The inside of the danger circle around the gun mounts should be approximately how many inches from the maximum rotating projection of the gun?

The correct answer is based on established safety protocols concerning the operating area around gun mounts on aircraft carriers. Specifically, the guideline specifies that there should be an approximate distance of 18 inches from the maximum rotating projection of the gun to the inside edge of the danger circle. This distance is crucial for ensuring that personnel are safely clear of potential hazards, such as moving parts and the associated risks of gun operations.

Maintaining this distance is a preventive measure to avoid accidents or injuries that could occur from the gun’s movement while it is being operated. This safety standard is particularly important in the confined spaces found on aircraft carriers, where ensuring adequate space around active equipment is vital for operational safety.
