28 Labelling & Paperwork Where practical, all fire stopping system should be labelled for identification purposes to assist with ongoing maintenance (ongoing inspection and testing as appropriate). Although the requirements in AS4072 Part 1 are only contained in an informative Appendix, it is highly recommended that fire stopping systems are labelled. To assist with certification and to provide a suitable platform for subsequent maintenance and evidence of compliance schedule should be provided by the installation companies at the time fire stopping systems are employed into buildings. These would be accompanied or reference fire compartment drawings and each penetration or cluster of services should have a unique identification number. Good workmanship It might sound obvious but an important element of a fire stopping system is good workmanship. This can be translated into competent installers with adequate training, knowledge of the fire stopping product and fire stopping systems in question. In short, someone who takes pride in their workmanship and has the appropriate skills is required to install and / or maintain fire stopping systems In some States and Territories, competencies translate in formal accreditation and licensing requirements. The evidence of compliance certificate, provided to certify the works should be accompanies with the detailed schedules listed above. Appropriate labelling and paper work to support certification of fire stopping systems is an important part of an overall and acceptable installation Version 1a—March 2006
29 Australasian Regulatory Requirements Building Code of Australia In each State & Territory of Australia, the Technical Provisions relating to Building Control are contained within the Building Code of Australia, commonly referred to as the BCA. The BCA divides building into Classes, which relate to the use of the Building, and for each building Class, the Type of Construction is determined from the rise in storeys for the building in question. For a given Class, and construction Type, (eg Class 2, Type A Construction), the BCA in the deemed-tosatisfy or prescriptive provisions, provides the relevant Fire Resistance Level (FRL) or “fire rating” for different compartment barriers. Building Code of New Zealand The New Zealand Building Code (NZBC) works in much the same manner as the BCA using Purpose Groups in lieu of Classes. Fire Ratings The required Fire Resistance Level, (FRL) for a specific fire resistant barrier, in which an opening or penetration exists, with and without multiple service penetrations, is determined in accordance with Section C of the Building Code of Australia (BCA). In short, the principal is that the FRL of the fire resistant barrier (wall, floor or ceiling) must not be compromised by and opening and/or service penetration(s), except for specific exemption provided within the Building Code of Australia. Fire-resistance level (FRL) means the grading periods in minutes determined in accordance with Specification A2.3, for the following criteria— (a) structural adequacy; and (b) integrity; and (c) insulation, and expressed in that order. Compartmentalisation The BCA uses Fire Resistance Levels (FRLs) to nominate the required fire rating for different fire resistant barriers within a given fire compartment. The BCA definition of an FRL is as follows: Due to the fact that most penetration sealing systems are not structural elements, (they are not designed and should not carry any structural building loads), these penetrations are not required to have a rating for structural adequacy and this part of the FRL is usually designated with a dash (“-“). The BCA also provides some dispensation for insulation, which is the non-exposed side temperature rise, allowing some penetrations not to require an insulation part of the required FRL either (eg. Wall mounted fire dampers).
