The Class I microbiological safety cabinet - en12469 2000 definition: 'Safety cabinet with a front aperture through which the operator can carry out manipulations inside the cabinet and which is constructed so that the worker is protected and the escape of airborne particulate contamination generated within the cabinet is controlled by means of an inward airflow through the working front aperture and filtration of the exhaust air'. The class I microbiological safety cabinet provides a robust wide performance envelope for the user from aerosol hazards and other particulate matter within the cabinet's working area. All extract air is exhausted through hepa (high efficient particulate air) filtration generally to atmosphere although recirculation models are also available. Inflow air velocity should be between 0.7 and 1.0 m/sec and by their design nature are less susceptible to poor working techniques of the user or less than ideal room air conditions although this is no excuse for either. Safety Cabinets Solutions stress, neither poor site conditions or poor techniques should be tolerated in the modern safety conscious laboratory environment. The class I msc is very much a UK cabinet with most of the rest of the world preferring the more versatile class II msc. We recommend that all msc are sited in accordance with BS5726 2005 safety cabinet recommendations
The class I microbiological safety cabinet provides assured, reliable user protection but no protection for the sample material in the cabinet. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
