GENERAL Fume and dust extraction systems are designed on the basis of several criteria. Each individual system is devised to suit the process and the type and characteristics of the fumes. In general, industrial fumes are discharged outside the building in order to comply with the gas exposure values set by CARSAT and INRS (in France) and are also generally filtered to comply with the specifications issued by DREAL in respect of the environment. Machinery for ventilation and for the capture of fumes from welding, cutting, grinding and sanding must take account of two criteria: 1. Pollution...

DATA OCCUPATIONAL EXPOSURE LIMIT VALUES Concentration levels in the working atmosphere and the respiratory tracts of operators that may not be exceeded or occupational exposure limit values (OELV) have been established by the ministry for labour, in order to protect workers’ health (some values are also recommended by the national employees’ healthcare insurance fund: CNAMTS). Occupational exposure limit values are the concentration limits that may never be exceeded in the air inhaled by workers. They are derived from the current scientific data available to specialists about the toxicity...

GENERAL INFORMATION General The pollutants generated by each welding or cutting process are different due to their: ◆ type, ◆ concentration, ◆ and also direction. The capture system must therefore be adapted on the basis of these different criteria. Welding operations. Regardless of the process used, including braze welding, the fumes are hot and therefore naturally rise in the air. Fumes can be captured at source with a fume extraction torch (high-vacuum system) or from the work surface with extraction arms or down-draft tables (low-vacuum system). As a result, fumes are carried away above...
