Abstract A document produced by the collaboration of ventilation and chemical safety specialists with trade unions. It is a guide and reference document for the design and operation of installations for the trapping or dilution of pollutants. Contents: review of the process of knocking out castings and of the principles of ventilation in general; design of collecting devices (choice of configuration, dimensions, calculation of capacity); qualitative and quantitative monitoring of a ventilation system (methodology, equipment and timing of monitoring). Examples of calculations from real studies are given. An appendix includes a list of the main pollutants associated with different processes, air flow rates for tumbling barrels, and systems for distributing air flow at openings.
