What are secondary boundaries used for in a flooding scenario?

In a flooding scenario, secondary boundaries serve multiple critical functions aimed at mitigating the impact of the incident. One key purpose is to check the spread of smoke and contain it to a designated area, which is particularly important in managing visibility and ensuring breathable air for personnel performing damage control and rescue operations. By effectively controlling smoke, secondary boundaries help maintain a safer environment in adjacent compartments.

Additionally, these boundaries create a safe area for personnel, allowing them to work effectively without being directly exposed to water or hazardous conditions originating from the flooding. This is crucial for maintaining operational effectiveness and ensuring the safety of the crew while they are engaged in damage control efforts.

In summary, secondary boundaries are vital not only for isolating the flooding source but also for controlling the environment, such as smoke, and creating safe working conditions for personnel. All these factors significantly enhance the effectiveness of emergency response during a flooding event, making them an indispensable part of damage control procedures.
