Fire Hydrant Markers
Clearly label fire hydrants to show their flow rates, if they're out of service, or write your own message. Made of polyethylene plastic, these markers are durable enough that weather won’t dull their color. They’re also reflective, so they’re easy to see at night. All meet EN 12899-1:2007, a standard for sign durability and visibility.
To install, remove the hydrant cap, slide the marker on and replace the cap.
NFPA color-coded markers help you meet National Fire Protection Association standard 291, which gives guidance for color-coding fire hydrants by flow rates.
Write on blank markers to add a custom message.

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.

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.
