When a compartment begins to flood, what is the immediate action for the DC team?

• A. Open all hatches to vent air.
• B. Isolate the space by closing hatches, doors, and valves to stop the water source.
• C. Move crew out of the space without stopping water.
• D. Shutdown the power to pumps elsewhere.

Answer: (B)

When flooding starts, the immediate action is to isolate the space by closing hatches, doors, and valves to stop the water source. This quickly stops new water from entering the compartment, containing the flood and reducing the risk to adjacent spaces and equipment. Once the space is isolated, the team can deploy dewatering measures and assess any remaining hazards. Opening all hatches to vent air isn’t effective because it doesn’t stop the water and can allow floodwaters to move more freely between spaces. Moving crew out without stopping the water leaves the space vulnerable to ongoing flooding. Shutting down power to pumps elsewhere isn’t the first step because you still need the opportunity to remove water after isolation; cutting pump power can hinder rapid dewatering.
