What is a fire department connection (FDC)?

A fire department connection (FDC) is an external point designed specifically for firefighters to connect hoses and supply additional water to a building's standpipes or sprinkler systems during a fire response. This allows fire crews to quickly boost the flow of water in situations where the building's internal water supply may be insufficient or compromised.

The FDC is typically located on the outside of a building, making it easily accessible for firefighters. The design ensures that first responders can connect their hoses rapidly, facilitating an efficient response to fire emergencies. By utilizing the FDC, firefighters can draw from external water sources, such as hydrants, to enhance the firefighting efforts effectively.

Understanding the function of the FDC is crucial in fire suppression training, as it underscores the importance of ensuring that these connections are maintained, accessible, and properly marked for quick identification during an emergency.
