Richard Hall & Associates



Air Quality

The client operated a fabrication business. One particular repetitive job was carried out from time to time in different places in the factory. The welding electrodes used for the job were particularly smokey requiring use of a respirator by the welder.

Richard Hall & Associates investigated the reasons why the job was carried out in differing locations and devised a system which allowed it to be carried out at a fixed station with appropriate work piece handling. This in turn allowed the use of a standard welding fume extraction unit to remove the welding smoke. The resulting fume levels were monitored to verify that they were reduced below acceptable thresholds so that the operator no longer needed to use a respirator. The general atmospheric conditions in the fabrication shop were noticeably improved.
