- Heat and Smoke Control Measures of Mechanical Ventilation System
The heat and smoke control measures of a mechanical ventilation system is a type of active fire safety system and smoke hazard management system in a building or structure and refers to the components and systems designed to manage and control the movement of heat and smoke during a fire by the mechanical ventilation systems within a building. These systems are designed in accordance with the performance requirements of the National Construction Code ("NCC") and Australian Standard AS 1668.1:2015.
These measures are integral to the building's fire safety strategy, aiming to improve visibility, reduce the spread of smoke and hot gases, and maintain tenable conditions for evacuation and firefighting.
Mechanical Smoke Extraction:
Systems that actively remove smoke from the building to maintain clear escape routes and reduce smoke inhalation risks.
Pressurization Systems:
Used to keep stairwells, corridors, and other escape routes free from smoke by maintaining higher air pressure in these areas.
Ducted Smoke Control Systems:
Utilize ductwork to channel smoke away from occupied spaces and towards designated exhaust points.
Emergency Ventilation Systems:
Provide additional airflow to dilute and remove heat and smoke, enhancing the effectiveness of smoke control measures.
