What is the primary reason for proper segregation and quarantine of nonconforming materials?

• A. To prevent use in construction and to allow proper disposition per contract.
• B. To speed up production.
• C. To reduce documentation.
• D. To mix with conforming materials for testing.

Answer: (A)

Segregation and quarantine are used to keep materials that don’t meet specs from being used in the project. The primary reason is to prevent nonconforming materials from entering construction and to allow proper disposition per contract. By isolating them, the team can document the deviation, determine the cause, and decide the appropriate action—return to supplier, repair or rework, scrap, or other contract-approved disposition—without contaminating conforming materials. This protects safety, performance, and cost, and ensures clear traceability and accountability in the quality control process, following the contract’s requirements for acceptance or rejection.
