Résumé

The cleanliness and microbiological safety of helmets is an important issue for many and frequent users whether they are used in a professional setting and / or for leisure activities. Today, chemicalbased spray disinfectant solutions are or can be used. Although the real effectiveness of these solutions is still to be demonstrated, the persistence of these chemicals compounds after treatment can be a real security problem for exposed users. The CleanCasc © process, developed as part of this study, proposes an alternative method of decontamination and deodorization of helmets using ozone gas. The results obtained during this feasibility study (i.e. commercial apparatus used) and synthesized in the framework of this presentation demonstrate that, depending on the different process parameters (ozone concentration, gas flow rate, etc.), the device used is perfectly capable to induce a reduction of more than 5 log10 (CFU/mL) of a standard strain of Staphylococcus aureus after 3 minutes of ozone gas application. Even though the CleanCasc © (Figure 1) process is being finalized before the start of its large-scale commercialization phase, it can now be seen that the implementation of ozone gas during treatment makes it possible to respond already to requirements in terms of disinfection.
