(2) A component that has been "in service" may have visible signs of grease, dirt, etc.
(3) Absorption of oil or grease on a clean filter paper from a surface swipe.
b.
Ultraviolet Light Method. The ultraviolet method for detecting hydrocarbons may be employed in several
different ways.
WARNING
MOST ULTRAVIOLET LAMPS CONTAIN MERCURY. EXTREME CAUTION SHOULD
BE TAKEN NOT TO BREAK THE MERCURY VAPOR LAMP WHICH WILL
CONTAMINATE THE COMPONENT OR PIPE BEING INSPECTED AND MAY ALSO
CAUSE HUMAN INJURY.
(1)
Direct Inspection: The component may be examined directly with the ultraviolet light. By passing the
component under the ultraviolet light, hydrocarbon surface contamination may exhibit fluorescence where
some hydrocarbons exist.
(2)
Inspection of Cleaning Solution When Detergent is Used: Used cleaning solution collected in a clean
beaker when agitated will form bubbles. These bubbles, under ultraviolet light, may exhibit fluorescence.

Documentation and Record Keeping.
a.
All diving systems currently involved in U. S. Army diving operations require that they be certifiable. It is with
this requirement understood, that a diving system must retain certain records and documents to substantiate safety
standards. The individual operating the clean area being directly involved with system maintenance should therefore be
required to maintain records documenting cleaning operations in a systematic manner.
b.
The purpose of this section is to set forth a guide for documentation and record keeping involved in cleaning
operations and in no way intends to impose restrictions on the amount of paperwork a unit feels It requires to operate
safely.
c.
A sequential record maintained of components cleaned (i. e. regulators, pipe, and/or any component) affecting
re-entry into a certified system. It should include a written record of all cleaning analysis and testing accomplished as per
this procedure. A data sheet should be completed for items cleaned and tested per this procedure. All other information
which pertains to the cleaning and/or testing of a particular item shall be attached to or referenced on the data sheet.
Such information should include, but not limited to outside laboratory reports, vendor data, etc.
d.
It is possible that certain data and results will apply to more than one data sheet. For example, it is possible that
a sample for gaseous contaminants will be taken by sampling an entire system. This system will consist of numerous
items, each having its own data sheet. To assure complete documentation, reference the results of the gaseous
contamination analysis on each affected data sheet.
e.
As a minimum the data sheet should reflect the following information:
(1) Unit
(2) Date
3-188
