scope:

This Standard specifies the performance, structure and material requirements, as well as the test methods of Class II biological safety cabinets. A Class II biological safety cabinet includes an exhaust duct and a remote blower connected to it, if any. This Standard is not applicable to classic type Class II cabinets in which the positive pressure contaminated plenum is directly in contact with the outer wall.

WARNING 1

Users of Class II biological safety cabinets shall have sufficient knowledge regarding the handling of pathogenic microorganisms and the handling of Class II biological safety cabinets, and in operating the cabinet, shall follow the directions given by a person in charge of or responsible for biohazard safety. This Standard is not intended to address all the safety problems associated with its use.

WARNING 2

The clean work station, in contrast with Class II cabinet, is an apparatus designed to send clean air to the work space and to prevent the treated sample from being contaminated, and is not intended for ensuring personnel or environmental safety against biohazards. Although the two apparatuses resemble each other in appearance, airflow and structure, a clean work station should never be used in works requiring biohazard safety measures.

NOTE 1 The Class II biological safety cabinets, as referred to in this scope, are the safety cabinets satisfying the requirements established by the Minister of Health, Labour and Welfare based on the Regulation for Enforcement of the Act on the Prevention of Infectious Diseases and Medical Care for Patients with Infectious Diseases [Order of the Ministry of Health and Welfare No. 99 of 1998, 2 of Article 31, item (x)]. They are also safety cabinets stipulated in the Regulation for Enforcement of the Act on Domestic Animal Infectious Diseases Control (Order of the Ministry of Agriculture and Forestry No. 35 of 1951, 8 of Article 56) and also the research purpose safety cabinets stipulated in the Act on the Conservation and Sustainable Use of Biological Diversity through Regulations on the Use of Living Modified Organisms (Act on "Cartagena") (Act No. 97 of 2003) and the Ministerial Order Providing Containment Measures to be Taken in Type 2 Use of Living Modified Organisms for Research and Development (Order of the Ministry of Education, Culture, Sports, Science and Technology and the Ministry of the Environment No. 1 of 29 January 2004).
