ASME/ANSI A13.1 2015 standard recommends the use of GHS pictograms as part of the pipe marker legend, ideally to communicate hazard information. Seton offers easy-to-adhere vinyl markers that, when used with our arrows-on-a-roll tape, comply with this new optional specification. To apply, simply peel off the liner and stick the marker to the pipe. These are ideal for clean, dry surfaces both indoors and outdoors and temperature ranges of -40°F to 180°F.
