Abstract
Abstract : Results of performance testing of commercial air-purifying negative pressure respirators (NPR) are described. A series of tests were performed using human subjects to determine the corn oil protection factors of NPR systems. A series of Protection Factor (PF) tests were performed on 12 commercially available respirators. These tests determined the ability of the respirator to keep small particulates out of the respirator oro-nasal cavity and protect the user from biological warfare agents. The particulates used in the test were made up of a corn oil aerosol. Testing occurred over several weeks, and humans were used as the test subjects. Testing involved a standard series of exercises designed to represent the range of movements that stress the face seals of respirators. All the respirators provided the wearers some protection from the aerosol, and several of them provided excellent protection.
