfectant is not suitable on fabric surfaces as it only works with extended contact time with the surface.
Talking about different surface types, according to the Harvard Medical School, Coronavirus resource centre; A recent study found that the COVID-19 coronavirus can survive up to four hours on copper, up to 24 hours on cardboard, and up to two to three days on plastic and stainless steel.

The Australian Commission on Safety and Quality in Health Care Guidelines on the prevention and control of infection states that during a norovirus outbreak, routine cleaning should be intensified with the use of a detergent solution followed by the use of a Therapeutic Goods Administration-listed hospital-grade disinfectant with specific claims so that surfaces are cleaned and disinfected.

When using sodium hypochlorite (i.e. bleach) as a disinfectant in addition to standard cleaning practice to manage norovirus outbreaks, a minimum dilution factor of 1:10 should be used, equivalent to 0.1% active chlorine.

When using sodium hypochlorite to disinfect hard surfaces, the following should be considered:

    • environmental surfaces should be clean and free of matter
    • allow sufficient time to kill the virus – at least 10 minutes of surface contact time
    • dilution of sodium hypochlorite (10% bleach solution) should be made up fresh, just before use (1:10 solution = 1 part bleach for every 9 parts water).

This concentration and advice are aligned with the advice provided in the Infection control guidelines for the public health management of gastroenteritis outbreaks due to norovirus or suspected viral agents in Australia.

 

Benefits and harms

Whilst the benefits of sodium hypochlorite use outweighs the harms, there are potential adverse effects involved in using such products. However, these can be minimised by safe handling in accordance with the Safety Data Sheets.

 

Certainty of the Evidence

The evidence for this practice statement is limited or inconsistent. This practice statement is based on the advice of experts and trends in clinical practice.

 

Resources and other considerations

Sodium hypochlorite is inexpensive and its feasibility has been demonstrated by widespread existing use.

 

Rationale

This advice is based on limited empirical evidence, but on sound theoretical principles and supported by expert advice. The use of sodium hypochlorite to manage norovirus-specific outbreaks is justified to reduce healthcare associated infection.

 

This is a solution with 0.5% chlorine concentration
1:10 bleach solution

Add 1 part of your bleach product to 9 parts water to create a disinfectant solution that can be used safely.

  1. Bleach solutions for disinfection must be freshly prepared and cannot be stored for later use.
  2. Bleach solutions may irritate the skin, corrode metal and bleach fabric. Always use gloves and eye protection when creating a bleach solution and take care not to spill bleach.
  3. Ensure you are in a well-ventilated area when creating a bleach solution.
  4. Always rinse objects and surfaces with water after disinfection to ensure that all sodium hypochlorite has been removed
