Fire Extinguishers to supersede AS 1851.1—1989, Maintenance of fire protection equipment, Part 1: Portable fire extinguishers This Standard is the result of a consensus among representatives on the Joint Committee to provide it as an Australian Standard This edition of the Standard includes a maintenance schedule for fire blankets and maintains the concept of periodicity of inspection and servicing for fire extinguishers formerly referred to as ‘levels of inspection and servicing’ The periods are on a time-elapsed basis and range, depending on the extinguisher type, from six-monthly inspections to six-yearly inspections The maintenance schedule tables are no longer grouped according to the different types of extinguishers; instead, they are now in terms of maintenance periods Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited With the publication of AS 1851.1–1985, the maintenance of all chemical fire extinguishers was brought to a common cyclic routine, i.e six-monthly, yearly, three-yearly as appropriate, and six-yearly This replaced the timetables in AS 1851, Part 1—1976 which gave no easy correlation between the maintenance periods of various types of extinguishers Requirements for the charging of new extinguishers shipped empty are given in AS 1841, Portable fire extinguishers Installation procedures and requirements, and signs, are specified in AS 2444, Portable fire extinguishers—Selection and location A companion Standard to provide guidance on servicing of portable fire extinguishers is available (AS 3676— 1989, Portable fire extinguishers—Guide to servicing) and will assist in the general duties, training, and certification of personnel expected to service and maintain portable fire extinguishers In 1979, Standards controlling the manufacture of extinguishers were upgraded significantly and Standards Australia became directly involved through the quality assurance and certification scheme and the application of a unique identification label  Copyri ght STANDARDS AUSTRALIA Users of Standards are reminded that copyri ght subsists in all Standards

general servicing of portable fire extinguishers that, at the time of manufacture, complied with the contemporary edition of the relevant Standard listed in Table 1.1 For fire extinguishers used regularly for demonstration and training, maintenance should be more frequent than specified due to the increased potential for wear and damage When pressure testing operating heads (valves), components such as pressure indicators are disassembled which results in the pressure test not reflecting the pressure retention characteristics of the complete assembly This Standard also includes a maintenance schedule for fire blankets complying with the requirements of AS 3504 and intended for use on small fires involving cooking oil, fats and clothing TABLE 1.1 RELEVANT AUSTRALIAN STANDARD*

take the form of — (i) a logbook; (ii) a computer-based record system; or (iii) other permanent record system that is capable of easy interpretation or generally has easily interpreted reports and is to be cross-referenced against an individual extinguisher The maintenance record shall be available for the property at all times Where a logbook is used, it shall be substantially bound, but not in loose leaf formats, and shall have numbered pages in triplicate The logbook shall include the signature of the owner or agent and the service person, and have the required distribution of copies printed on each page, i.e.: (A) Original — owner/occupier/agent (B) Duplicate — service person (C) Triplicate —retain in book The use of maintenance record tags does not preclude the need for a separate maintenance record system 2.1.4 Reporting A report including any discrepancy in location, type, size, rating and identification mark during servicing shall be provided to the owner of the equipment in writing COPYRIGHT AS 1851.1 — 1995 2.1.5 Personnel All maintenance work is required to be carried out by experienced personnel in accordance with recognized safety procedures Persons with the necessary training and experience, with access to the requisite tools, equipment and information, and capable of carrying out the inspection and maintenance procedures of this Standard, are considered to be experienced personnel Pressure testing or charging of any unit is to be done only in designed safety cages of a strength sufficient to contain all fragments given off by possible vessel rupture or failure NOTE: Maintenance of halon fire extinguishers should be carried out by specifically trained and registered personnel 2.1.6 Waste products It should be noted that the waste products of the servicing of fire extinguishers, and particularly from discharge testing, will generally be the subject of State legislation dealing with the disposal of trade wastes Legislation controlling the transfer, handling, storage, sale and ownership of halons exist in most Australian States In disposing of waste material, individuals or organizations servicing fire extinguishers should familiarize themselves with the applicable legislation and ensure that this is complied with 2.2 INSPECTION AND SERVICE Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited 2.2.1 Classification For maintenance record tag purposes, maintenance work involving inspection and servicing shall be classified according to inspection and service intervals as follows (see Clause 2.2.2): (a) The Number ‘1’ shall denote 6-monthly intervals (b) The Number ‘2’ shall denote yearly intervals (c) The Number ‘3’ shall denote 3-yearly intervals (d) The Number ‘4’ shall denote 6-yearly intervals (e) The Number ‘5’ shall denote ‘after-use’ procedures 2.2.2 Periodicity of maintenance procedures The periodicity of the different intervals of maintenance of extinguishers shall be as set out in the appropriate maintenance schedules in Section and referred to as Levels to For halon-type extinguishers only, the initial six-yearly maintenance procedure may be extended to, but not exceed, 12 years Such an extension of maintenance procedures shall apply only to extinguishers that are installed in locations which are not subject to environmental conditions which may result in extinguisher deterioration Any extension of maintenance procedures beyond six years shall be by mutual agreement between the appropriate maintenance contractor and the extinguisher owner Following the initial maintenance interval as given above, the normal intervals of maintenance shall apply CAUTION: HALON FIRE EXTINGUISHER SHALL NOT BE DISCHARGED TO ATMOSPHERE AND ONLY THOSE GRANTED ESSENTIAL USE STATUS MAY BE PRESSURE TESTED AND RETURNED TO SERVICE BY THE FOLLOWING METHOD: (I) EMPTY THE EXTINGUISHER BY TRANSFERRING THE CONTENTS TO A HOLDING CONTAINER (II) PRESSURE TEST, SERVICE AND RECHARGE IN ACCORDANCE WITH TABLE 3.1 NOTE: The extended periodicity on halon extinguishers was granted to prevent unnecessary discharge during maintenance leading to ozone depletion Commencement of the maintenance schedules given in Section shall be based on the pressure test at the time of manufacture of the extinguisher, or the month and year of the last pressure test, whichever is the later If the date of manufacture or last pressure test is unknown, a six-yearly maintenance procedure shall be applied to the extinguisher Upon installation, a Level inspection shall be carried out COPYRIGHT Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited AS 1851.1 — 1995 The periodicity of extinguisher servicing requires that every six years the unit is discharged or emptied and subjected to a periodic pressure test of 1.5 times the working pressure Mpa, the marked test pressure whichever is the greater, as described in Item 18 of Table 3.1 Extinguishers discharged during this period may be recharged without pressure-testing subject to the six-yearly cycle being adhered to However, for extinguishers discharged after the fourth year of the six-year period, it is recommended that a pressure test be carried out to allow the extinguisher to begin a new six-year cycle Where the maintenance status of an extinguisher cannot be reliably re-established, a sixyearly maintenance procedure shall be carried out on the extinguisher and recorded in accordance with the appropriate requirements of this section 2.2.3 Additional maintenance procedures 2.2.3.1 Aggressive environment Unless protected from the effects of an aggressive environment, extinguishers located in such environments shall be subject to a more comprehensive maintenance schedule by conducting a six-yearly (Level 4) inspection every three years as set out in Section (see Table 3.1) Aggressive service environments include the following or as defined by the regulatory authority: (a) Exterior situations exposed to the sun, ultraviolet radiation, wind, rain, or salt spray (b) Corrosive atmospheres (c) Abnormally dusty or moisture-laden atmospheres (d) Environments which subject the extinguisher to continuous or intense vibrations (e) Environments having extremes of temperature 2.2.3.2 Organic Lining Where any cylinder lining is found to be suspect as to its soundness upon routine examination, it shall be subjected to a continuity test carried out in accordance with AS 1841.1 and in any case at least every level-4 service 2.2.3.3 Water quality In some areas, the water supply, while fit for human consumption, may be unsatisfactory for prolonged contact under pressure with water-type fire extinguisher cylinders (which are typically welded 304 stainless steel) In such areas, either specially treated cylinders shall be used, or a corrosion inhibitor should be added to each charge in the extinguisher Adelaide and Perth are examples of areas where this is likely, and extinguishers sold in these areas should be supplied with the appropriate treatment Detailed advice on what treatment might be appropriate should be sought from extinguisher manufacturers If in any doubt as to the water quality, an inhibitor should be added Failure to so sometimes results in rapid deterioration of the extinguisher, leading to leakage or failure to operate The use of hard water, in places where water quality has proved to be a problem, or is likely to be a problem, and salts that are deposited in extinguishers, the maximum periodicity of maintenance should be revised so that maintenance schedules occur at more frequent intervals NOTE: The presence of salts in extinguishers can clog the pressure indicator filter, bind the actuation mechanism, inhibit the removal of the operating head or lead to the corrosion of extinguisher components 2.2.4 After-use procedures Recharging after use shall be carried out in accordance with the ‘after-use’ routine specified in the maintenance schedules For guidance, see AS 3676 NOTE: Recharging should be carried out immediately after use or partial use in order to maintain protection and minimize potential corrosion damage 2.2.5 Exceptions Aerosol and non-rechargeable type fire extinguishers shall be required to undergo all inspection routines except those requiring the removal of the operating head, depressurizing, inspection of contents or the interior of the extinguisher COPYRIGHT 2.3 AS 1851.1 — 1995 EVIDENCE OF COMPLIANCE 2.3.1 Records Records that are required to be kept (see Clause 2.1.3) shall provide evidence of compliance with this Standard 2.3.2 Maintenance record tag Where used, the classification, year and month of all maintenance work carried out shall be recorded on a metal tag as shown in Figure 2.1 The tag shall be made of a suitable metal and shall be not less than 0.3 mm thick; plastics shall not be used unless permitted by the regulatory authority The lettering, figures, and lines on the tag shall be printed in black over a continuous background of approximately Golden Yellow Y14 as specified in AS 2700 The tag shall not carry any information other than that shown in Figure 2.1 (a) and the recorded information specified in this Clause An example of a maintenance record tag marked with six years if service levels is shown in Figure 2.1(b) Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network

routine was performed, with a figure not less than mm high recessed or projecting not less than 0.1 mm either side of the tag However, six-monthly maintenance may be indicated either by an etched, embossed, or stamped figure ‘1’, or by a punched hole in the tag When a new maintenance record tag is provided, the final-year maintenance record and last hydrostatic test date shall be transferred from the expired tag or service record to the new tag by a hole punched in the pressure test column at the appropriate year The tag shall be attached to the extinguisher so that the force necessary to detach the tag is not less than 500 N When ordering maintenance record tags, the year on the main body of the tag shall commence with the previous year, capturing the record of the previous year’s service history Pressure test history shall end at the year before the first year given on the main body of the tag COPYRIGHT Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage,
