摘要
A process (100) for deactivating a fume cupboard (10) is provided. The fume cupboard comprises an open front section (15) which is closable by means of a front sash (17), a work chamber (13) enclosed by side sections (16), a bottom section (18), a back side section (14), and a top section (20) provided with an exhaust opening (22). The fume cupboard further comprises an electrical power measuring unit (44) configured to measure electrical power consumption of the fume cupboard. The process comprises the steps of determining (102), by means of the electrical power measuring unit, if an electrical power consumption of the fume cupboard fulfills a predetermined threshold condition; if so, closing (201) the front sash of the fume cupboard; switching (203) an electrical power for the fume cupboard off; and controlling (204) an air flow through the fume cupboard to a minimum flow.
