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