What action is indicated for any new crack?

• A. Closure
• B. Return to service
• C. Document and monitor
• D. Ignore

Answer: (A)

New cracks signal potential loss of structural integrity, and loading could cause them to propagate. The safest course is to close the structure or restrict its use until a qualified engineer can evaluate the crack—its size, location, orientation, and cause—and decide on repairs or mitigation. Closing prevents further deterioration and protects public safety, which is why closure is the indicated action. Merely documenting and monitoring delays necessary action and could allow unsafe conditions to persist; returning to service without an evaluation or ignoring the crack would be unsafe.
