Safety Identification

We provide data collection for facilities to comply with OSHA and ANSI standards as well as 5s. This would include pipe markers, valve tags and signs. We work with the management and maintenance team to identify the piping and valves through blue prints and P&ID’s. If there aren’t any P&ID’s we can work with the team to create them for install and future use. These are also used in creating the database for valve tags. We evaluate the facility for proper signage and make our recommendations based on compliance with OSHA, aesthetics and uniformity. We use our standard OSHA compliant signage as well as design custom signage for the customers needs.

Pipe Marking Installation

NSI/ASME A13.1 is the pipe identification standard most commonly used in the United States. The standard specifies the primary and secondary means of identifying pipe contents, as well as the size, color and placement of the identification device.


The text legend (name of pipe content) and directional arrow remain the primary means of identifying pipe contents. Attaching arrows at one or both ends of the marker indicates flow direction. See the ANSI/ASME size chart and installation guide in the following sections for more details.


A secondary means of pipe marker identification is the color code of the marker. The terminology of inherently hazardous or nonhazardous has been removed from the standard, effective since 2007. The combination of Yellow/Black is now assigned to flammable fluids and oxidizing fluids while Green/White pipe markers identify potable, cooling, boiler feed and other water-related substances. These updates mean that legends such as hot water, cold water and steam will now use the color code of Green/White. Seton still offers many Yellow/Black pipe markers for these contents from many our top-selling brands as well.

Other significant color changes in 2007 included the addition of Brown/White for combustible fluids and Orange/Black for toxic or corrosive fluids. The fact that the standard has identified specific colors for flammable liquids, combustible fluids and toxic or corrosive fluids means Safety Data Sheets should be consulted before selecting a color. Further, if the pipe being labeled contains multiple hazards – like flammable and toxic – determining which poses the greater hazardous risk is vital and should dictate the way in which your pipe is marked. If chilled or heating systems contain toxic treatments, for example, the color combination should be Orange/Black.

The 2007 standard also identified four additional “defined by user” color combinations for additional customization options on non-standard markers. Those exact colors are the recommended safety colors contained in the ANSI Z535.1 standard.

The updates to ANSI/ASME A13.1 added oxidizing fluids to the definitions for Yellow/Black, but did not add any new colors to the standard.

We install signs that are designed or used often above halls and doorways to communicate or identify a message. It is displayed information that's presented in the form of words, symbols and/or pictures for safety prevention.

They are identification Labels valves that can be installed to prevent accidents and spills. They usually come in Brass, Aluminum, Stainless Steel, plastic or vinyl.
