Which document is commonly included in the NFPA 2001 commissioning package?

• A. Vendor invoices
• B. Marketing brochures
• C. System drawings
• D. Employee handbooks

Answer: (C)

The essential thing being tested is documentation that shows exactly how the system is laid out and connected. System drawings provide the precise layout of piping, nozzles, detectors, release devices, and control connections, so you can verify in the field that the installation matches the design and plan the commissioning tests accordingly. These drawings serve as the reference during acceptance testing, help confirm zones and coverage, and support future maintenance or modifications.

Vendor invoices, marketing brochures, and employee handbooks don’t depict the installed system or its configuration, so they aren’t part of the commissioning package.
