If agent containers are stored in a dedicated space on a marine vessel, doors at exits shall swing outward.

• A. They shall swing inward
• B. They may swing either direction
• C. They are not specified
• D. They shall swing outward

Answer: (D)

Exits must be arranged to allow rapid, unobstructed egress in an emergency. When agent containers are stored in a dedicated space on a marine vessel, that area is a high-hazard egress scenario requiring doors at exits to swing outward. This direction means the door opens toward the escape route, so people exiting push the door into the corridor rather than pulling or pushing against a door that swings into the room. In narrow shipboard spaces with potential smoke or heat, outward-swing doors reduce the risk of the door becoming blocked by occupants, equipment near the threshold, or by a crowded flow, helping maintain a clear path to safety. If the door swung inward, it could be blocked by those evacuating or require more force to move, slowing egress. Allowing either direction or not specifying would not ensure the safety benefit in this context. So the required arrangement is that doors at exits swing outward.
