installed. When replacing insulation, make
certain that the replacement material is of
the same type as had been used originally.
7. Insulate all flanges with easily removable
forms. These forms are made up as pads
of insulating material, wired or bound in
place, and the whole covered with sheet
metal casings, which are in halves.
8. Asbestos control: Inhalation of excessive
quantities of asbestos fibre or filler can
produce severe lung damage in the form of
disabling or fatal fibrosis of the lungs.
Asbestos has also been found to be a casual
factor in the development of cancer of the
membrane lining the chest and abdomen.
Lung damage and disease usually develop
slowly and often do not become apparent
until years after the initial exposure. If
your plans include a long and healthy
Navy retirement, you have no business
doing asbestos lagging rip-out without
proper training, protective clothing, and
Most systems of todays
modern Navy have been purged of asbestos
and an asbestos substitute material installed
in its place. Some of the older class vessels
may still have some asbestos insulation
installed. Use caution when handling
lagging and insulation from these vessels.
If in doubt, contact your supervisor and
request the medical department conduct a
survey of the material in question.
This chapter has given you general informa-
tion on pumps, valves, and piping. It would be
a good idea to get some hands-on experience
aboard your ship. Trace various systems out and
see how they are set up. Ask your LPO to explain
the systems and how each part in the system
works. The key phrase here is ASK QUESTIONS!
