What is not considered when going between cars or locomotives according to safety protocols?

When considering safety protocols for going between cars or locomotives, the operation of the uncoupling lever is not factored in as a specific safety concern. The other elements listed, such as placing the body in harm's way and waiting for slack to adjust, are critical safety issues. Placing oneself in a position where one can be hit or injured is a major danger, thus protocols emphasize avoiding such situations. Additionally, waiting for slack to adjust ensures that the movement between cars or locomotives is safe, as slack can lead to sudden movement that can cause injury.

Ensuring that the work is understood by the entire crew is also essential, as miscommunication can lead to dangerous situations. The operation of the uncoupling lever itself is a procedural action that, while it must be performed correctly, does not pose a specific physical safety risk when the individual is moving between cars or locomotives, distinguishing it from the other considerations that directly relate to personal safety in that context.
