A standardized system categorizes hearth hydrants by their accessible water circulate 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 hearth suppression. As an illustration, a light-weight blue bonnet sometimes signifies a circulate charge of 1500 gallons per minute or higher.
Fast identification of water availability is paramount in emergency conditions. This technique 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 totally different hearth departments and jurisdictions.
