A standardized system categorizes fireplace hydrants by their accessible water move fee, indicated by the colour of the hydrant’s bonnet and, often, the physique. This classification permits firefighters to rapidly assess a hydrant’s capability, essential for efficient fireplace suppression. As an example, a light-weight blue bonnet sometimes signifies a move fee of 1500 gallons per minute or better.
Speedy identification of water availability is paramount in emergency conditions. This technique reduces response instances by eliminating the necessity for firefighters to check every hydrant individually. Traditionally, inconsistencies in hydrant design and signage hampered firefighting efforts. Standardized color-coding gives a common visible language, bettering interoperability between completely different fireplace departments and jurisdictions.
