Unless otherwise indicated, these guidelines are not intended to restrict or replace professional judgment.  \nRelated Sections  \nRelated References  \nIn general it is the University’s intention to follow industry practice, and to use existing standards to establish these guidelines.  \n• ANSI A13.1-Scheme for the Identification of Piping Systems  \nPiping and Ductwork Identification  \nAll pipes in all exposed locations shall be identified with factory fabricated, precurled labels securely attached to the pipe. Film markers are not acceptable, as they tend to wear off with time. Ductwork mains and all fume hood exhaust ductwork require labeling.  \nClearly identify direction of flow in piping and ductwork with arrows. Arrows and markers shall be mounted to provide unobstructed visibility from floor level.  \nPipe and Ductwork labels should indicate full name of service as indicated below. Abbreviations should be used on drawings only.  \nPipe Labeling  \nPipe labels should be installed at all access panels or doors, adjacent to valves and branch connections, both sides of floors, ceilings and walls, all major changes in direction, on straight lengths of pipe every 25 feet, and at points of termination (except in occupied spaces) .  \nIdentify contents of piping system by both fluid contained and unique temperature and/or pressure (if necessary to distinguish between other systems with same fluid at different conditions); e.g., Potable Hot Water-110oF vs. Potable Hot Water-140oF.  \nPlumbing and Waste Pipe System Labels  Drawing I.D.
