NIOSH 1983 Feb; :1-7
Ventilation measurements and informal discussions were conducted to evaluate worker exposures to nitrobenzene (98953), pyridine (110861), thiophene (110021), and n-amyl-acetate (628637) at the Center for Molecular Nutrition and Sensory Disorders (SIC-8010) in Washington, D.C. on October 14, 1982. The evaluation was requested by an authorized representative on behalf of three employees. The function of three individuals was to administer smell tests to patients experiencing sensory disorders. Employee symptoms included headaches, nausea, dizziness, and fatigue in two of the testers. Airborne concentrations were well below any criteria, but detectable quantities were present on the hands of two test personnel. The authors conclude that nitrobenzene is probably the cause of the reported symptoms. They recommend the use of disposable gloves and polyseal caps to reduce external contamination of the bottle. They also recommend substitution of benzaldehyde (100527) for the nitrobenzene.
