Extreme operating conditions

Low temperatures
If it is not already coated, treat the inside of the visor with "klar-pilot"
anti-misting gel to prevent it from fogging up
visors.
High temperatures/Thermal cycling
If bubbles appear in the visor, it is a sign that the visor is becoming
soft. In this case, leave the danger zone immediately, as the full face
mask can start to leak.
For visors marked PC/CC, the coating of the visor may blister and
come off in places. The function of the full face mask will not be
restricted as a result. It will continue to be usable until the end of the
deployment. Replace the visor after use.
Chemicals
Some substances can be absorbed by the material of the full face
mask or may even diffuse through it. Further information can be
obtained from Dräger.
