What occurs when the circle yoke condition is set?

The correct answer is that fittings may be opened without permission but must be closed immediately when the circle yoke condition is set.

The circle yoke condition is a specific state in damage control management indicating a temporary situation where a ready condition is needed due to the threat of flooding or fire. Under this condition, certain fittings or closures can be accessed without formal permission, allowing for quick action to prevent or mitigate potential damage. The key requirement, however, is that once the immediate need is addressed, those fittings must be closed right away to maintain control and protection of the area from potential hazards.

This flexibility is critical for maintaining operational readiness during emergencies while still ensuring safety and compliance with damage control protocols once the situation is under control.
