Air sample analyses and medical evaluations of workers were performed at Bob Gerren Ford, Incorporated (SIC-5511) in Manistee, Michigan on August 22 and 23, 1979. The request was received from management to evaluate reports of fatigue, headache and respiratory symptoms among employees. Air sample analysis for acrolein (107028), and formaldehyde (50000) was negative. Toluene- diisocyanate (26471625) (TDI), methylene-bisphenyl-isocyanate (101688) (MDI), and naphtha (8030306) were detected in quantities 10 to 100 times below the OSHA standards of 0.14, 0.2, and 400 milligrams per cubic meter, respectively. Heating of urethane foam insulation samples from the ceiling of the truck bay produced formaldehyde and TDI only at temperatures of 120 degrees F. Health and occupational history questionnaires and medical histories of the owner and 11 employees indicated fatigue in 11 and headache in 7 individuals. Cases occurred with equal frequencies in all areas of the facility. The authors conclude that even though the contaminants were present in quantities below the recommended OSHA standards, trace concentrations of TDI and MDI can produce illness in sensitized individuals. Since air sampling was performed when the facility was not operational, results may not have adequately reflected the environmental conditions during workdays.
