Under what condition can ITD be used to establish On-Track Safety?

The option indicating that all conditions must be met for using ITD (Interim Track De-energization) to establish On-Track Safety is correct because it reinforces the importance of a comprehensive approach to ensure safety in rail operations. Utilizing ITD requires a thorough assessment of the environment which includes securing the area with barriers to prevent unauthorized access, ensuring there are no approaching trains that could pose an immediate danger, and confirming that the worker is familiar with the track to mitigate risks associated with working in proximity to railroad operations.

Securing the area with barriers is crucial as it helps prevent accidental entry into dangerous zones. Knowing that there are no approaching trains is vital to protect workers from potential collisions or accidents while on the track. Familiarity with the track allows workers to operate safely based on their understanding of its characteristics and any relevant procedures for the specific location. All these measures contribute to creating a safe working environment, hence necessitating that all conditions are beneficial to the establishment of On-Track Safety using ITD.
