What is the area called between the inner and outer boundary in a firefighting context?

In firefighting terminology, the area between the inner and outer boundaries is referred to as the smoke control zone. This zone plays a crucial role in fire management, especially in situations where smoke can create hazards for personnel and hinder visibility. Effective smoke control is essential for ensuring the safety of both firefighters and civilians, as it helps to channel and manage the smoke produced during a fire.

The smoke control zone is designed to prevent the spread of smoke throughout a building or area, often utilizing physical barriers and ventilation strategies to keep the smoke contained within a designated region. This helps to maintain safer conditions for operations and evacuations.

Understanding the functions and implications of this zone is critical for planning and executing effective firefighting tactics, as smoke can significantly impede efforts and pose health risks.
