GENERAL MAINTENANCE GUIDANCE
3.9.1
Lubricants and Sealants.
Maintenance personnel
must ensure that lubricants and sealants introduced into the
hyperbaric facility are suitable for use in high pressure air and
oxygen environments.
Lubricants and sealants used shall be
selected from the tables listed in NAVFAC DM-39, Chapter 12.
3.9.2
Chamber Painting. Only steel chambers are painted.
Aluminum chambers are normally a dull, uneven grey color and
corrosion products can be easily recognized. Painting an aluminum
chamber will hide and further encourage corrosion. Steel chambers
shall be painted as delineated per NAVFAC DM-39, Chapter 8. (Note:
MIL-E-17970
and MIL-E-17972
have both been superseded by
DOD-E-24607).
3.9.3
Piping Color Code and Labeling. Hyperbaric facility
piping and tubing must be color coded and labeled to indicate
contents, function, direction of flow and possible hazards. Piping
color code and labeling shall comply with the requirements of
NAVFAC DM-39 Chapter 5.
