What is the correct hose layout for the fire department connection (FDC) at a property with a sprinkler system?

• A. At least one 2-inch (50mm) hoseline
• B. At least two 2 1/2-inch (65mm) hoselines or one 3-inch (77 mm) hoseline
• C. Only one 3 1/2-inch (90mm) hoseline
• D. At least three 2-inch (50mm) hoselines

Answer: (B)

The correct hose layout for connecting to a fire department connection (FDC) at a property equipped with a sprinkler system is appropriately represented by the choice indicating either at least two 2 1/2-inch (65mm) hoselines or one 3-inch (77mm) hoseline.

This layout is essential to ensure that an adequate amount of water can be supplied to the sprinkler system in the event of a fire. The larger diameter hoselines allow for a higher volume of water flow, which is critical for effectively suppressing fire and supporting the sprinkler system's operations. The use of two hoselines also provides redundancy and can improve water flow if one line is compromised or if additional volume is necessary.

This particular configuration aligns with fire codes and best practices aimed at ensuring prompt and efficient firefighting operations, especially in commercial or larger residential properties where the demands for water may be greater compared to smaller or less complex structures. The choices that suggest using only smaller hoselines would not provide the necessary volume needed for such an application and might hinder effective firefighting efforts.
