• Description:
  Painter exposures to isocyanates during painting of process equipment at the E. I. Dupont Sabine River Works, Orange, Texas, were investigated. The evaluation was jointly requested by the International Painters and Allied Trades Union, Local 328, and the painting contractor, Courtney Enterprises (SIC-1721), Houston, Texas. Long term personal breathing zone and area air sampling were performed during painting operations to assess exposures to monomeric hexamethylene-diisocyanate (822060) (HDI) and toluene- diisocyanate (584849) (TDI), total reactive isocyanate groups (TRIG), and organic solvents. Midget impingers, charcoal tube, and silica gel collection devices provided samples for gas and high performance liquid chromatographic analysis. Monomeric HDI was found in two personal samples at concentrations of 5.9 and 23.4 micrograms/cubic meter (microg/m3), and at 41.5microg/m3 in one area sample. Monomeric TDI was found in two personal air samples at 9.3 and 33.8microg/m3. TRIG concentrations ranged from 41.2 to 484 microg/m3. Cellosolve-acetate (111159) concentrations ranged from nondetectable to 63.9 milligrams/m3 (mg/m3). Air concentrations of organic solvents ranged from undetectable to: methyl-ethylketone (78933), 11.4mg/m3
  
  ethyl-acetate (141786), 30.6mg/m3
  
  and xylene (1330207), 9.9mg/m3. The authors conclude that employee overexposures to isocyanates and TRIG were found, while the additive effect of combined exposures to individual solvents could also be hazardous. Use of supplied air respirators was recommended in combination with improved medical placement examinations and general industrial hygiene.
