This allowed the ACT\nLegislative Assembly to amend and repeal the laws. The Machinery Ordinance\n1949 and the Boilers and Pressure Vessels Regulations were converted into ACT\nenactments on 11 May 1989 (self-government day).\nAs with most ordinances in force in the ACT, the name was changed from\nOrdinance to Act by the Self-Government (Citation of Laws) Act 1989 A1989-21, s\n5 on 11 May 1989 (self-government day).\nThis regulation was renamed under the Legislation Act 2001.\nBefore 12 September 2001, regulations commenced on their notification day unless\notherwise stated (see Interpretation Ordinance 1937 s 16, Interpretation Act 1967\ns 50, Subordinate Laws Act 1989 s 6).\nLegislation before becoming Territory enactment\nBoilers and Pressure Vessels Regulation 1954 SL1954-12\nnotified 26 August 1954\ncommenced 15 March 1955 (s 2 and Cwlth Gaz 1955 p 510)\nas amended by\nAmendments of the Boilers and Pressure Vessels Regulations\nSL1959-17\nnotified 31 December 1959\ncommenced 31 December 1959\nRegulations to repeal certain Regulations and to revise certain\nRegulations in force under the Ordinances of the Australian Capital\nTerritory SL1980-3 (as am SL1980-14) sch\nnotified 25 March 1980\ncommenced 25 March 1980\nRegulations to amend Regulations 1980 No 3 SL1980-14 sch\nnotified 9 October 1980\ntaken to have commenced 25 March 1980\n\nEndnotes\n4 Amendment history\npage 28 Boilers and Pressure Vessels Regulation 1954\nEffective: 01/03/11\nR6\n01/03/11\nAuthorised by the ACT Parliamentary Counsel—also accessible at www.legislation.act.gov.au\nBoilers and Pressure Vessels Regulations (Amendment) SL1982-33\nnotified 18 August 1982\ncommenced 18 August 1982\nBoilers and Pressure Vessels Regulations (Amendment) SL1983-11\nnotified 30 September 1983\ncommenced 1 October 1983 (s 1)\nLegislation after becoming Territory enactment\nStatutory Offices (Miscellaneous Provisions) Act 1994 A1994-97 sch\npt 2\nnotified 15 December 1994 (Gaz 1994 No S280)\ns 1, s 2 commenced 15 December 1994 (s 2 (1))\nsch pt 2 commenced 15 December 1994 (s 2 (2) and Gaz 1994\nNo S293)\nOccupational Health and Safety Legislation Regulations Amendment\nSL2000-47 pt 2\nnotified 30 November 2000 (Gaz 2000 No 48)\ncommenced 30 November 2000 (s 1)\nLegislation (Consequential Amendments) Act 2001 A2001-44 pt 235\nnotified 26 July 2001 (Gaz 2001 No 30)\ns 1, s 2 commenced 26 July 2001 (IA s 10B)\npt 235 commenced 12 September 2001 (s 2 and see Gaz 2001\nNo S65)\nStatute Law Amendment Act 2007 A2007-3 sch 3 pt 3.12\nnotified LR 22 March 2007\ns 1, s 2 taken to have commenced 1 July 2006 (LA s 75 (2))\nsch 3 pt 3.12 commenced 12 April 2007 (s 2 (1))\nStatute Law Amendment Act 2011 A2011-3 sch 3 pt 3.4\nnotified LR 22 February 2011\ns 1, s 2 commenced 22 February 2011 (LA s 75 (1))\nsch 3 pt 3.4 commenced 1 March 2011 (s 2)\n4 Amendment history\nName of regulation\ns 1 sub SL2000-47 s 3\n\nEndnotes\nAmendment history 4\nR6\n01/03/11\nBoilers and Pressure Vessels Regulation 1954\nEffective: 01/03/11\npage 29\nAuthorised by the ACT Parliamentary Counsel—also accessible at www.legislation.act.gov.au\nam R4 LA\nDictionary\ns 2 sub SL2000-47 s 3\nam A2001-44 amdt 1.2740\nNotes\ns 3 om SL1980-3\nins A2007-3 amdt 3.53\nRepeal\ns 4 om SL2000-47 s 3\nInterpretation\ns 5 am SL1959-17;

Operators carry the compliance costs: purchasing and maintaining required fittings, arranging inspections and tests, complying with repair and isolation notices, and notifying the chief inspector of events (ss 7, 24, 31, 35, 42–45).\n- Inspectors and the chief inspector: given discretion to require fittings, conduct inspections (including drilling test holes), order hydrostatic or other tests, and to suspend or cancel certificates (ss 16, 29, 34, 42, 26).\n- Secondary parties: businesses that perform inspections, testing, repairs and supply safety fittings; and persons working around boilers who must follow safety directions during inspections (ss 31–33).\n\nWhy it matters (official rationale and practical effects)\n\n- The regulation is presented as a public-safety instrument: it limits the risk of explosions, leaks, fires and related injury or property damage by prescribing minimum fittings, inspection regimes and operational controls (see Part 2 and Part 3). That is the stated purpose in the structure and the powers given to inspectors.\n\n- Practical trade-offs and incentives:\n  - Who pays: operators pay for compliance (installation of fittings, repairs, periodic testing and inspections) (ss 7, 31, 42).\n  - Who decides: inspectors and the chief inspector exercise technical judgment on required devices, tests and when a certificate should be suspended or cancelled (ss 16, 26, 35). The Minister can grant exemptions (s 6) and hear appeals against inspector notices (s 36).\n  - Compliance burden: annual (12‑month) certificate cycles (s 25), pre-inspection preparation and possible hydrostatic tests (ss 25, 31, 42) impose recurring costs and downtime for operators.\n  - Market effects: creates demand for inspection, testing and repair services, and enforces minimum equipment standards that suppliers and operators must meet (ss 7, 16, 42).\n  - Administrative discretion and implementation risk: many provisions grant broad written-direction powers to inspectors (for example to require additional fittings (s 7(g)) or to direct access removal and drilling of holes (ss 31, 34)). That discretion can produce variation in enforcement and uncertainty for operators about the exact standard until an inspector acts.\n  - Opportunity costs and substitution effects: small operators or informal uses of boilers/pressure vessels may be deterred or require investment to comply; some specific low‑risk items are explicitly exempted (s 6), and the Minister may grant further exemptions under conditions.\n\nConcrete behavioural changes the regulation requires\n\n- Operators must fit and maintain specified safety equipment (s 7, ss 16–17), keep the registered number legible (s 28) and exhibit the certificate of inspection (s 27).\n- Operators must allow inspections, prepare the plant for internal inspection, and not conceal defects (ss 30–34).\n- If an inspector issues a notice, operators must follow it or appeal promptly (ss 35–36).\n\nSelected specific mechanics and limits\n\n- Certificates: issued only after an inspector is satisfied the plant is safe; first issue attracts a registered number that must be stamped or plate‑attached to the plant (s 24, s 28). Certificates generally last 12 months (s 25) but the chief inspector can extend them short-term when re‑inspection cannot be completed (s 25(2)).\n- Testing: hydrostatic testing is the default; non‑water testing requires the chief inspector's written permission (s 42(3)–(4)). Operators must report test results to the chief inspector (s 42(5)).\n- Enforcement: inspectors may drill test holes in plate to measure thickness; the operator must plug holes afterwards to the inspector's satisfaction (s 34).\n- Appeals: operators have 7 days to appeal a notice requiring repair or cessation to the Minister; the Minister may vary or dismiss the appeal (s 36).\n- Penalty for contravention or obstruction: stated maximum is $100 (s 50). Note: the front material to the republication also records penalty‑unit values under the Legislation Act for offence valuation at that date.\n\nComparing the instrument’s stated purpose and costs\n\n- The regulation clearly prioritises accident prevention by mandating hardware standards and a regular inspection regime. The costs of that approach fall directly on operators in the form of capital, maintenance and administrative compliance costs (ss 7, 24, 31, 42).\n- The regulation centralises technical judgement with inspectors and the chief inspector (ss 16, 26, 29–36). That structure helps tailor interventions to particular plant but increases reliance on regulatory discretion, which creates potential variability in compliance expectations and enforcement costs for operators.\n\nKey sections for quick reference: mandatory fittings and valves (s 7, ss 16–17), certificates and registration (ss 22–25, 28), inspectors’ powers and notice/appeal mechanisms (ss 29–36), testing and notification duties (s 42, ss 43–45)."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
