What is the primary purpose of setting condition zebra?

Setting condition zebra is primarily aimed at isolating and controlling fires and flooding on a vessel. This condition involves closing specific hatches, doors, and other openings to inhibit the spread of smoke, flames, and water, thereby protecting personnel and vital ship systems. By establishing this condition, the crew can limit the movement of fire and water, which are two critical threats in emergency situations, thus enhancing the overall safety and integrity of the ship.

In emergencies, various measures may be implemented to control the situation, but the focus of condition zebra is specifically on preventing hazards from escalating. This proactive approach allows damage control teams to work more effectively in addressing the threat, enabling them to stabilize conditions before potential rescue operations or full firefighting efforts. Therefore, the strategic intention behind condition zebra directly supports a vessel's damage control objectives.
