(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.
4-60. Documentation and Record Keeping.
a. This 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 should be maintained of components cleaned (i.e., regulators, pipe, and/or any component)
affecting reentry into a certified system. It should include a written record of all cleaning analyses 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 be limited to outside laboratory reports, vendor data, etc.
The completed data sheet(s) will then be attached to the REC Report and referenced in the remarks column on the
Reentry Control Log
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
(5) Person Performing the Cleaning
(6) Results of any Analysis
(7) Description of Item Being Cleaned
(8) Part Number/NSN
(9) Remarks
