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have  both  been  superseded  by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.
