PIPING IDENTIFICATION
6-2.1
Primary Identification. Identify each valve on a pier, wharf, or drydock
by a plain language brass tag, and labeled. (Example: "potable water" or "sewer".)
Additionally, at each shore-to-ship utility connection, name plates or stenciled letters
near the connection must identify the utility in plain language.
6-2.2
Color Coding. Two sources of design requirements govern color-coding
for pier, wharf, and drydock piping.
6-2.2.1
Distribution Piping On or Under Deck and Ashore. Such piping,
exclusive of shore-to-ship utility connections, must be color coded in accordance with
MIL-STD-101, "Color Code for Pipelines and for Compressed Gas Cylinders".
Applicable requirements must be specified in the design documents.
6-2.2.2
Shore-to-Ship Utility Connections. Such piping (including valves,
operating levers, ends of hose assemblies, risers, and adjacent piping) must be
specified to be color-coded in accordance with Table 6-1. Color-coding may also
extend to adjacent curbs, protective rails, posts, and walls.

OPERATIONAL NOTICES. Provide the following operational notices.
Consult with the Activity and the cognizant NAVFAC EFD/EFA OR USACE DISTRICT
regarding other desired notices, nameplates, warning signs, and so forth.
Bleed systems must be marked with the following warning:
"Freeze protection valve.
Water will flow below 35 degrees F.
