The virucidal efficacy was assessed according to the French regulation AFNOR NF T 72-110: 2019 (Method of disinfection of surfaces by steam with or without contact – Determination of bactericidal, fungicidal, levurocidal, sporicidal and virucidal activity).
On the basis of the results obtained, in the experimental condition adopted, the product under examination causes a reduction greater than or equal to 4.39 Log (99.99%) against Bovine Coronavirus* (BCoV) RVB-0020 with 1 application of continuous steam with a pass at a speed of 10 cm/sec and at a distance of 5 mm from the surface.
Considering that:

It can be said that the steam treatment of Polti equipment must be considered effective in completely deactivating the SARS-CoV2 virus at a temperature of 80°C or higher. With the very high temperatures reached by Polti Sani System, deactivation is effective in very short exposure times (a few seconds).

According to the guidelines of the NF T72-110: 2019-03 standard, in the applied test conditions, the product in question “SDD” has a virucidal effect against Bovine Coronavirus* since the viral reduction of the tested strain is > 4 Log.

*Bovine coronavirus is used as a surrogate virus for SARS-related viruses (including SARS CoV-2) as it belongs to the same genre as Betacoronavirus 1, with a similar morphology and size, but at a Bio Safety Level 2.

The bactericidal, sporicidal, fungicidal, levurocidal efficacy was assessed according to the French regulation AFNOR NF T 72-110: 2019 (Method of disinfection of surfaces by steam with or without contact – Determination of bactericidal, fungicidal, levurocidal, sporicidal and virucidal activity).
The test product used in the experimental condition adopted causes reduction greater than or equal to:

With 1 application of continuous steam with a pass at a speed of 10 cm/sec and at a distance of 5 mm from the surface.

Virucidal efficacy was assessed according to European standard EN 14476 (quantitative test in suspension for the evaluation of virucidal activity in the medical area).
Based on the results obtained, in the experimental condition adopted, the product under examination causes a reduction greater than or equal to 4 Log (99.99%) against Human Influenza A (H1N1) after 15 seconds.

Sanitisation has proved effective for the disinfection of a work surface previously contaminated with the following microorganisms: Escherichia coli, Staphylococcus coagulase negative, Klebsiella pneumoniae and Proteus mirabilis. After the treatment, no bacterial growth was found on the surfaces.

The evidence shows that the product concerned kills 100% of the eggs and 90% of the adult bed bugs at the first pass. In the field tests it completely eliminated the Cimex infestation with between two and three treatments, also successfully degrading the sticky substance that binds the eggs to the surfaces, reducing the smell of bedbugs and eliminating the traces of excrement thanks to the combined use of steam and HPMED.

The bactericidal activity on two strains of Methicillin Resistant Staphylococcus Aureus (MRSA) was analysed on different surfaces.
Use for 30 seconds proved effective for the sanitisation of various materials, including stainless steel and melamine
coatings, with a reduction in the bacterial load of 4 logarithms, while as regards ceramics, a bacte-rial residue was found only for the most resistant MRSA strain (3 logarithms).
This type of test demonstrates a reduction in the bacterial load of 4 log and therefore a reduction of up to
99.99%.

The product concerned showed activity on several Gram positive and Gram negative bacteria and on different types of fungi. Antimicrobial activity has been found on inert equipment, environments and materials such as plastic, metal and glass. Preliminary tests carried out on inert materials demonstrated a significant reduction of up to 99.999% of the tested species.
Under standard operating conditions, the sanitisation carried out caused a reduction in the total microbial load of 91.6%, compared with 88.8% with the traditional method of sanitisation (using chemical products).

30 seconds of treatment with superheated dry steam and HPMed proved effective in reducing the microbial load by 99.999% for Gram positive, Gram negative, filamentous fungi and yeasts. 30 seconds of treatment reduced the spores by 97%.

Experimentation in a real context shows that this is a valid method for sanitising ambulances because it drastically reduces the total microbial load present on surfaces.
