4.3

Donning the facepiece

The sealing surface between head and full face mask must be free of hair
and foreign objects as these could cause leakages. Spectacle wearers should
wear mask spectacles.
● If required, insert the mask spectacles.
● Open the head harness as far as it will go (see fold-out page, Figure C).
At extremely low temperatures, the wearer should hold his breath briefly
when donning the face mask. This prevents the inside of the visor from
fogging up.
● Release the full face mask from the standby position.
● Pull the harness apart, then put your chin into the chin cup.
● Pull the head harness over your head and draw it backwards.
● Adjust the full face mask.
● Pull the straps until evenly tightened; first the neck straps, then the temple
straps, finally the front strap.

Checking for tight fit

If pad particle filters are used, only perform the overpressure test, since the
pad cap does not seal the gas filter or pad plate airtight.
Negative pressure test (see fold-out page, Figure D)
● Seal both respiratory filters with your hands or an aid (e.g. a nearly flat piece
of cardboard) and breathe in until a negative pressure is generated. Hold
your breath for a moment. The negative pressure should be maintained. If
not, retighten the harness.

Overpressure test (see fold-out page, Figure E)
● Seal the exhalation valve of the full face mask and breathe out forcefully.
The full face mask must not lift off your face. If breathing air escapes
through the sealing frame, retighten the harness.
CAUTION
► Make sure that the full face mask is perfectly tight and the respiratory filters
are fitted before entering the contaminated area.
If the suitability of the mask for use is impaired by application-specific
influences, leave the danger zone immediately.
