One of the more obvious changes from the 2004 edition was the introduction of a new Section Two— Performance-based design and other essential requirements. The additional section provides a new path for compliance, based on demonstrating compliance with performance-based requirements for installations where Means of Compliance requirements in sections three to six are not possible or necessary to achieve. While it is expected that Means of Compliance will remain the default method for most installations, performance requirements provide a new path for installations with innovative technology or other reasons for not being able to directly comply with the Means of Compliance requirements. Means of Compliance The Means of Compliance sections contain prescriptive requirements, for which a combination of experience, history and calculations have already shown will produce safe and reliable installations. In contrast, performance-based requirements are based on the high level safety and operational objectives that must be achieved, without specifying or limiting how the objective may be achieved. This provides a high level of flexibility for the installation, although an equally high level of responsibility is placed on the installer to ensure all aspects of the performance base requirement have been addressed, without causing detriment to other aspects of the installation. It is important to be aware that performancebased requirements offer an alternative means for demonstrating compliance and are not an option for installations that are simply not compliant. In particular, the installer using performancebased requirements is obliged to ensure that the level of safety, convenience and efficiency of operation for installations is not less than for installations that comply with the prescribed means of compliance. Exemption process In the past installations that did not comply with the prescriptive means of compliance requirements required an application for exemptions (schedule 6) under the Gas Safety Act. The exemption process still exists and remains the only option for installations that are directly non-compliant. For installations where performance-based and exemption application approaches are both possible, it is up to the installer to choose which path they prefer. Alternative solutions for complex gas installations must be assessed by ESV to ensure they meet the performance requirements of the installation. The Victorian Building Authority (VBA) should be contacted when considering alternative solutions for standard gas installations. ESV requirements for alternative solutions ESV requires all alternative solutions that are based on performance requirements to be accompanied by documentation. The documentation should outline the scope of work the alternative solution relates to as well as: »» the performance requirements that the alternative solution is required to meet »» identification of the relevant deemed-to-satisfy clause »» documents relied on to substantiate the alternative solution proposal including, where relevant, NATA-accredited test reports and expert judgments »» other evidence that is being relied upon to support the alternative solution. The level of documentation and evidence required will depend on the nature of the installation and the performance requirement being addressed. All documentation must be kept by the gasfitter for seven years. Assessment methods Assessment methods for each installation are determined based on the complexity of the alternative solution design and performance requirements to be achieved. Assessment methods may include: »» review of documentary evidence »» verification of methods »» independent expert judgment methods »» comparison to the deemed-to-satisfy requirements. Submissions will be reviewed on a caseby-case basis and no guarantee is given that a performance-based approach will be accepted by ESV. If a performance-based approach is being considered it is recommended that ESV be contacted and advised early on in the process.    Please contact the Gas Technical Information Helpline on 1800 625 563 for further information. NMIT: Training gasfitters for today and tomorrow By Doug Rennie, ESV Gas Inspector From modest beginnings, the Northern Melbourne Institute of TAFE (NMIT) recently celebrated 100 years of quality trade training. Today NMIT is one of Victoria’s leading training providers for gasfitters. With the continued partnership and support of ESV, NMIT’s dedicated staff are proud to offer a variety of courses in gasfitting. NMIT training provides: »» plumbing and gasfitting apprenticeships »» registration with the Victorian Building Authority in gasfitting »» the opportunity to obtain a licence with the Victorian Building Authority in gasfitting »» gas conversion work »» licence renewal with the Victorian Building Authority for previously licenced gasfitters. NMIT’s teaching staff are fully qualified in all areas of plumbing and gasfitting. NMIT facilities include state-of-the-art work stations and equipment. Training is focused on a combination of technical information and hands-on practice, and at all times the NMIT teaching staff seek the advice and support of ESV. For more information on existing courses or new courses contact the plumbing and gasfitting staff at NMIT on (03) 9269 8633.
