In order to use compartmentation to its fullest
advantage and to provide maximum preparedness, all the
doors, hatches scuttles access valve and fittings of
damage control valves were given a classification. The
classifications were based on the ships current status.
The least protective classification was reserved for in
port a safe harbor or port. The highest level for
imminent possibility of attack. At the highest levels of
protection each space was made a water and fire tight as
possible often stopping all air flow making the inside
temperature of the ship extremely high particularly when
operating in the tropics or south pacific ocean. |
