GHS Pipe Markers - Stick-On Labels
ANSI / ASME A13.1 2015
Additional Means of Identification ASME A13.1 2015
ASME A13.1 has incorporated the GHS pictograms into the new 2015 revision and has recommended their use as part of the legend.
"The applicable GHS pictogram as illustrated below may be included as part of the legend. Where piping is connected to containers that are labeled in accordance with GHS requirements, a corresponding label on the piping may be provided. The corresponding label should contain at least the product name or identifier, the pictogram, the signal word, and the physical, health and environmental hazard statements."

Hazard Communication Pictograms
Nine OSHA approved Hazard Communication pictograms. Each pictogram below is used to alert users of the chemical hazards to which they may be exposed to. The pictogram consists of a black symbol inside a white diamond framed by a red border and each represents a distinct hazard. From no symbols, or up to 6 different symbols can be printed on each marker, depending on the substance you need to identify. The symbol printed on the marker is determined by its chemical hazard classification. Reference the company's SDS sheets to learn about the hazard classification of each substance you will be exposed to.

- Self adhesive markers you peel and stick
- Brimar's specially formulated adhesive is applied with a heavy coating to ensure adhesion to a variety of surfaces.
- Markers should only be applied to clean and dry surfaces.
- Durability: 4 to 5 years outdoors Mid Continental US
- Service Temp: -20° F (-29°C) to 200°F (93° C)
- Minimum Application Temp: 50° F (10° C)
- Surface Prep: Clean & Dry
- Compliance: ANSI / ASME A13.1 2015
- Markers comply with the new ANSI / ASME A13.1 2015 standard if used in conjunction with arrows.
Marker Size, Letter Height and Maximum Characters per Marker
The following chart shows the recommended pipe marker letter height and marker size based on the outside pipe diameter of the pipe to be identified. For pipes smaller than 3/4" and for valve identification, the use of a permanent legible tag is recommended.
Pipe O.D. | Text Size | Marker Style | Maximum Characters |
---|---|---|---|
3/4" - 1-1/4" | 1/2" | 1XSM | 22 |
1-1/2" - 2" | 3/4" | 1SM | 18 |
2-1/2" - 7-7/8" | 1-1/4" | 1 | 22 |
8" - 10" | 2-1/2" | 1LG | 22 |
![]() Style 1XSMFor pipes with O.D. of 3/4" to 1-1/4" (19 to 32mm) |
![]() Style 1SMFor pipes with O.D. of 1-1/2" to 2-3/8" (38 to 60mm) |
![]() Style 1For pipes with O.D. of 2-1/2" to 7-7/8" (64 to 150mm) |
![]() Style 1LGFor pipes with O.D. of 8" to 10" (200 to 250mm) |
Colors:
The secondary means of identification is the color code of the marker. The exact colors are contained in the ANSI Z535.1 Safety Color Code.
Color is the secondary means to identification but many times the most important. The color of the marker should be used to identify the characteristic hazard of the contents of the pipe. The following chart list the classifications shown by ANSI / ASME A13.1 2015 as the suggested color combinations for the pipe markers.

Installation Recommendations:
![]() Install pipe labels close to valves or flanges
|
![]() Install pipe labels near branches and whenever a pipe changes direction.
|
![]() Install pipe labels before and after all wall, floor and ceiling penetrations
|
![]() Install pipe labels at frequent intervals on straight pipe runs.

TAPE CALCULATOR CHART
When determining how much tape to order be aware of the following:
- Arrow Tape & Premium Banding Tape are 30 yard long while Economy Grade is 36yrd long.
- Most will apply tape on both ends of the pipe marker resulting in 2 bands per marker.
- Table Provides the quantities of bands for a specific O.D., not the quantity of markers.
- Be sure to include pipe insulation in size selection.
