Quantitative fit test methods for respirators.

• Description:
  Methods which are currently used or which have been considered for use in the United Kingdom for the testing of the quantitative fit of lung powered respirators are reviewed. The advantages and disadvantages of the current test method, which uses sodium-chloride (7647145) aerosol as the test agent, are discussed. Methods which can be used for the testing of disposable valveless facemasks are described. Improvements to the British standard test method, which includes testing subjects who are on a treadmill and performing various exercises, are reviewed. The use of alternative agents, including argon (7440371) and Freon-12 (75718), for the measurement of facial fit is discussed. The development of a method suitable for measuring the facial fit on every worker using a personal respirator is reported. The author concludes that the measurement of the facial fit of respirators should be carried out in a manner which at least attempts to simulate realistic conditions of wear and that the sodium-chloride aerosol method appears to be the best available method for routine testing.
