Workplace analysis according to TRGS 402 (German Technical Rule on Hazardous Substances)
Gefahrensymbol toxisch.

The group „Safety Technology“ carries out workplace analyses for laser material processing and laser workplaces according to the German Technical Rule on Hazardous Substances 402 (TRGS) and to the German Hazardous Substances Ordinance (GefStoffV). 


In the companies, person- and site-related exposures to hazardous substances (gases and fumes) at laser workplaces are determined as time-weighted average. Afterwards, these values are compared to the relevant Occupational Exposure Limit Values (OELV). Based upon the results, the company can establish adequate protective measures.

The used sampling and analysis techniques comply with the regulations.
