Title Health hazards due to the machining of high-alloy steels
Original title Gefährdungen beim Bearbeiten hochlegierter Stähle [in German]
Bibliographic information Feb. 2003, No.2, p.46-47. Illus.
Abstract Welding of high-alloy steels, in particular V2A steel, produces smoke that contains chromium (VI) and nickel (V) compounds, which are carcinogenic. Since this type of job is often subcontracted and because there are wide differences in the working conditions of welders, an evaluation of welders' exposure to this type of smoke was carried out using the example of a small boat galley, with and without exhaust ventilation. Ambient measurements show that whatever the ventilation conditions, permissible levels cannot be complied with consistently. The article emphasizes the need to make respirators available to the workers and to ensure, whenever the work is subcontracted, that the contractors comply with existing legislation, since the occupational safety and health responsibility remains with the principal.
