To investigate effective methods to sterilize a biological safety cabinet contaminated with Bacillus spores, a sterilization study was performed using the vaporized KMT reagent. Five kinds of test carriers inoculated with Bacillus subtilis spores, which had been prepared inhouse, were used as indicators. The KMT reagent was placed in the middle of the work-area (1.2 m-wide, Class II type A cabinet). Approximately 300 ml of vaporized KMT reagent could bring about complete sterilization of this cabinet by 24 h of exposure without severe corrosion. Vaporized KMT reagent could be used for the safe and easy sterilization of cabinets contaminated with Bacillus spores.
