Emissions of hazardous materials by laser beam cutting and milling of fibre reinforced plastics

Laser beam cutting and milling of fibre reinforced plastics leads to high emissions of smoke and dust. For laser beam cutting the health risk is mainly determined by the very high fine dust concentrations, which are completely respirable. Also, the emissions of benzene represent a problem. For milling the problems are caused by the generation of respirable dust but also by dust which may deposit in the trachea region. For milling of aramide reinforced plastics a high risk consists in the emission of respirable fibres.
