For how long must the contractor's material and test certificates be retained?

• A. For one year
• B. For the life of the system
• C. For five years
• D. Indefinitely

Answer: (B)

Documentation about the materials used and how they were tested must be kept for the life of the sprinkler system. Keeping these certificates for the system’s entire life ensures you have verifiable proof of compliance and testing whenever inspections, maintenance, repairs, or future modifications occur. If the records are kept only for a short period, they may not be available when needed as the system ages. Indefinite retention isn’t the standard requirement for this specific item, so the lifetime of the system is the most appropriate duration.
