Which scenario is an example of improper signaling?

The scenario of not repeating signals to confirm understanding exemplifies improper signaling because confirmation is a critical component of effective communication, especially in environments where clarity and safety are paramount. When signals are given, particularly in potentially hazardous settings like substations, it is essential to ensure that all parties involved understand the signals being communicated.

Failing to repeat or acknowledge signals can lead to misunderstandings or misinterpretations, which could result in accidents or operational failures. Proper procedures often include a confirmation step to reinforce understanding, ensuring that all individuals involved are on the same page. This practice minimizes the risk of mistakes that could arise from assumptions or unclear communication.

The other scenarios reflect appropriate signaling practices, such as using agreed-upon hand signals, giving signals from clear positions, and adjusting signals based on visibility. These practices promote safe and effective communication protocols, which are vital in maintaining operational integrity and safety in data transmission environments like substations.
