Vocational Education Training in Environmental Health Sciences: Using Air-Purifying Respirators, Module 9

摘要

In this instructional module, students learn to clean and inspect a dual cartridge, air-purifying respirator, and to perform qualitative fit tests on this type of respirator. Training Prerequisites: There are no prerequisites for using this module. Upon completion of this module, students will be able to perform the following functions: Describe how air flows through an air-purifying respirator, and disassemble an air-purifying respirator and tell how each part works or functions; clean and inspect each part of the air-purifying respirator, and reassemble it for storage or use; and fit an air-purifying respirator so it makes a proper seal on the face, and using a chemical cartridge respirator, test that fit using three types of qualitative fit tests: the positive pressure test, the negative pressure test, and a fit test using isoamyl acetate vapor (banana oil).
