The hydraulic design information sign provides which of the following?

• A. Building occupancy data
• B. Fire department contact numbers
• C. System commissioning procedures
• D. Additional informational references related to the content of the standard

Answer: (D)

The main idea here is that the hydraulic design information sign is meant to point you to the standard’s guidance that supports the system’s design data. In NFPA 14, this sign acts as a quick reference for the hydraulic design data used for the standpipe or hose system, including where to find the calculations, design criteria, and related requirements within the standard. It’s not a place to list occupancy data or emergency contact numbers, nor is it a sign for commissioning procedures. Instead, it provides additional informational references related to the content of the standard so anyone reviewing the system can locate the exact NFPA sections that verify the hydraulic design. The other options don’t fit because occupancy data and contact numbers belong on separate project or site documents, and commissioning procedures belong with the testing/commissioning documentation rather than the hydraulic design information sign.
