Of all the components that make up a fire-protection system, fire dampers are the most difficult to locate, especially if the damper has limited access and no documentation of location has been kept. Located within HVAC system ductwork, these dampers prevent the spread of fire and smoke to other compartments of the building throughout the HVAC system. Australian Standards 1851-2005 requires building owners to Inspect 20% of the fire dampers annually so that all dampers have been inspected by the end of the fifth year. Flowtest Balancing and Commissioning can implement service agreements to our clients future budgets, dividing fire inspections over a period of 5 years. Which is 20% per year as per Australian standard.
