11.3 Aggressive Environment 11.3.1 Unless protected from the effects of an aggressive environment (see Section

8.2.4), extinguishers located in such environments shall be subject to a more comprehensive maintenance program by conducting the five-yearly inspection, test and preventive maintenance schedules, every three years.






11.4 Design and Installation survey 11.4.1 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.

11.5 Cylinder Lining 11.5.1 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.

11.6 Water Quality 11.6.1 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.

11.6.2 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.

11.6.3 Maintenance shall be undertaken with greater regularity where:

(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.

11.7 Corrosion 11.7.1 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 2337.1, then the cylinder shall be condemned.

11.8 Exceptions 11.8.1 Fire extinguishers designed for ‘one-off’ use, such as aerosol and non-

rechargeable types, shall undergo all inspection and test requirements contained in Section 11.19 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.

11.9 Pressure Test Marking 11.9.1 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.






11.10 Service Labels 11.10.1 Any service label applied to the extinguisher after servicing shall not exceed 90

mm × 50 mm in size and shall not be applied on the coloured identification band, over any manufacturers’ labels or instructions, or on the maintenance record tag or label.

11.11 Defects 11.11.1 Defects, including faulty or defective components advised by public notices or

manufacturers’ service bulletins, shall be replaced, exchanged or repaired.

11.11.2 Defects that can be repaired on site shall be repaired immediately, or reported, or reported to the owner / occupier or agent. Any unit that is not repaired shall have a red “out of service” tag attached and evidence of compliance shall not be applied to the maintenance record tag or label.

11.11.3 Defective extinguishers that can not be repaired on site shall be removed from site for repair, or reported to the owner. Any defective unit that is not removed for repair shall have a red ‘out of service’ tag attached and evidence of maintenance shall not be applied to the maintenance service tag or label.

11.11.4 A replacement unit of the same type and size or similar rating shall be left in place of the unit removed from site.

11.11.5 To prevent the ‘out of service’ tag being removed from the extinguisher, it shall have a tear-off section identifying the extinguisher, its location and the fault shall be signed by the buildings owner, occupier or agent.

11.11.6 Extinguishers with defects that cannot be repaired shall be condemned, and tagged or labelled as appropriate. The label shall have black letters, not less than 10mm high, on a yellow background.

CONDEMNED – DO NOT USE.

11.11.7 Evidence of the maintenance level shall not be applied to the maintenance service tag or label. A record of the inspection and the outcome shall be made in the maintenance records.

11.11.8 Unsuitable equipment shall be returned to the owner with a ‘defective component’ report and an ‘action required’ report.

11.11.9 Actions taken shall be recorded in the maintenance record.

11.12 Recharging Agent 11.12.1 Recommendations and instructions for the recharging of fire extinguishers are

included on the extinguisher label supplied by the manufacturer. These instructions include the quantity and type of extinguishing agent to be used.

11.12.2 Where an internal inspection of the extinguisher and its components is required, but a discharge test is not specified, the extinguishing agent (with the exception of vaporizing liquid type extinguishers) may be either recovered for re-use in the extinguisher being serviced (provided that the extinguishing agent is not due for mandatory replacement), or discarded.






11.13 Powder Mixing Precautions 11.13.1 Mixing or cross-contamination of different types of powder, e.g. BE and ABE

types, is dangerous and shall be avoided.

11.14 Vaporizing Liquid Extinguishers 11.14.1 ‘Halon’ type extinguishers shall not be discharged to the atmosphere and only

those extinguishers that have been granted ‘essential use’ status may be pressure tested and returned to service (see 11.14.3).

11.14.2 Prior to any pressure test or service work on any vaporizing liquid type extinguisher that requires the contents to be removed, the contents shall be transferred from the extinguisher to a holding container by a method of recovery approved by the regulatory authority.

11.14.3 Regulatory authorities have banned the possession and use of ‘halon’ type vaporizing liquid fire extinguishers, unless ‘essential use’ status has been sought and granted for nominated extinguishers of this type.

11.15 Extinguisher Recharging 11.15.1 To ensure that adequate fire protection is maintained, extinguishers that have

been;

(a) found by inspection to be under pressurized

(b) found by test to be undercharged

(c) fully or partially discharged,

shall be recharged as soon as practicable in accordance with the manufacturer’s instructions.

11.16 Location Records

12 Passive Fire and Smoke Containment Systems

12.1 General 12.1.1 All Passive Fire and Smoke Containment Systems shall be inspected, maintained,

tested and surveyed at the frequencies indicated in MCSS 030200-03 Passive Fire and Smoke Containment Systems Maintenance Schedules.

12.1.2 This Section sets out the requirements for maintenance of passive fire and smoke containment systems comprising vertical and horizontal fire and smoke compartment barriers together with any openings, fire doors, fire shutters or any service penetrations and control joints preventing the passage of fire and smoke to other compartments.

12.1.3 These include, but are not limited to the following:

(a) Fire and smoke barriers—vertical and horizontal (including walls, floors, ceilings, bulkheads)

(b) Structural fire-resistant elements (beams, columns, girders, trusses, etc.)

(c) Fire-resistant doorsets (hinged and pivoted and horizontal sliding)

(d) Smoke doors (hinged and pivoted)






(e) Fire shutters

(f) Fire-rated glazing

(g) Access panels and ceiling hatches

(h) Ducts and dampers

(i) 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

12.2.1 General 12.2.1.1 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.

12.2.2 Compartment Integrity 12.2.2.1 The basis of maintenance for compartment integrity is to identify the

respective vertical and horizontal barriers and their respective fire-resistance 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.

12.2.3 Structural Fire Resistant elements 12.2.3.1 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.

(Extract From AS 1851)

12.3 High Use and Aggressive Environments 12.3.1 Passive fire and smoke containment systems located in high-use and aggressive

environments may require a higher frequency of maintenance than set out in the requirements of MCSS 030200-03 Passive Fire and Smoke Containment Systems Maintenance Schedules.

12.3.2 Note: The frequency of maintenance may need to be increased to satisfy the needs of the particular building as determined during the compilation of the essential services schedule.

12.3.3 For the purposes of this Section high use may be regarded as constant use, for a fire door, as an example, where building occupants travel from floor-to-floor using fire stairs on an hourly basis moving freely between compartments.






12.4 Design and Installation Survey

12.4.1 General 12.4.1.1 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.

12.4.1.2 Suitable documentation is to be produced and made available for the survey.

12.4.2 Compartmentation Integrity 12.4.2.1 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.

12.4.3 Structural fire integrity 12.4.3.1 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.

12.5 Marking, Labelling, Tagging and Signage

12.5.1 Fire Doors 12.5.1.1 Passive fire and smoke containment systems shall be labelled for

identification purposes.

a) Fire doorsets are required by AS 1905.1 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.

12.5.2 Compartment Barriers and Penetrations 12.5.2.1 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 030200-03.

13 Fire and Smoke Control Features of HVAC Systems

13.1 General 13.1.1 All Passive Fire and Smoke Containment Systems shall be inspected, maintained,

tested and surveyed at the frequencies indicated in MCSS 030200-04 Fire and Smoke Control of HVAC System Maintenance Schedules

13.1.2 This Section sets out the requirements for inspection, test, preventive maintenance and survey of fire and smoke control features of;

heating ventilation

air-conditioning (HVAC) systems in buildings,

13.1.3 This Section does not apply to air-conditioning, mechanical ventilation or natural ventilation systems that are not required to operate in fire and smoke control mode except that systems required to shut down in fire mode shall be proven to shut down in accordance with the Australian Standard.






13.2 Application 13.2.1 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.

13.2.2 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

Run Yes

Shutdown Refer Note 2 below

Air-handling

Optional N/A

13.2.3 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 1668.1 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.

13.2.4 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.






13.3 Design and Installation Survey 13.3.1 A survey is typically conducted visually from floor level or from an accessible

platform, or from an accessible roof, by simple observation through vent and fan discharges and is intended to identify changes to the HVAC system, or the building and its environment, that could affect the performance of the smoke control features of the HVAC system.

13.3.2 The goal of this survey is to ensure that the system can perform as originally intended and that performance capability is not compromised by occupancy, building alterations or HVAC alterations. Where an alteration has resulted in a change of the performance requirements, the system should be appraised against the modified performance requirements.

13.3.3 Fans that continue operating or stop in fire mode shall be included in the survey.

13.4 Dual Duty Systems 13.4.1 Systems or components that operate in normal HVAC duty and also have

dedicated fire mode duty, shall be inspected, tested and maintained to the requirements of MCSS 030200-04 Fire and Smoke Control of HVAC System Maintenance Schedules for day-to-day duty as well as dedicated fire-mode duty.

13.4.2 Failure of fire safety equipment can usually be attributed to one of three potential causes:

a) Wear and tear Prevention of failure due to wear and tear is usually addressed by regular inspections and appropriate maintenance or repair

b) Random event (environmental, material or usage).

Prevention of failure due to random events is usually addressed by inspection or testing, to demonstrate an acceptable level of performance at suitable intervals

c) Human error. Prevention of failure due to human error is usually addressed by training and education of responsible staff, monitoring of equipment status or regular inspection and testing

13.4.3 When HVAC equipment has been designed to provide fire and smoke control, the relative likelihood of the first two of these failure modes will depend on the pattern of usage.

13.4.4 Equipment used only for fire service duty will not be subject to the same level of wear and tear as equipment used for day-to-day HVAC duty, for comfort, health or process control. Hence, for reliable operation, equipment subjected to day-to-day usage will require more frequent inspections and maintenance or repair than equipment used only for fire service duty.

13.4.5 However, equipment used for day-to-day HVAC duty, is effectively monitored (tested) by the occupants of the building every day, and any breakdown is likely to cause occupant discomfort and generate corrective action to regain the required performance providing there is a current maintenance contract in place.






13.4.6 Equipment used only for fire service duty will not be subject to regular monitoring by occupants, and so will require frequent inspections or tests to establish confidence that it will be available to operate when needed, but will not require the same level of maintenance or repair as equipment used for day-to-day duty.

13.5 Documentation

13.5.1 General 13.5.1.1 Documentation covering maintenance records required to implement

Where a conflict arises between the requirements of this AS 1851 and this standard, and those of the manufacturer, the more stringent shall apply.

13.7 Forms for Recording Maintenance

13.7.1 General 13.7.1.1 Forms MCMF 030200-01 Figures Assessment of Essential Fire Safety

Measures – Fire Damper Maintenance Record, MCMF 030200-02 Essential Smoke Control Services – System Functionality Test Chart, MCMF 030200-03 Fire-Isolated Exit Pressurisation Systems Functionality Test Record and MCMF 030200-04 Fire-Isolated Exit Pressurisation Systems Performance Test Record provide examples of typical record documents required by this Section, the format of which may be used for recording purposes. Maintainer developed alternative layouts incorporating all the requirements of are acceptable.

13.7.1.2 The following applies to the use of smoke control functionality charts:

(a) Test indicator lamps to demonstrate On/Off fault. Fault may be tested by observing delay after manual override ‘Start’ or by isolating power before activating manual override.

(b) Where fans or dampers are individually activated by more than one fire alarm, allow a separate row in the chart for each activating alarm. For example, supply air detector, specifically zoned sprinkler alarm or return air detector that is not in the same zone as the occupied space detectors.

Note: See Column 4, ‘Design Comments’ and Column 21, ‘Comments on Tests’ of the chart shown in MCMF 030200-02 Essential Smoke Control Services – System Functionality Test Chart.

(c) In Columns 8 and 11, the inspector should indicate which smoke detector zone, sprinkler zone, supply air detector or specific smoke detector activated this operation.

(d) Smoke exhaust fans and exit pressurization systems to be tested at frequencies required by the regulatory authority to demonstrate that they are capable of performing to the Standard to which they were installed. This requires measurement of airflow rates, doorway velocities, door opening forces, restoration times, etc.

(e) The performance tests are to be carried out prior to the functionality tests, but within the maximum time period allowed under the relevant legislation. Document test results and methods used for testing separately, with a note in Column 21 indicating where performance test results are available, if not attached.






To indicate when performance tests are required, the relevant cell in Column 20 should be highlighted.

(f) In Column 4, charts should include:

(i) All air-conditioning and ventilation fans in the premises even if they simply shut down or continue running without manual or automatic control on fire alarm.

(ii) All smoke control make-up airflow paths. For example, motorized dampers, barometric (non-return) dampers, fixed intake grilles and doors that open automatically on fire alarm.

(iii) All motorized dampers that operate automatically during fire alarm, or have manual control from the fire fan control panel

Note: VAV dampers or ventilation dampers that have no fire mode operation need not be included.

(g) Smoke exhaust fans, pressurization fans, dampers (and some supply air fans) only operate if fire or smoke is detected in a specific zone and not when fire is detected in other zones. These functionality test charts allow verification of zone-specific activation from the ‘fire-affected zone’ and one ‘outside zone’. There will be many more ‘outside zones’ than fire-affected zones, so visual verification of non-operation for every device and every outside-zone could generate multitudes of tests, unless an effective procedure is established. Carry out at least one visual confirmation of fire ‘non-fire’ operation for each device. Confirmation of operation under other fire detection permutations may be verified by observation of indicator lamps (after their operation has been proved).

(h) The ‘non-operation’ verification procedure is to be attached to these charts and indicate, in Column 21, that those devices that were verified ‘non-operational’ when an associated fan or damper was confirmed to be operating.

(i) In a large project, the functionality charts may require many pages to cover all air handlers, dampers, smoke exhaust fans and sundry ventilation systems. Unless handled carefully, the sheer volume of documentation may cause difficulties during testing.

(j) Column 1 is to be used to show the reference used by the HVAC service provider or as shown on the HVAC drawings.

(k) Column 2 is to be used to show the name used by the building owner/manager to describe the relevant zone or area within the building.

(l) Column 3 is to be used to show the reference used by the fire services maintenance contractor to describe the relevant zone or zones.






13.7.2 Smoke Control Matrices 13.7.2.1 Smoke control matrices prepared by fire contractors show clearly and

unambiguously, the intended operation of HVAC systems under various different fire alarm conditions. However, limitations do occur and it is important for the documentation to make adequate provision for the following:

(a) Recording action when the alarm occurs in ‘another’ smoke zone.

(b) Recording action on ‘general fire alarm’ or sprinkler alarm.

(c) Recording if a fan / damper combination has manual override at FFCP.

(d) Recording if FFCP has indicator lamps for fan/damper combinations.

(e) Sufficient space to certify right / wrong operation on the sheet.

(f) Easy of reading, especially in low light test conditions.

(g) Written verification of fire alarm zone actuated.

13.8.5 Typical activities and skill sets 13.8.5.1 MCSS 030200-04 identifies what qualifications are required for the

various maintenance activities.

13.9 Functionality and performance tests 13.9.1 Testing of the fire and smoke control features of HVAC systems requires

verification of both functionality as well as performance of the components and the systems. For the purpose of this Section, functionality shall be demonstrated by a fan starting or stoping, a damper opening or closing, or an indicator lamp turning on/off. Performance is demonstrated by measurement of airflow velocity or volume flow rate, pressure difference between compartments, door opening force, etc.

13.9.2 MCSS 030200-04 provides for elementary testing procedures that may be used in some cases for ‘Partial Simulation’ tests, but in the case of ‘Full Simulation’ tests, accurate measurements of the performance parameters shall be taken.

(b) AHU 23 stops on General Fire Alarm.

13.9.3.2 Performance

(a) Fan #1A delivers 20,000 L/s in fire mode operation

(b) Pressure in Zone A is 20 Pa below Zone B on fire alarm in Zone A.

13.10 FREQUENCY

13.10.1 Inspection, preventive maintenance and records 13.10.1.1 The fire and smoke control features of all HVAC systems shall be

subjected to inspection and preventive maintenance in accordance with Clauses MCSS 030200-04 Fire and Smoke Control of HVAC System Maintenance Schedules.

13.10.1.2 Corrective maintenance, where required, includes removal, repair, replacement, lubrication or adjustment as appropriate.

13.10.1.3 Notes:

a) In the case of HVAC systems used for smoke control, the inspection, testing, preventive maintenance and survey work should be a carried out such that inspection, preventive maintenance and surveys are applied to components or equipment, and testing is applied to whole systems.

Apart from gross failures such as broken belt drives or collapsed bearings, most of the preventive maintenance work on HVAC systems depends on the skill and experience of qualified technicians recognizing, after inspection, that preventive maintenance or replacement of consumables is necessary. Hence, preventive maintenance work is not specified at prescribed intervals, rather, it is specified by noting ‘remove, repair, replace or adjust as necessary’. Where action is taken during inspection to successfully rectify or repair a component, then ‘pass’ is to be recorded in the ‘pass/fail’ column and details of the action taken is to be entered in the ‘Comments’ column.

b) Apart from gross failures such as broken belt drives or collapsed bearings, most of the preventive maintenance work on HVAC systems depends on the skill and experience of qualified technicians recognizing, after inspection, test or survey, that repair, adjustment, etc., of components or replacement of consumables is necessary. Hence, preventive maintenance work is not specified at prescribed intervals, rather, it depends on an inspection to ascertain the condition of the plant, followed by adjustment, correction or even repair where, in the judgment of the experienced technician, such actions are necessary, and this is the intention of the schedules in MCSS 030200-04 Fire and Smoke Control of HVAC System Schedules.






Where action is taken during inspection to successfully rectify or repair a component, then ‘pass’ is to be recorded in the ‘Pass/fail’ column and details of the action taken are to be entered in the ‘Comments’ column.

c) Maintenance should be completed at the specified intervals and to the standard required by the equipment manufacturer and scheduled in the project’s operation and maintenance manuals.

In HVAC systems, much of the maintenance is carried out when required; hence, inspections need to be carried out prior to considering the scheduled maintenance activity. For example, belt tensioning is carried out when inspection shows it is needed, rather than regular tightening without assessment, which could do more damage than leaving the belts loose.
