What should manual interlocking operators do during a close inspection in a hi-rail vehicle?

During a close inspection in a hi-rail vehicle, it is essential for manual interlocking operators to ensure that foul time is active. Foul time refers to the specific period during which tracks are considered to be occupied or not available for train movements, primarily to ensure safety during inspections or maintenance activities. By confirming that foul time is active, operators are preventing any potential for trains to inadvertently enter the area being inspected, thereby protecting personnel and equipment. This proactive measure is critical in maintaining operational safety and efficiency.

While it may seem important to coordinate with other operators, advise the train dispatcher, or postpone actions until the inspection is completed, these options do not specifically address the immediate safety protocol required during a close inspection. Ensuring that foul time is activated is the priority to protect both the inspection personnel and rail traffic management.
