ABSTRACT

Ozone generator is one of the promising novel disinfectant technology that have recently been proposed as the alternative to conventional decontamination methods such as heat and chemical sanitizers. The objective of this research was to examine various properties of ozone generator to ensure safety and to further proper hygiene practical guideline. The tests are performed by evaluated the propertiesof chemical and microbiological on bacteria that cause clinically important pathogens at different times and cytotoxicity to Cellosaurus cell line OUMS-36 fibroblasts. Moreover, the efficacy of sterilization techniques (soaking, and spraying) of this disinfectants was compared as well. The results showed that ozone-sprayed water, ozone treated water, and ozone treated air has an ability to kill all bacteria within 1-3, 15-20 and 3-5 minutes respectively. Toxicity test and Phenol coefficient of ozone-treated water showed that it is low toxicity level and showed 0.125 times to phenol. Moreover, the use of immersion technique on smooth surface object were found to be more effective for cleaning contaminated than spraying and fabrics, which take only 15-20 minutes to disinfect. In summary, ozone generator is effective in disinfecting surfaces of objects and safe for cleaning surfaces, and other equipment. This research contributes to increasing confidence in safety and as a guideline to carry out for the better and suitable hygiene in the future.
