Development on a disinfection cabinet for positive pressure biological protective hood and observation of its disinfection effect
Objective To develop a disinfection cabinet for positive pressure biological protective hood and assess its disinfection effect.Methods The simulated field and qualitative disinfection test were used to observe the disinfection effect of the biological protective hood disinfection cabinet.Results After UV irradiation for 120 min on positive pressure biological protective hood disinfection cabinet,the number of survival quantity of Bacillus subtilis var.niger on the surface of protective hood and stainless steel were less than 1 cfu/mL.The Bacillus stearothermophilus spores on inside and outside of the positive pressure hood and on the inner surface of the cabinet were effectively killed by external hydrogen peroxide generator.Conclusion The disinfection effect of cabinet to positive pressure biological protective hood is able to meet the requirements of biosafety.
