Which of the following is a requirement for fire department connections (FDC) according to NFPA 13, 2017 edition?

The requirement for fire department connections (FDC) to be installed in a location easily accessible to fire apparatus is essential for ensuring that responding firefighters can quickly and efficiently connect their hoses to supply water to a building's sprinkler system during a fire emergency. The accessibility of the FDC allows for rapid deployment, which is critical for minimizing fire damage and protecting lives.

This requirement underscores the need for comprehensive planning in the design and location of fire protection systems, ensuring that those who are responding to an emergency can efficiently use the existing infrastructure without unnecessary delays. Accessibility is not just about convenience; it is about effectively managing a life-threatening situation where every second counts.

While other considerations, such as marking the FDC with red paint or ensuring it is not obstructed, are also important for visibility and functionality, their primary concern is secondary to the fundamental need for easy access by fire personnel. Ensuring the FDC is positioned in a way that allows immediate access by fire trucks and crews directly addresses the operational efficiency needed during an emergency response.
