Abstract This revised guidance note (see CIS 88-952 for previous edition) describes the important features of good local exhaust ventilation (LEV) systems in order to assess their effectiveness and performance. It is stressed that all means of controlling contamination should be considered before a local exhaust system is designed, so that the most effective degree of control can be achieved. Contents: the generation of airborne contamination; assessing the hazard; inlets to LEV systems; partial enclosures; hoods; ductwork; airflow distribution and balancing; air cleaners; fans and air movers; discharge to the atmosphere; commissioning and maintenance; examination and testing of LEV systems; legal requirements.
