• Description:
  Worker exposures to methylene-bisphenyl-isocyanate (101688) (MDI), fluorotrichloromethane (75694), alpha-methyl-styrene (98839), dimethylcyclohexylamine (98942), triethylenediamine (280579), 2- ethoxyethanol (110805), a proprietory organotin compound, total particulate and carbon-monoxide (630080) were surveyed at John L. Renshaw, Incorporated (SIC-3079) in Beltsville, Maryland, from December 19 to 21, 1979, as part of an industrial hygiene survey of thermal insulation manufacturing and application activities. The Rensulate Division of the company employed 10 workers. The company conducted annual physical examinations and workers were supplied with respirators. Personal and area air samples were collected. Concentrations of MDI were 0.63 and 0.024 parts per million (ppm) for a mechanic and a helper, respectively. Area samples of MDI, dimethylcyclohexylamine, triethylenediamine, fluorotrichloromethane, alpha-methyl-styrene and 2-ethoxyethanol ranged from 0.02 to 0.069, 129ppm, respectively. Concentrations of proprietory organotin compounds and total particulates ranged from less than 5.2 to 38.0 and 4.1 to 6.9 milligrams per cubic meter, respectively. Carbon- monoxide concentration was 5ppm. Concentrations of MDI exceeded the OSHA standard of 0.02ppm. The author recommends engineering controls to reduce concentrations of methylene-bisphenyl-isocyanate. [Description provided by NIOSH]
