Which of the following best describes 'draftstopping'?

Draftstopping refers to the use of partitions or barriers specifically designed to prevent the movement of smoke and hot gases within a building during a fire. This is crucial for maintaining the integrity of fire-rated assemblies and protecting escape routes from smoke infiltration. By compartmentalizing space, draftstopping helps contain a fire to a specific area and delays the spread of smoke, allowing for safer evacuation and access for firefighters.

Understanding draftstopping is essential in fire safety, as it plays a significant role in the overall fire prevention strategy of a building. It is distinct from other functions; for example, while enhancing air quality relates to HVAC systems, draftstopping's focus is specifically on fire containment and smoke management.
