• Description:
  A request was received from Local 17, International Molders and Allied Workers Union to evaluate possible hazardous levels of chemical substances in the welding and foundry areas at Wellman Dynamics Corporation (SIC-3321), Creston, Iowa. Crystalline silica (7631869) concentrations in the breathing zone of sand molders, core makers, sand mixers, and core knockout personnel ranged from 52 to 238 micrograms/cubic meter (microg/m3). Formaldehyde (50000) levels of 0.11 to 0.42mg/m3 were found in the breathing zones of coremakers, metal pourers and core knockout personnel, contributing to eye and upper respiratory tract irritation. Triethylamine (121448) was found at levels of 0.4 to 38mg/m3 in the breathing zone of coremakers, increasing respiratory distress. No excess levels were found of aluminum, magnesium, beryllium, inorganic fluorides, barium, methylene-bisphenyl-isocyanate, 1,1,1-trichloroethane, ethyl- alcohol, or ozone. The authors conclude that workers were exposed to potentially toxic concentrations of crystalline silica and formaldehyde. Workers were also experiencing eye and respiratory irritant exposures. The authors recommend the institution of an effective medical and environmental monitoring program, control of free silica dust exposure through engineering methods, medical examinations for workers with possible exposure to silica, and fit testing respirators.
