Zusammenfassung:A safety cabinet (1) is portable and comprises a main housing (4) supported on a support housing (5). The main housing (4) defines a substantially spherical working chamber (18) within which the negative pressure is created and within which tests or experiments may be carried out. A fan (51) draws air through a main filter (63) through ducts (56) and (54) from the working chamber (18) and delivers the filtered air through a conduit (58) and an exhaust outlet (50). Access openings (23) provide hand access to the working chamber (18). The main housing (4) comprises a pair of substantially hemispherical shells (6) and (7) of transparent plastics material joined by a hoop (16) which engages flanges (9) and (15) of the shells (6) and (7).
