NFPA Standard Explorer

Standpipe and hose system installation standard. Useful for understanding expected standpipe performance, system layouts, and operational considerations in mid/high-rise environments (high level).

Standpipes are the building’s interior water supply plan. If crews assume performance that isn’t there—or connect incorrectly—attack lines can be delayed or ineffective where time and access are already challenging.

• Standpipe system types and installation intent (high level)
• Outlet/valve arrangement concepts (high level)
• Water supply and pressure performance intent (conceptual)
• Acceptance/verification concept areas (high level)
• Coordination with pumps, sprinklers, and fire department connections (high level)
• Documentation and system identification concepts (high level)

• High-rise preplans: locating FDCs, risers, outlets, and control valves
• Training on standpipe hookups and pressure management basics
• Plan review support and field inspection checklists
• Post-incident evaluation: diagnosing standpipe performance issues

• All standpipes deliver the same pressure/flow (system type and supply matters).
• FDC connection solves everything (supply and configuration still matter).
• Standpipe operations are ‘specialty’ (they’re core in many districts).

• In preplans: record FDC location, outlet locations, and stairwell identifiers
• Train a repeatable hook-up sequence and communications plan
• Coordinate with building management for access/keys and valve locations
• Document known low-pressure issues and backup water supply options
