How does NFPA 13E treat temporary shutdowns or isolation of hydrants?

• A. There are no procedures for shutdowns.
• B. Procedures should be in place to safely isolate sections while maintaining overall readiness and safety.
• C. Hydrants must be permanently shut down during maintenance.
• D. Shutdowns require immediate replacement of hydrants.

Answer: (D)

Temporary shutdowns are managed with documented procedures that allow safe isolation of the affected hydrant sections while keeping the rest of the system ready to operate. NFPA 13E expects that maintenance or testing can occur without compromising overall fire protection, so the plan should specify how valves are isolated, how water supplies are maintained for remaining hydrants, and how coordination with the fire department and building staff is handled. This approach keeps protection intact and avoids leaving the system unprotected or abruptly removing hydrants. Permanent shutdowns or immediate replacement during every shutdown aren’t the intended approach; the focus is on safe, controlled isolation that preserves readiness and safety.
