| Abstract: | Methods of validation of formaldehyde decontamination of biological safety cabinets were compared. Decontamination of metal strips inoculated with Mycobacterium bovis, poliovirus, or Bacillus spp. spores was compared with the results obtained with three biological indicators. Conditions for successful decontamination, particularly relative humidity, were defined. The Attest 1291 biological indicator was the only biological indicator which was an aid in the detection of gross decontamination failure. |
