What kind of clearance is required around a NFPA 20 fire pump?

• A. Insufficient clearance is allowed if space is tight.
• B. Clearance is not specified by NFPA 20.
• C. Clearance must be at least 2 feet, but more is preferred.
• D. Sufficient clearance for maintenance, inspection, and operation per manufacturer and AHJ requirements.

Answer: (D)

Clearance around a NFPA 20 fire pump is about providing enough space for maintenance, inspection, and operation, and the exact amount is set by the pump manufacturer’s installation instructions and the Authority Having Jurisdiction (AHJ). NFPA 20 emphasizes accessibility and serviceability, so the area must allow disassembly and service of the pump, driver (motor or engine), priming equipment, and associated piping, as well as safe testing and routine inspections. If space is limited, you still must follow the manufacturer’s minimum clearances and any AHJ requirements. That’s why the best choice is to specify sufficient clearance per manufacturer and AHJ requirements.
