∗ Pinch of salt ∗ 80g butter, chilled, cubed
∗ 185ml (3/4 cup) water
I’ve been asked to speak here today on the behalf of Airah to cover the maintenance requirements of fire and smoke dampers. The maintenance of Fire and Smoke dampers is documented in AS1851, Section 18. Within this standard it also touches on other applicable standards. AS3666.1 - 4 (Air-Handling and water systems of building – Microbial Control) AS1668.1 + 2 (The use of ventilation and air conditioning in buildings) AS1682.2 (Fire damper Installation) The following slides highlight the relevance of these standards.
Fire and Smoke Damper Maintenance
Fire and Smoke Damper Maintenance AS1668.1
The use of ventilation and air conditioning in buildings Part 1: Fire and smoke control in Multi compartment Buildings
This sets the standard for building ventilation in a fire mode, specifically: ∗ Air Handling Systems – General Requirements ∗ Air Purge Systems ∗ Zone Pressurization ∗ Fire/Smoke Damper positioning
It has been documented that smoke is a far bigger risk to life than fire in a building. ∗ Smoke obscures vision, preventing occupants
from finding safe escape routes. ∗ Smoke hinders the fire brigade in its search and
rescue operations. ∗ Smoke can kill by asphyxiation or by poisoning
people well before the temperature of the fire or smoke causes injury.
Fire and Smoke Damper Maintenance AS1668.2
The use of ventilation and air conditioning in buildings Part 2: Mechanical ventilation in buildings
This sets the standard for building ventilation requirements, specifically ∗ Minimum Outside air quantities ∗ General outside air quality ∗ Car Park exhaust requirements ∗ Kitchen exhaust requirements ∗ Specific air change requirements in medical facilities
It is very important these points are considered when maintaining dampers as shutting a damper on a system in operation could change any of the above to a point where it no longer complies with Australian Standards. For example areas of concern would be.. ∗ Hospital Theatres ∗ Clean Rooms ∗ Even outside air dampers in offices.
Fire and Smoke Damper Maintenance AS3666.2
Air-handling and water systems of buildings—Microbial control. Part 2: Operation and maintenance
This highlights the maintenance requirements of most aspects of a HVAC system where it may be affected by microbial issues, specifically: ∗ Outdoor air intakes and exhausts ∗ Coils, ducting, air filters & drains ∗ Evaporative air-cooling equipment ∗ Heated Water Systems ∗ Cooling Water Systems ∗ Operating And Maintenance Manuals And Maintenance Records “The air-handling system shall be inspected and maintained in accordance with AS 1851.” Ductwork and air-handling systems shall be serviced, unless otherwise specified, as indicated: for example. ∗ Coils and sumps Monthly ∗ Fans Quarterly ∗ Duct work Annually ∗ Air Outlet and return air grilles Annually
∗ Manufacturers installation requirements ∗ Fire resistance of surrounding
construction ∗ Mounting in a wall, floor or ceiling ∗ Airflow must not impede closure ∗ No temporary supports ∗ Attachment to ductwork ∗ Access for maintenance ∗ Clearance ∗ Positioning and controls ∗ Blade position ∗ Length of damper casing ∗ Packing

Fire and Smoke Damper Maintenance AS1851: Maintenance of fire protection systems and equipment
Section 18: Fire and Smoke control Features of HVAC Systems
∗ Can you get access to the fire damper in order to inspect it? ∗ Is the fire damper still there, has the position changed? ∗ Has the mechanism corroded making the damper ineffective? ∗ Will the blades close freely when released and latch effectively? ∗ Will dust, lint or corrosion on the blades and linkages prevent operation, or has
dust/lint clogged the free area of an intumescent fire damper? ∗ Is the casing still capable of retaining the fire damper in the fire resistant wall or
guiding the damper closed? ∗ Has it been corroded or dislodged from its proper position?
Fire and Smoke Damper Maintenance
AS1851 Fire Damper Maintenance Checks
Consideration must be made if recent renovations or modification have been made.
∗ Is the damper still effectively in the
wall? ∗ Are there any breaches of the walls
integrity around the fire damper? ∗ Has recent tenancy work adversely
affected the fire damper?
