When entering submerged fuselage compartments, divers should enter from where?

Entering submerged fuselage compartments, divers should do so from the deepest point accessible. This approach is crucial because it allows divers to mitigate the risks posed by potential entrapments and ensures a more efficient escape route in case of an emergency. By starting at the lowest point, divers can ascend safely, gaining access to any trapped air pockets that may exist above them, which may aid in maintaining buoyancy and providing a vital air supply should they encounter difficulty.

This method also helps divers avoid the complications of debris or structural hazards that might be present at higher points in the fuselage. Thus, entering from the deepest point significantly enhances safety and effectiveness during rescue operations in submerged scenarios.
