Abstract

Non-touch technology using UV vapor or hydrogen peroxide vapor has been been introduced for environmental decontamination in hospitals. Hydrogen peroxide is a hazardous substance; therefore, any exposure should be to concentrations less than 1 ppm according to occupational safety and health standards. The residual concentration of hydrogen peroxide after the dispersal of Nocospray® hydrogen peroxide vapor was measured and adjusted for ventilation time because the air conditioning system in every medical institution is different. It is important to determine a patient’s admission time based on the concentration of hydrogen peroxide remaining in a room to ensure staff and patient safety.
