Can cleaning processes based on ozone be used for high-touch surfaces in nursing homes in areas critical for infection control?

In terms of infection control, environmental cleaning is critical in nursing homes, including long term care facilities. According to the statement of the Commission of Hospital Hygiene and Infection Prevention (KRINKO) at the Robert Koch Institute Berlin on the requirements for disinfectants in these areas, procedures should be used that have been certified by the Association for Applied Hygiene (VAH) for the necessary spectrum of efficacy (or are listed accordingly in the disinfectant list of the Robert Koch Institute). Since ozone is a powerfully oxidizing gas with high inhalation toxicity, the conditions of ap-plication and the measures for occupational safety - including ensuring that the limit value in indoor air is not exceeded when handling and using the product -, must be declared by the manufacturer and observed by the staff to exclude toxic long-term hazard.
