Do you know the contents of this pipe? Or that one?
Having facility pipes clearly marked with compliant labels allows plant staff, maintenance crews, and emergency workers to quickly identify pipe contents and flow direction.
ANSI, or the American National Standards Institute, uses this color code to identify pipes by the general kinds of materials they contain.
Yellow is flammable, brown is combustible, orange is toxic and corrosive. Red is fire quenching, green is other water, blue is compressed air- and other colors, such as black, grey and purple should be determined by the facility's needs.
