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, which means they won't release more than trace amounts of hazardous chemicals and won't pose a physical hazard or health risk to employees.
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.

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.
