How does NFPA 13E view temporary system modifications during maintenance?

• A. Temporary modifications are not allowed.
• B. Temporary modifications should be documented after maintenance.
• C. Temporary modifications should not compromise protection, must be documented, and restored after maintenance.
• D. Temporary modifications do not require documentation.

Answer: (C)

Temporary modifications during maintenance must not reduce the level of protection provided by the system. They should be documented, detailing what was changed, who approved it, and the expected duration, and the system must be restored to its normal configuration after maintenance is complete. This approach keeps protection continuous, provides a clear record for future inspections, and prevents leaving the system in a degraded or unfamiliar state. If work requires altering a component or creating a temporary bypass, the change should be limited in scope, its impact assessed, and restoration verified before normal operation resumes.
