Abstract
This study was designed to demonstrate that organic solids are able to penetrate materials used in protective clothing when in direct contact with the materials, and to evaluate the apparatus used to conduct permeation studies with organic solids. The solids tested included p-dichlorobenzene (106467), 4,6-dinitro-o-cresol (534521), 2,4-dinitrotoluene (121142), quinone (106514), camphor (76222), naphthalene (91203), hydroquinone (123319), phenol (108952), and p- nitrotoluene (99990). The glove materials tested included natural rubber (latex), polyvinylchloride (PVC), urethane, nitrile, and neoprene membranes. The measurement system used a stainless steel exposure cell which allowed rapid uniform contact of solid disks or powders with the material. To monitor the permeation process a gas chromatograph was used which was equipped with a flame ionization detector having limits of 0.9 to 1.2 nanograms for the organic solids tested. Breakthrough times, steady state times and steady state permeation rates (SSPRs) were determined for the five materials exposed to the nine compounds. Permeation by the solids exhibited the same general permeation curve as has been demonstrated for liquids. Breakthrough times ranged from 2 minutes to 8 hours for the five materials and most of the nine chemicals, with most of the breakthrough times being less than 10 minutes. The breakthrough time variability ranged from 0.43% for p-nitrotoluene with latex to 8.5% for dichlorobenzene with nitrile. Of the materials tested, neoprene and nitrile exhibited the lowest SSPRs; SSPRs of up to 8.1 micrograms/minute/square centimeter were noted.
