What is a Fire Damper?
Fire dampers are crucial components in the realm of passive fire protection. They prevent the spread of fire and smoke within buildings, primarily through HVAC duct work, but also in walls and floors. These devices automatically close when they experience heat or smoke. Thus they effectively contain the fire and buy valuable time for evacuation.
Types of Fire Damper
- Fusible Link Dampers: These use a bimetallic strip that melts at a predetermined temperature, causing the damper to close and block airflow.
- Intumescent Dampers: Made from materials that expand when heated, these dampers seal off the duct work to prevent fire spread.
- Motorised Smoke Dampers: Controlled by motors, these dampers activate by heat detectors, smoke detectors, or manual controls.
Inspection and Testing
Routine inspection and testing of fire dampers is mandatiory in the Australian Standard AS1851 – 2012. This standard requires that 20% of fire dampers undergo inspection and testing annually. A a result ensuring all dampers are checked within a five-year period. If there is a high failure rates during inspections then that points to a comprehensive check of all dampers within the next 12 months. This is necessary to address potential systemic issues.
Specialist Area of Fire Protection
Fire dampers fall under the specialist area of passive fire protection. This is an area which is technical and complex. Proper installation and maintenance require a deep understanding of HVAC systems and the Building Code of Australia (BCA). Often, fire protection contractors may refer to or engage passive fire specialists to diagnose and rectify issues.
Fire dampers are vital for maintaining building safety by preventing the spread of fire and smoke. Regular inspection and adherence to standards like AS1851 ensure these devices function correctly, providing critical protection in the event of a fire.
