Current news from surface technology
Chromium(VI) measurements successfully passed again
In July, the annual measurements of chromium(VI) concentrations in the air during operations in the coating booths took place again. We are obliged to do this in order to maintain our exemption for the use of coating materials containing chromium(VI).
The concentrations in the air are measured in the preparation room, in the area around the coating booths and directly in the coating booths. In addition, we have measurements taken inside the full face masks of the coaters to ensure that the personal protective equipment is working appropriately and that our employees are not exposed to any health hazards. Furthermore, the chromium(V) concentration in the emissions from the exhaust of the coating booths is carried out.
Despite the high workload of the coating department, all measured values were again inconspicuous and the limit values were complied with.
