the respirator itself becomes remarkably hot or in the low-temperature
environment where moisture from the exhaled breath becomes frozen.
Deforming of parts or freezing may cause exhalation valve etc. to
malfunction, resulting in leakage of toxic substances into the respirator.
l
Make sure that facepiece is well fit on the face.
Check the fit of the facepiece according to the “Performing fit test” (page 2).
