Abstract
Levels of acetic-acid (64197) vapor, emitted during polymerization of Silastic Medical Adhesive Type-A, were determined in air samples from an 840 cubic foot suite used for maxillofacial prosthetics. The acetic-acid vapor levels to which the operator and the assistant were exposed were measured using gas chromatography (GC). Additional measurements of operator exposure were made using direct colorimetry. Personal breathing zone concentrations of acetic-acid vapor were found to be 4 and 0.7 parts per million (ppm) for the operator and for the assistant, respectively, when analyzed by GC; the concentrations ranged from 4 to 30ppm when analyzed by direct colorimetry. The authors conclude that the use of Silastic Medical Adhesive Type-A in the fabrication of facial prostheses may cause health hazards to the patient and the operator because of acetic- acid emission.
