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.
4-38. 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. Maintain a sequential record 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 is 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)
Name of Point of Contact
(4)
Description of Cleaning Performed
