WKPP - Approved Gases
by Casey McKinlay and George Irvine
These gases are for use in the WKPP and are not to be
confused with anything else outside of the WKPP.
They reflect MINIMUM helium requirements and MAXIMUM oxygen
requirements.
See the other sections of this web site for more explanation and
detail.

*** 190 gas gets dropped when 190 is
reached.
There are no 190 profiles in the WKP - all caves are deeper or
shallower than that.
For caves where the depth is expected to stay beyond 150 feet other
than in a slope to depth,
the helium in the 190 gas needs to be pushed up accordingly.
Gas choices for profiles beyond the expected
must be approved
by both the Project Engineer and the Project
Director
