Facepiece-to-face leakage evaluation using a helium leak detection method
This paper presents a simple method of using physiologically inert helium as a diluant in a respirable mixture of air, and then detecting the amount of helium leaking into the respirator facepiece with a mass spectrometer helium leak detector equipped with a special sampling and calibration system.
