Centro de Documentacion de Fundación MAPFRE - Biological safety cabinets : decontamination or sterilization with paraformaldehyde

Notes: Sumario: Bacillus subtilis var. niger spores were used to determine the exposure time for formaldehyde decontamination of biological safety cabinets. Formaldehyde contact times less than 3 hr were insufficient for sterilization. A contact time of 4 hr or more resulted in a reproducible killing of the spore strips placed inside the cabinets. At 6 hr sufficient formaldehyde had diffused through the high efficiency particulate air (HEPA) filter to sterilize the strips with lower spore counts. A minimum of 5 to 6 logs of killing were observed after 4 to 6 hr of treatmentRelated records: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 49, nº 6, June 1988 ; p. 277-279Materia / lugar / evento: Higiene industrial Contaminantes químicos Contaminantes biológicos Formaldehido Esterilización Recintos cerrados Otros autores: Fink, Richard
