• Description:
  Sampling surveys of the welding operations were conducted at United Air Specialists, Inc. (SIC-3564), an air cleaning equipment manufacturer in Cincinnati, Ohio. Approximately 30 welders were employed at the facility which operated on a 4 day, 10 hour/day work schedule. No exposures were noted in excess of the OSHA Permissible Exposure Limits for either total particulate or for any sample fume constituents for the air sampling measurements collected on welders, a cutter, and a grinder. Air contaminant levels were higher during the cutting operation than during other tasks. Use of a local exhaust system during cutting was not able to completely control the dust and fume exposure. Canopy hoods appeared to effectively control the welding fume exposures, but it was suggested that short term exposures may occur which were not accounted for in these monitoring techniques. The ventilation system used in this study had the drawback that the position of the canopy hood to the part being welded on may result in the welding fume passing directly into the breathing zone of the welder prior to being exhausted. The authors urge all managers to be certain that welders keep their heads out of the welding plume at all times.
