NFPA 2001 provides what about door fan test guidance and testing procedures?

• A. Results desired; test procedures are not specified
• B. Exact step-by-step procedures
• C. Only for water-based systems
• D. No guidance exists

Answer: (A)

NFPA 2001 uses a performance-based approach, focusing on what the door fan test needs to achieve rather than prescribing one exact method. It tells you the results you must demonstrate—such as that the protected space maintains the required agent concentration and that containment is achieved—while leaving the specific testing procedure to be determined by the situation and approved methods. This flexibility makes sense because enclosure sizes, door configurations, and system designs vary, so a single step-by-step procedure isn’t practical. Therefore, NFPA 2001 provides the results desired but does not specify exact procedures.
