I am sure you have seen the trend towards fogging disinfection for SARS-CoV-2 (the virus that causes Covid-19). There are a lot of untested processes being used to perform this,which are often performed incorrectly and in some cases causing more risks throughout the process. It is not enough to simply enter a facility that has had a confirmed case of Covid-19,fog a disinfectant onto surfaces, and leave. In order for disinfectant chemicals to work they require:
- surfaces to be cleaned to remove oil, grease and organic material; and
- the disinfectant to stay in contact with the surface for the specified dwell time.
After considerable research into these types of systems, we have ordered the only system that we are aware is TGA approved, the NocoSpay Nocolyse system. Given that Nocolyse isdesigned to be delivered as part of a system in the NocoSpray and NocoMax units, the TGAstates that in the interim to having it's own testing criteria, the French Standard NFT72 281 should be used. NocoMax and Nocolyse are manufactured in France in compliance withNFT72 281 and therefore is approved for use as an Automated Aibourne Disinfection System. The Mocolyse system has been used in Austrlian hospitals, aged care homes andother healthcare related organisations for more than 10 years.
The *Mitchell study, conducted in the Launceston General Hospital found that using theNocoSpray system led to a decrease in residual MRSA contamination in patient roomscompared with their terminal clean process.
Collings have purchased the third NocoMax unit in Australia. We have purchased this largerunit due to the large area that it can disinfect for Covid-19 up to 1,300 square meter area(given a 2.4m ceiling height). This means that we can use this unit in large areas suchas airports, schools and colleges, office buildings etc. With this system, all surfaces still needto be initially cleaned. The advantages of this system are:
the disinfection stage of the decontamination clean is completed with a largereduction in labour;
by automating the process we take out the human error factor of missing somesurfaces or areas; and
as shown by the *Mitchell study, disinfection rates appear to be higher than traditionalterminal cleaning processes.
This is an expensive purchase for Collings, however we want to ensure that we do our part inprotecting Tasmanians once our borders re-open.
