Abstract
Exposures to acetic-acid (64197) vapor in the Maxillofacial Rehabilitation Laboratory, Ellis Fischel State Cancer Hospital (SIC- 806), Columbia, Missouri were investigated. The department director requested the study, which was performed on December 15, 1981. At the time of the study two workers were employed at the laboratory in the construction of maxillofacial prostheses which released acetic- acid during curing. Fifteen minute average exposures to acetic-acid were about 4 parts per million (ppm) for one worker while exposures ranged from 4 to 30ppm for the other. The American Conference of Governmental Industrial Hygienists recommends that exposures not exceed 15ppm during any 15 minute sampling period. Irritant effects have been reported to occur at concentrations below 10ppm. The author concludes that eye and nose irritation due to exposure to acetic-acid vapors occurs during prosthetics fabrication. A small fan near the work desk of the affected employee is recommended to direct acetic-acid vapors away from the face.
