Abstract
Worker exposures to methylene-bisphenyl-isocyanate (101688), (MDI), fluorotrichloromethane (75694) (FTCM), alpha-methyl-styrene (98839) (AMS), dimethylethanolamine (108010) (DMEA), dimethylcyclohexylamine (98942) (DMCH), triethylenediamine (280579) (TED), and tetramethylbutanediamine (97847) (TMBD) were determined at the Isocyanate Products Division of the Witco Chemical Company (SIC- 2865) in New Castle, Delaware, from October 31 to November 1, 1979. The survey was part of a NIOSH industry-wide industrial hygiene assessment of thermal insulation manufacturing and application activities. The company maintained a formal safety and industrial health program. TMBD, TED, DMEA, and AMS styrene were not detected in any of the air samples. MDI concentrations did not exceed the OSHA standard of 0.02 parts per million (ppm) ceiling limit. FTCM exposures were below the federal standard of 1.0ppm. DMCH was detected in the personal samples of two employees. The authors conclude that the existing precautions observed in this company are adequate to maintain vapor concentrations of materials associated with manufacturing polyurethane thermal insulation products within the limits established by OSHA. They recommend use of safety goggles and the installation of a shower and eyewash station.
