Which color on Fire Hydrant Service rings indicates the hydrant is Out of service?

• A. Blue - In use
• B. Orange - Out of service
• C. White - FD Use
• D. Green - Construction

Answer: (B)

Hydrant service rings use color as a quick status indicator for responders. When the ring shows orange, it means the hydrant is out of service and should not be used until it’s marked available again. This helps prevent attempting to draw water from a hydrant that isn’t functioning or is undergoing maintenance, ensuring crews rely on hydrants that are ready for operation.

For context, other colors carry different meanings: blue indicates the hydrant is currently in use, white means the hydrant is for fire department use, and green indicates construction-related restrictions. While color codes can vary by location, in this scenario orange specifically denotes out of service.
