AS 2252.2-1994

Specifies requirements for laminar flow cabinets intended to provide protection from hazardous biological agents for personnel, the environment and to protect material used in the cabinet from contamination. Construction, air characteristic, acoustic, lighting and vibration requirements are given.

This Standard specifies requirements for Class II laminar flow biological safety cabinets which are intended to provide protection from hazardous biological agents for personnel and the environment and also to protect material used in the cabinet from exogenous contamination. The cabinets provide protection by inducing an inflow of air through the work access opening, by delivering recirculated, filtered, laminar flow air downwards through the work zone and by high efficiency particulate air (HEPA) filtration of exhaust air.This Standard should be read in conjunction with AS 2647 which describes recommended practices for installation and use of these cabinets.NOTES:1 These cabinets are intended only for handling materials which can be neutralized or rendered safe by an effective decontamination procedure such as that described in AS 2647.2 Additional design requirements may apply to cabinets which are required to afford protection against other hazards such as toxic materials not of biological origin or against radiation.3 For work with cytotoxic drugs the user is referred to AS 2567.
