How does a partial evacuation differ from a full evacuation?

• A. Partial uses only selected exits; full uses all available exits; implemented as directed by the captain and crew on scene
• B. Partial uses all exits; full uses one exit
• C. Partial evacuates only crew
• D. Partial is optional

Answer: (A)

Evacuation strategy depends on what exits can be used safely. A partial evacuation uses only selected exits—doors that can be opened and slides that can deploy safely—while directing passengers to those specific exits. A full evacuation, by contrast, employs all available exits and slides to move everyone out as quickly as possible. The captain and crew on scene determine which exits to use based on conditions like fire, smoke, or debris, and they coordinate the passage of passengers to those exits.

Other options misstate the concept: one suggests the opposite use of exits, another implies only crew evacuate, and another treats partial evacuation as optional—none reflect how the crew directs egress based on safety assessments and available exits.
