A. An employer spent €30,000 on installing moveable hoods in his welding workshop. However, the workpieces were large and would have required a second person to move the hood in order for the welding fume to be removed as the Welder was welding the length of the workpiece. This was not possible so the employees could not use the LEV. On-tool extraction and RPE would have been a better choice.
B. The supplier of the LEV installed the exhaust points beside the intakes vents. This resulted in the contaminants re-entering the workplace.
C. Employer was using a thoriated tungsten electrode. They reviewed the process and were able to change to a alternative tungsten electrode thus eliminating the associated hazard.
