When handling a train service with equipment, what position ensures safety for the boom?

The trailing position is used to ensure safety for the boom when handling a train service with equipment. In this position, the boom remains behind the train during operation, which minimizes the risk of collision and allows for better visibility and control. This setup helps to avoid hazardous interactions with surrounding equipment and personnel, ensuring a safer working environment.

Furthermore, the trailing position allows the operator to maintain a safe distance from potential dangers that could arise from the train's movements or the surrounding area. Keeping the boom trailing also aids in maneuverability, providing more options for navigating the equipment without compromising safety. In scenarios where the boom might be elevated or horizontal, the risk of accidents or equipment damage increases, which is why the trailing position is preferred for safe operations.
