| Abstract: | Objective Chlorine dioxide (CD) gas has been used as a fumigant in the disinfection of biosafety laboratories. In this study, some experiments
were conducted to assess the inactivation of spores inoculated on six materials stainless steel (SS), painted steel (PS),
polyvinyl chlorid (PVC), polyurethane (PU), glass (GS), and cotton cloth (CC)] by CD gas. The main aims of the study were
to determine the sporicidal efficacy of CD gas and the effect of prehumidification before decontamination on sporicidal efficacy. |
