Biosafety
Cabinets - The open fronted class I and II cabinets must be sited carefully. They should not be used if persons are moving around in the laboratory because draughts created by persons moving past a cabinet can draw the particles out of the cabinet.
Air from the safety cabinets should not be discharged near ventilations or open windows. Centrifuges and other similar instruments which may produce gross splashes or particles should not be kept in the cabinet as the air flow pattern can not prevent the escape of such gross splashes.
