Multiple Choice

A control valve secured with a lock is permitted to be inspected how often?

Explanation:
Regular checks of a control valve with a lock focus on verifying that the lock and tag are in place, the lock is intact, the valve remains in the intended locked position, and there are no signs of tampering or mechanical issues. Inspecting monthly provides a practical balance: it catches problems early—such as a missing or damaged lock, tampering, corrosion, or the valve drifting from its locked position—without imposing the overhead of more frequent checks. Weekly checks are generally more than needed for this item, while quarterly or annual inspections risk missing developing issues that could affect system readiness. So, monthly is the appropriate interval.
