Is it permissible to couple or move equipment that is protected by blue flag?

When equipment is protected by a blue flag, it is a critical safety measure that indicates that workers are present and that the equipment cannot be moved or coupled until the protection is removed. The blue flag serves as a visual warning and is a part of the safety protocols designed to protect employees working on or near rail equipment.

Permitting any movement of equipment under these circumstances creates a significant risk of injury or accident, as it compromises the safety of the workers who rely on those flags for their protection. Therefore, strict adherence to the prohibition against moving or coupling this equipment is essential to maintaining a safe workplace. This principle is foundational to ensuring the safety of all personnel involved in railroad operations. Any exceptions to this rule, including only allowing movement in emergencies, emphasize the critical importance of blue flag protection in preventing accidents and safeguarding lives.
