What does the term "tap" refer to in the context of railway worker safety?

In the context of railway worker safety, the term "tap" refers specifically to the practice of notifying a worker of an approaching train without causing any harm. This method is critical for ensuring the safety of workers who may be in the vicinity of moving trains, as it allows for timely alerts while minimizing the risk of panic or distraction.

The practice of "tapping" serves as a crucial safety measure. It is often employed when visual signals or verbal communication are impractical due to noise or distance. By using a non-intrusive method, workers can be alerted to potential dangers in a controlled manner, helping to prevent accidents on the railway.

Understanding this terminology is essential for conducting safe railway operations, as effective communication plays a significant role in protecting workers. This knowledge enables workers to carry out their tasks with an awareness of their surroundings and to respond appropriately to impending hazards.
