About Selecting Pipe Markers

NFPA Diamond Labels
Add numbers, abbreviations, and symbols to indicate specific hazards and the degree of hazard using NFPA (National Fire Protection Association) labels. Write on them with a permanent marker or use adhesive-back characters (sold separately). They meet OSHA 29 CFR 1910.1200 safety color standards for indicating hazards.
NFPA Diamond Labels with Laminating Flap
Fill out these labels with codes that identify hazardous materials, then seal them with a clear plastic flap to protect the message. They have a National Fire Protection Association (NFPA) diamond that uses colors, numbers, and symbols to help you recognize hazards with a glance. Use a permanent marker to write the code that corresponds to your hazard on the diamond. To keep the message from rubbing off or washing away, fold the flap over the front.
Color Stripe Labels
The color stripes and reference chart identify the type of hazard. Write in the appropriate code numbers in the stripes and list required personal protective equipment using a permanent marker.
NFPA Diamond Labels with Reference Chart
A reference chart explains the NFPA (National Fire Protection Association) color and number designations for hazards. Provide the appropriate code number using the NFPA diamond. Write on these labels with a permanent marker or use adhesive-back characters (sold separately).
Hazardous Material Symbols
The graphics on these labels identify hazardous materials and provide safety reminders.
Personal Protective Equipment Symbols
The graphics on these labels identify areas that require personal protective equipment, such as safety goggles and boots.
Smoking Control Labels
Communicate smoking policies by sticking these labels on doors, windows, and equipment.
Labels that meet OSHA 29 CFR 1910.145 safety color standards indicate hazards that could harm workers.
Adhesive-Back Pipe Markers
Apply directly onto clean, dry pipes for clear identification of contents.
Style A have an alternating message. Wrap them around the pipe and you can read the contents whether the arrow points left or right.
Style B have a removable arrow; apply the message to a pipe and then turn the arrow to match your system’s flow direction. For a more secure hold, pair these with pipe marker tape—just layer the tape over the edge of your markers then wrap it around the full diameter of a pipe.
Pipe markers that meet ASME A13.1 adhere to requirements that, for a given pipe size, they have the proper minimum character height, identify contents with a message, indicate flow direction with an arrow, and designate hazardous classifications with a specific marker color. For messages with multiple marker color options, choose the color that best identifies the hazardous properties of the contents according to the ASME designations.
Pipe markers that meet CGA-9 standards adhere to strict requirements for color and message uniformity to identify gas lines and equipment in medical and pharmaceutical industries. When placed according to NFPA 99 standards, they also help you meet safety standards for medical gases in your facility.
