Abstract
The effectiveness of prophylactic aerosol disinfection with neutral anolyte studied in the infectious zones of the laboratory premises, which works with opportunistic microorganisms and pathogenic biological agents. Electrochemically activated chlorinecontaining disinfectant “Anolyte neutral” with pH 7.2, redox potential + 880 mV and active chlorine content 200 mg/dm3 is highly effective when wiping surfaces in rooms with high microbial contamination and in aerosol volumetric and directed air disinfection. Minimal damage is caused to the processed objects. Aerosol volumetric disinfection of air with a «dry» fog using a cold fog generator leads to a significant decrease in microorganisms in the air by 91.1–94.7 % and is not inferior to ultraviolet radiation in terms of disinfection efficiency (90.7–91.1 %). During aerosol volumetric air treatment, harmful effects on personnel are prevented, objects in the room are not damaged, and bactericidal ultraviolet lamps are not needed. Aerosol directed disinfection of surfaces with a “moistened” fog using a cold fog generator completely destroys microorganisms on smooth accessible surfaces and is not inferior to wiping in terms of disinfection efficiency. Aerosol directed disinfection of hardtoget rough surfaces with a “moist” fog leads to a decrease in bacterial contamination by 97.9–98.9 % and even exceeds the efficiency of wiping (95.8–96.1 %).With aerosol directed treatment, hardtoget surfaces are effectively disinfected, disinfectant consumption is reduced, labor costs for cleaning and additional equipment are reduced by 3–4 times, there is no need to use ladders for processing of lamps, ceilings, ventilation grilles and moving equipment for processing hardtoget places.For daily and general cleaning in healthcare organizations, aerosol volumetric air treatment and aerosol directed surface treatment with neutral anolyte can be recommended.
