What does the acronym FDC stand for in firefighting?

The acronym FDC stands for Fire Department Connection. This term is crucial in firefighting operations as it refers to a portion of a building's fire protection system designed to allow firefighters to connect to a water supply, typically a pressurized water main or fire hydrant system. The FDC is often installed on the exterior of buildings and is used to supplement the existing fire protection sprinkler system, especially in large structures where the internal water supply may not be sufficient during a fire incident. It ensures that firefighters can quickly access additional water to combat fires effectively, thereby enhancing their ability to protect lives and property. Understanding this term is essential for firefighters, as it directly relates to operational efficiency and safety during fire suppression efforts.
