What must be established at the work location before any worker fouls a track?

Before any worker fouls a track, it is essential to establish the on-track safety protection. This safety measure ensures that workers are adequately protected from potential hazards associated with the operations on or near the tracks. Establishing on-track safety protection includes implementing protocols and systems such as flagging, safe work zones, or use of specialized equipment to prevent accidents and ensure the safety of all personnel involved in the operation.

While other options like an emergency exit procedure, communication plan, and timeline for the project are important aspects of planning and operations, they do not provide the necessary immediate safety protection required for workers who are near or working on the tracks. The primary focus in such scenarios is the implementation of safety measures that directly prevent accidents, making the establishment of on-track safety protection the most critical step prior to any worker entering the hazardous area of a fouled track.
