2. All samples are tested for solids by being spun
in a centrifuge. Solids will settle at the bottom of the
sample.
3. Allowable “use limits” are tested and recorded.
When the physical test is completed, the
shipyard/IMAs will make a spectrometric analysis of
each used oil sample, then report to all concerned the
concentrations of the following elements in parts per
million (ppm).

POTABLE WATER SYSTEMS
The potable water system supplies scuttlebutts,
sinks, showers, sculleries, and galleys and provides
makeup water for various freshwater cooling systems.
This system is often called the freshwater system. The
term fresh water is not correct because fresh water is not
potable unless it is safe for human consumption.
Potable water may be contaminated during
production, handling, storage, or distribution. Treatment
with a halogen, such as chlorine or bromine, is the only
approved method of disinfecting potable water.
Submarines and servicecraft are not equipped to use the
halogen treatment method. They are provided with
emergency methods to treat fresh water. The ship’s
engineering and medical departments are responsible
for the receipt, distribution, and quality testing of
potable water. For more in-depth information
concerning potable water systems, refer to NSTM,
Chapter 533, “Potable Water Systems.” Additional
references related to potable water systems are shown

TRAINING
By the time you have reached the EN2 level of
experience, you have acquired many skills and a
considerable amount of theoretical knowledge. As an
EN2, you will be responsible for passing these skills and
knowledges on to other, lower-rated Enginemen.
Success in training others requires that you have or
develop certain additional skills as an instructor.
TRAINING RESPONSIBILITIES
You must be technically competent before you can
teach others, but your technical competence must be
supplemented by the ability to organize information, to
present it effectively, and to arouse and keep the interest
of your trainees.
You will find excellent general information on how
to plan, carry out, and evaluate an instructional program
in Military Requirements for Petty Officer Second
Class, NAVEDTRA 12045, and in Military
Requirements for Petty Officer First Class, NAVED
TRA 12046.
Our discussion does not include the basic
information given in these references. Instead, it deals
with some of the difficulties peculiar to the training of
the engine-room and auxiliary personnel and some of
the ways in which you can overcome or minimize these
difficulties.
What kinds of things cause special problems in the
training of engine-room personnel? For one thing, the
interrelationship of propulsion plant operations. Each
person must be trained to perform not only as an
individual but also as a member of a team. Take for
instance the duties of the watch standers. They are very
closely related, and the actions taken by one person
depend in some way upon the actions taken by other
persons. From a long-range point of view, however, the
teamwork required for engine-room operations can
actually be turned to a training advantage. As a person
is being trained for one specific duty, he or she will
naturally learn something about the other duties. As a
rule, therefore, the first part of a person’s engine-room
training may take quite a while, but the last part will take
much less time.
