• Description:
  An assessment was made of possible exposure to the catalyst dimethylethylamine (75649) (DMEA) at the Winters Industry Foundry (SIC-3321, SIC-3565) in Canton, Ohio in the coreroom sand binder system, in response to a request from the Molders and Allied Workers Union, Local 154. Symptoms of vision disturbances consisting of blurred, foggy or halovision had been reported by workers at the facility along with headaches and stomach pain. Long term personal breathing zone air samples were taken during the core manufacturing processes and revealed the following airborne concentrations: DMEA, nondetectable to 29mg/m3
  
  respirable free silica (14808607), nondetectable to 1,144 micrograms/cubic meter (microg/m3)
  
  methylene- chloride (75092), nondetectable to 4.7mg/m3
  
  perchloroethylene (127184), 2.2 to 6.4mg/m3
  
  1,1,1-trichloroethane (79016), 451 to 764mg/m3
  
  and total reactive isocyanate groups, nondetectable to 144microg/m3. No airborne concentrations of ammonia or nitrosamines were detected. Over 90 percent of the employees experienced at least one symptom or effect which was consistent with DMEA exposure. The authors conclude that a health hazard exists with regard to exposure to free silica. Vision disturbances were considered to be consistent with current and past exposures to DMEA at levels which could jeopardize health. The authors recommend that concentrations of DMEA be kept as low as possible, although there are at present no regulations concerning safe levels of this chemical in the workplace.
