SMOKE GOGGLES
The smoke goggles were designed for use with the crew mask
assembly, matching the mask face cone. The venting valve, located on
the mask shell and manually actuated by the user, allows direct
communication between venting orifice and goggles.
When mask regulator is selected to emergency position, a metered
oxygen flow will be directed to the goggles' cavity so as to allow
continuous venting and preventing any infiltration of harmful gases.
NOTE: For the Puritan Mask, the purge valve automatically opens
when the smoke goggles are donned.
