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.

Tags are laminated in plastic so they hold up outdoors. Use them to communicate dangers to workers near equipment that could cause injury. Write on them using a permanent marker. All tags meet OSHA safety color standards for indicating hazards. Attach them with an included cable tie.

Danger headers are typically used in extreme conditions to indicate an imminently hazardous situation that, if not avoided, will result in death or serious injury.
