Abstract:

Three disinfectants, vaporized hydrogen peroxide, 84 disinfectant, and bromogeramine, were used to disinfect different worktables at a biosafety laboratory, and samples were taken at similar locations before and after disinfection. The effects of the three disinfectants on the worktables of a biosafety laboratory were compared. The results showed that 3% hydrogen peroxide was able to disinfect Staphylococcus spp., Escherichia coli and Candida albicans. The number of colonies after disinfection with vaporized hydrogen peroxide was lower than that after the use of 84 disinfectant and bromogeramine, and the difference was significant (F=3.868, P=0.033). The average bactericidal rate of vaporized hydrogen peroxide was higher than that of the other two disinfectants, and the difference was statistically significant (F=3.487, P=0.045). The sterilization efficacy of vaporized hydrogen peroxide is sufficient to replace 84 disinfectant and bromogeramine for use as disinfectants for worktables at biosafety laboratories.

Key words: :vapor hydrogen peroxide, biosafety laboratory, disinfection, worktable
