Occupational health
Suitable fume extraction devices are required for semiautomatic brazing jobs and if necessary torches with integrated fume collection should be used. In case that seams need to be ground off the maximal permitted values for fine dust must be obeyed. Suitable dust extraction devices have to be installed in such areas.
Due to occupational health and economic production a formation of Zink oxide flakes (white deposit on the work piece or floating particles) must be avoided by reduction of the heat input.
