During salvage operations, what must be avoided to ensure safety when the LCAC is clear of obstruction?

The correct response focuses on the importance of safety procedures during salvage operations, particularly in preventing accidents that can occur from running over equipment or personnel. Running over the tow bridle poses a significant risk because it can lead to severe damage to both the landing craft air cushion (LCAC) and the tow equipment, potentially creating hazardous situations for crew members and impacting the efficiency of the operation.

In the context of salvage operations, ensuring that all equipment is clear and that personnel are at a safe distance from moving craft is crucial. Running over the tow bridle could disrupt the towing system, leading to unexpected movements or disconnections, which compromises the safety of all involved.

Other considerations in the options provided may pose risks as well, such as the potential dangers associated with dragging equipment or operating in restricted areas, but specifically avoiding the act of running over the tow bridle directly relates to maintaining a safe operational environment and mitigating risks associated with physical obstacles.
