The Welding Smoke Extraction working group in the DMA Air Pollution Control specialist department has completely overhauled the sixth edition of the “Smoke-free welding” guidelines.
These guidelines provide an overview of statutory requirements and measures for air pollution control in workplaces in which work such as welding, cutting and related processes including ancillary work is conducted. The regulations on occupational safety affect the welding processes.
Air pollution control measures are therefore necessary, primarily for occupational safety reasons, but sometimes also for environmental protection. Extracting the emissions where they arise is the most efficient way of detecting the majority of welding smoke emissions and discharging them without them becoming significantly mixed with the ambient air.
The procedure indicates the measures to be taken. Only air handling measures that detect and discharge welding smoke are covered. Aspects such as the welding process, the type of workplace and the size of the pieces to be processed must be taken into account when choosing the measures to take.
The effectiveness of protective measures must be checked; improvements may need to be made and the result documented. The procedure and the respective workplace limits are presented depending on the materials to be processed.
Explanations of the relevant laws, provisions and measures for the necessary waste and disposal specifications, such as the 2012 German Closed Cycle Waste Management Act (Kreislaufwirtschaftsgesetz) and the required fire and explosion protection measures are provided. A list of the relevant laws, provisions and regulations is also included in the new edition.
