• Description:
  Engineering controls which may be used to reduce the exposure of workers to fumes during welding operations were evaluated at Cleveland Range, Inc. (SIC-3556), Cleveland, Ohio. The facility manufactured steam ovens. Fume extraction guns were used to control some of the exposure. Welding processes used included gas metal arc welding, gas tungsten arc welding, and flux cored arc welding. The NIOSH Recommended Exposure Limit and the American Conference of Governmental Industrial Hygienists Threshold Limit Value (TLV) levels were exceeded for iron (7439896), manganese (7439965), or nickel (7440020) on various occasions. For the flux cored arc welders, all four exceeded the TLV level of 0.2mg/m3 for manganese and one exceeded the 0.015mg/m3 level for nickel and the 5mg/m3 level for iron-oxide (1309371). The gas metal arc welders were exposed to nickel at levels exceeding 0.015mg/m3. The ventilation system did reduce exposure levels, but not to recommended limits. The usefulness of the extraction system to capture welding fume was adversely affected by using overhead and standing fans in the welding areas.
