Why it is the ships responsibility to cover or fence hatches when stevedores knockoff?

It is the ship's responsibility to cover or fence hatches when stevedores finish their work to ensure safety and prevent accidents. Uncovered hatches pose a significant risk of falls or injuries, particularly if personnel are still moving around the area. Additionally, securing these openings helps protect cargo from potential damage or contamination. By taking this precaution, the ship maintains a safe working environment and fulfills its duty of care to all personnel involved.
