What must the installing company do with the second copy of the contractor's material and test certificate?

• A. Retain it at its place of business in a separate file used exclusively for that purpose.
• B. Deliver it to the building official
• C. Return it to the supplier
• D. Destroy after inspection

Answer: (A)

Keeping the second copy at the installing company’s place of business in a separate file ensures a permanent, accessible record of the materials and tests for future reference, inspections, or audits. This documentation traceability helps verify what was installed and tested and supports timely compliance checks. The other copies are typically used for the building official or returned to the supplier, and destroying or not retaining the second copy would remove this important record.
