b'What You Need to KnowMarking and identification of contents in pipes and piping systems is important to safety and maintenance. Pipe markers are used to visibly identify contents, flow directions, and hazard classification, thus promoting a safe working environment . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .A LEGENDD MATERIALS The legend on the marker gives the name of the contents inChoose the correct material to fit the application. full or abbreviated form.
