What must be in place if the ground equipment is at the aircraft?

The Diamond of Safety is essential when ground equipment is at the aircraft because it is a visual and physical indicator that enhances safety on the ramp. The Diamond of Safety is typically a defined area around the aircraft where specific safety protocols must be observed. This designation helps to ensure that all personnel and equipment are aware of the presence of ground equipment and the potential hazards associated with working in close proximity to the aircraft.

The placement of the Diamond of Safety promotes situational awareness among ground crew members and prevents accidents or injuries by clearly marking the area that requires caution and attention. It establishes a safe operating perimeter, ensuring that everyone involved in ramp operations can perform their duties while minimizing risks associated with ground equipment being in the vicinity of an aircraft.

Other measures like Safety Cones, the Safety Net, or Ground Equipment Markers may contribute to safety but do not have the same specific function of denoting the operational risks and safety boundaries that the Diamond of Safety provides. Thus, it is critical that the Diamond of Safety is implemented when ground equipment is present.
