What must be done with external fire hoses during cold weather conditions?

In cold weather conditions, it is essential to prevent fire hoses from freezing, which can render them unusable in case they are needed for an emergency. Stowing them inside the skin of the ship helps to protect them from the elements, including freezing temperatures, thus ensuring that they remain functional. Keeping the hoses inside also allows for easier access in an emergency without the risk of them being encumbered by ice or snow.

While ensuring operational readiness and properly maintaining equipment is critical, simply leaving hoses in place for emergencies or ensuring they are operational without proper storage can lead to issues during freezing conditions. Additionally, draining hoses and storing them outside can expose them to further risk and defeat the very purpose of having them ready for use. Therefore, storing the hoses inside the skin of the ship is the most effective measure for protecting them during cold weather conditions.
