What is a key concern when working around transponders?

The primary concern when working around transponders is the potential for damaging these units, which could lead to system interruptions. Transponders play a crucial role in railway operations, as they are responsible for communication between trains and control systems. Damage to these units can disrupt signaling and coordination, resulting in delays, increased safety risks, or even accidents. Therefore, ensuring the integrity and functionality of transponders is essential for maintaining safe railroad operations.

While other factors, such as weather conditions or proximity to train tracks, may also be relevant in a broader context of roadway worker protection, the direct impact of damaging the transponders makes it a more immediate concern in this scenario. Special uniforms, although important for safety, are not specifically related to the operational functionality of transponders.
