23 11.4 Design and Installation survey A survey is typically conducted visually from floor level and is intended to identify changes to fire extinguishers, or the building and its environment that could impair the performance of fire extinguishers Cylinder Lining Where a cylinder lining is found to be suspect as to its soundness, e.g., the lining shows evidence of cracking, separation from the wall of the cylinder, lifting of the lining, or any signs of bubbles or irregularities in the lining, the cylinder shall be condemned Water Quality In areas where the water supply, whilst of drinking quality (potable) may be unsatisfactory for prolonged contact under pressure with water-type fire extinguisher cylinders, either specially treated cylinders shall be used, or a corrosion inhibitor shall be added to each charge in the extinguisher. Extinguishers used in these areas shall be supplied with the appropriate treatment in accordance with the extinguisher manufacturer s recommendations If in any doubt as to the water quality, an inhibitor shall be added as failure to do so may result in rapid deterioration of the extinguisher, leading to leakage or failure to operate Maintenance shall be undertaken with greater regularity where: 11.7 Corrosion (a) Water quality has proved to be a problem, or is likely to be a problem; (b) Salts are deposited in extinguishers; or (c) Hard water is used Where an extinguisher is pitted or otherwise damaged by corrosion and it cannot be determined if the damage is within the limits detailed in AS , then the cylinder shall be condemned Exceptions Fire extinguishers designed for one-off use, such as aerosol and nonrechargeable types, shall undergo all inspection and test requirements contained in Section except for those requiring the depressurizing of the cylinder, removal of the operating head, inspection of the contents, and inspection of the interior of the extinguisher Pressure Test Marking Extinguishers (with the exception of carbon dioxide types) that have passed the hydrostatic pressure test shall have the month and year of the test clearly and permanently marked on the skirt or neck ring of the cylinder.

29 (e) (f) (g) (h) (i) Fire shutters Fire-rated glazing Access panels and ceiling hatches Ducts and dampers Fire stopping elements: Service penetrations and control joints (metal/plastic pipes, electrical cables/conduits/cable tray, construction/control joints and deflection heads) 12.2 Application General Passive elements of fire and smoke containment systems (passive protection) are illustrated in Figure 2 and Figure 3, and form the basis of the maintenance program Compartment Integrity The basis of maintenance for compartment integrity is to identify the respective vertical and horizontal barriers and their respective fireresistance level (FRL) or smoke containment requirements and to ensure all openings or service penetrations and control joints in these barriers do not compromise the performance requirements relating to fire and smoke compartmentation Structural Fire Resistant elements The basis of maintenance for structural fire-resistance elements is to identify all the structural elements (beams, columns, girders and trusses), and their respective fire-resistance level (FRL) requirements and to ensure adequate fire protection coverings are incorporated at the correct thickness and that they are in good condition.

32 12.4 Design and Installation Survey General A survey of all fire and smoke containment elements shall be conducted using existing compartmentation integrity, structural integrity or appropriately marked general drawings and any associated schedules, which show the location of all the items and the requirements for fire and smoke containment Suitable documentation is to be produced and made available for the survey Compartmentation Integrity A survey shall be conducted visually using the compartmentation integrity drawings or appropriately marked general drawings and any associated schedules to identify or locate all relevant passive fire and smoke containment systems, and to determine whether there are any new barriers and/or penetrations added or removed, and if any of these may potentially impair the overall performance of the building in terms of fire and smoke containment Structural fire integrity A survey shall be conducted visually, using the structural fire integrity drawings or appropriately marked general drawings and any associated schedules, to identify or locate all structural elements and associated FRL requirements and to determine whether there are any areas where there may potentially be a requirement to add a fire protective covering or to repair an existing fire protective covering Marking, Labelling, Tagging and Signage Fire Doors Passive fire and smoke containment systems shall be labelled for identification purposes. a) Fire doorsets are required by AS to be tagged. b) Smoke doors and solid core doors, as required by the BCA or by specific designs, should be tagged or labelled in a similar manner to that of fire doors. c) The labels may be numbered to coincide with the key used on any compartmentation integrity or appropriately marked up general drawings and any associated schedules Compartment Barriers and Penetrations A service label, similar to Figure 4 shall be affixed adjacent to each service penetration or control joint and shall contain, as a minimum, the information specified in MCSS PRINTOUT MAY NOT BE UP-TO-DATE; REFER TO METRO INTRANET FOR THE LATEST VERSION Page 32 of 46

34 13.2 Application This Section only applies to the fire and smoke control features of HVAC systems, including the shutdown function for systems that are required not to run in fire mode Where operation of HVAC systems in fire mode is not specified by Standards or building codes, this Standard does not apply (see Table 5). Table 5 Application of AS 1851 to HVAC Systems HVAC System Required Fire Mode Operation Application of AS 1851 Exit Pressurisation Run Yes Smoke Control Run Yes Smoke Exhaust (Note 1) Run Yes Air-handling Run Shutdown Optional Yes Refer Note 2 below N/A Note 1: Smoke exhaust systems, smoke control systems and exit pressurization systems are required to be tested at least annually to demonstrate they are capable of performing to the Standard to which they were installed. In the case of the following systems, this requires measurement of parameters required by AS/NZS or the relevant building codes. For example: (a) Pressurization systems Doorway velocities, door opening forces, restoration times, etc. (b) Smoke control systems Differential pressures, etc. (c) Smoke exhaust systems Airflow rates Note 2: Some buildings may have stand-by power generation provisions that are required to operate fire and smoke control equipment and controls in the event of a normal power failure. Partial Simulation tests and Full Simulation tests should be carried out under stand-by power to verify fire mode performance. Where a system has more than one fire or smoke zone, verification of fire mode operation of the stand-by power need only be carried out for one zone, the most critical in terms of power consumption.
