Safety at laser welding

TBH GmbH currently offers the worldwide largest range of DGUV approved mobile welding fume systems in accordance with valid guidelines DIN EN ISO 15012-1 and DIN EN ISO 15012-4.

STRAUBENHARDT – Do you process various materials in your production line with a laser? Is it set up in your offices? The lawmaker and the Employer’s Liability Insurance Association demand using filter and extraction systems for thermal processes. These filtrate the very harmful hazardous substances, which different processes cause, from the ambient air. High safety standards are valid for the employee’s health protection during welding and similar processes such as laser welding, cutting and marking.

These applications let arise chromium IV particles, which are demonstrably carcinogenic. The lawmaker has set strict guidelines to eliminate these pollutants safely and effectively from the air. In accordance with TRGS 528, only extraction systems, which carry the seal „approved against hazardous substances according to welding fume efficiency class W3”, are allowed to use for these processes. If not all operating systems carry this seal, an inspection will cause the shutdown of the production line.

In accordance with the German Occupational Safety and Health Act, the percentage part of dangerous fumes and gases in the air cannot exceed defined limit values. These depend on the harmfulness of each contaminant. Gaseous and particulate hazardous substances within welding fume are respirable. Inhaled chromium expositions are so small that they can penetrate the alveoli and settle there.

As a manufacturer of filter and extraction systems, TBH GmbH currently offers the worldwide largest range of DGUV approved mobile welding fume systems in accordance with valid guidelines DIN EN ISO 15012-1 and DIN EN ISO 15012-4. These meet the required protection level in accordance wih TRGS 528. In reference to that, the TRGS 560 regulate the requirements concerning air return when operating with carcinogenic contaminants. The thermal processing of nonmetal material releases harmful particles in nanoscale as well. To assure reaching the highest possible safety goals for people, environment and machinery, we suggest using TBH filter and extraction systems carrying the “DGUV test seal”.
