seal, readjust head harness straps and repeat test until there is no leakage. If other facial seal leakage is detected, the condition must be investigated and corrected before another test is made. NEGATIVE PRESSURE FIT OR SEAL CHECK: Lightly place palms over cartridges of filter holders. Gently inhale and facepiece should collapse against the face. The respirator must pass the tightness tests before the respirator is used. REPLACING THE CARTRIDGES AND FILTERS The following conditions are indications that the cartridges or filters have served their useful life and should be replaced. CARTRIDGES: Odor or taste of gases or vapors, eye, nose, or throat irritation, or at a frequency indicated by the ESLI or by scientific data. FILTERS: Excessive breathing resistance or odors (where present) upon inhalation. To replace cartridges proceed as follows: Remove the expended cartridge an discard Remove the replacement cartridges from storage bags and insert into the threaded receptacles making sure gaskets are in in cartridge holders. Carefully hand tighten the cartridges to prevent damage to threads and to insure a good seal against the gaskets. CLEANING AND SANITIZING The face piece (with the cartridges removed) should be cleaned and sanitized after, every use with a suitable cleaner/sanitizer, such as MSA Cleaner-Sanitizer, Part No. 34337 or other, such as 50 ppm chlorine or iodine. Make a solution with the contents of one package added to water, following the instructions on the cleaner-sanitizer carton. Immerse soiled equipment in the solution and scrub gently with soft brush until clean. Take care to clean the exhalation valve in the face piece and other parts that exhaled air contact. in plain warm water (about 110°F) and then air dry. Cleaning and sanitizing at the recommended 110°F, temperature will avoid possible CAUTION: overheating and distortion of parts of the respirator assembly, which would necessitate replacement.
