To enhance safety, what is typically done to doors and hatches on intentionally sunk vessels?

In the context of intentionally sunk vessels, doors and hatches are typically removed to enhance safety. This practice eliminates potential entrapment hazards for divers exploring the wreck. Open access prevents divers from being trapped inside enclosed areas, which could pose serious risks in case of strong currents or changes in visibility. Removing doors and hatches ensures that divers can navigate the wreck safely and reduces the chance of being caught in a confined space.

While painting bright colors could potentially increase visibility, securing doors with bolts or leaving them open does not fundamentally address the issue of entrapment. Instead, removing them entirely creates a safer environment for those exploring the wreck. This approach is part of carefully planned and executed wreck diving practices that prioritize diver safety while allowing for exploration.
