Citation\n\nThese regulations may be cited as the *Environmental Protection (Abrasive Blasting) Regulations 1998* 1.\n\n##### 2. Interpretation\n\nIn these regulations —\n\n  abrasive blasting means cleaning or abrading the surface of an object using an abrasive material propelled by compressed air, water or steam or by a wheel;\n\n  aquatic environment means any watery environment including marine, estuarine and riverine environments;\n\n  blasting chamber means a fully enclosed structure in which abrasive blasting is carried on;\n\n  dry abrasive blasting means abrasive blasting during which no water is added to the abrasive material or the propellent;\n\n  operator means a person carrying on abrasive blasting;\n\n  waste material means used abrasive, abraded material, waste generated by cleaning an object prior to blasting, and any other waste products created during abrasive blasting, including waste collected in a dust extractor, settling pond or tank, or holding sump;\n\n  wet abrasive blasting means abrasive blasting during which water is added to the abrasive material or its propellent or is used as the propellent;\n\n  wet scrubber means a device in which water or other liquid is used to remove particulate matter from a gas stream.\n\n(2) In these regulations a reference to abrasive blasting being carried on in the open is a reference to abrasive blasting being carried on other than in a blasting chamber.\n\n##### 3. Prohibition on the use of certain materials\n\nAn operator must not use —\n\n(a) any material containing 2% or more free silica (crystalline silicon dioxide) in abrasive blasting; or\n\n(b) corrosion inhibitors containing chromate, nitrate or nitrite in wet abrasive blasting.\n\n##### 4. Blasting chambers to be used if possible\n\nAn operator must carry on all abrasive blasting in a blasting chamber unless such a chamber cannot reasonably be used because of the size, shape, position or location of the object being blasted.\n\n##### 5. Blasting chambers\n\nAn operator must ensure that a blasting chamber —\n\n(a) is completely sealed; or\n\n(b) is fitted with a mechanical ventilation and dust extraction system which is operating so that —\n\n(i) no visible dust escapes from the blasting chamber;\n\n(ii) all air from the blasting chamber passes through the ventilation and dust extraction system before being discharged into the environment; and\n\n(iii) air discharged into the environment does not contain any visible dust or more than 50 milligrams of particulate matter per cubic metre.\n\n(2) If the ventilation and dust extraction system for a blasting chamber includes a wet scrubber the operator must ensure that —\n\n(a) waste water from the scrubber is drained into, and contained in, settling tanks or ponds until all particulate matter has settled out; and\n\n(b) the settling ponds or tanks are emptied as often as necessary to ensure their efficient operation.\n\n##### 6. Abrasive blasting in the open\n\nAn operator must not carry on abrasive blasting in the open unless it is carried on in such a manner that no visible dust escapes from the premises at which the blasting is carried on (or if there are no defined boundaries to the premises, no such dust escapes onto any place to which the public has access).\n\n##### 7. Abrasive blasting in or near aquatic environments\n\n(1) This regulation only applies to abrasive blasting operations which involve the use or removal of organotin or other heavy metal protective coatings.\n\n(2) An operator must not carry on abrasive blasting in or near an aquatic environment unless the size, shape, position or location of the object being blasted makes it impracticable to move the object out of, or away from, that environment.\n\n(3) An operator carrying on abrasive blasting in or near an aquatic environment must ensure that all water which may contain waste material is drained into, and contained in, an impervious holding sump until it is disposed of in accordance with regulation 8.\n\n(4) An operator must ensure that —\n\n(a) any overflow from the holding sump will drain into a soakwell; and\n\n(b) the holding sump and soakwell are emptied as often as necessary to ensure their efficient operation.\n\n##### 8. Waste disposal\n\nAn operator must ensure that —\n\n(a) all waste material is cleaned up at the conclusion of each abrasive blasting operation;\n\n(b) no waste material escapes from the premises at which the blasting is carried on (or if there are no defined boundaries to the premises, no waste material escapes onto any place to which the public has access); and\n\n(c) all waste material is disposed of at an appropriate landfill site or waste treatment facility the occupier of which holds a licence under Part V of the Act in respect of that site or facility.\n\n##### 9. Offences and penalties\n\nA person who contravenes any of these regulations commits an offence.\n\nPenalty: $5 000.\n\n[Regulation 9 amended: Gazette 11 Dec 1998 p. 6614.]\n\n##### 10. Repeal\n\nThe *Sandblasting Operations Regulations* are repealed.\n\nNotes\n\n1 This reprint is a compilation as at 2 April 2004 of the *Environmental Protection (Abrasive Blasting) Regulations 1998* and includes the amendments made by the other written laws referred to in the following table.

The 1998 regulations replaced the earlier Sandblasting Operations Regulations (repealed by Regulation 10) without significant expansion of scope. The amendments shown in the compilation table (December 1998) appear to be minor technical adjustments to penalty provisions rather than substantive scope changes."},"complexity_factors":["Short length: only 10 regulations spanning 4-5 pages","Minimal cross-referencing: only one reference to Part V of the parent Act (licensing)","Simple structure: linear progression from definitions to specific operational requirements","Limited conditional logic: primarily straightforward prohibitions ('must not') and positive duties ('must ensure')","Only 8 defined terms in the interpretation section, all clearly explained","No nested exceptions or complex definitional chains","Single penalty provision applying uniformly to all contraventions"],"plain_english_summary":"**What this legislation does:**\n\nThese regulations control how businesses and workers carry out **abrasive blasting** — the process of cleaning or roughening surfaces by firing abrasive materials (like sand or grit) at high speed using compressed air, water, or steam. Think of it like high-pressure sandblasting used on ships, bridges, or industrial equipment.\n\n**Key rules:**\n\n*   **Banned materials:** Operators cannot use blasting materials containing 2% or more **free silica** (a dangerous dust that causes lung disease) or certain corrosion inhibitors containing chromates, nitrates, or nitrites when wet blasting.\n*   **Use enclosed chambers:** Blasting must be done inside fully enclosed **blasting chambers** whenever reasonably possible. These chambers must be sealed or have ventilation systems that prevent visible dust escaping and limit particle emissions to 50 milligrams per cubic metre.\n*   **Outdoor restrictions:** If blasting must happen outdoors (\"in the open\"), no visible dust can escape from the worksite or into public areas.\n*   **Protection for waterways:** Special rules apply when blasting involves removing **organotin** or heavy metal coatings (like old ship paint) near water. Operators must prevent contaminated water from entering rivers, oceans, or estuaries by using sealed holding tanks.\n*   **Waste cleanup:** All waste — used abrasive, dust, and debris — must be cleaned up after each job and disposed of at licensed waste facilities.\n\n**Who it affects:**\n\n*   Industrial operators conducting abrasive blasting\n*   Businesses in ship repair, construction, and heavy manufacturing\n*   Workers exposed to blasting dust and chemicals\n\n**Why it matters:**\n\nThese rules protect workers from deadly **silicosis** (lung scarring from silica dust), prevent toxic heavy metals from polluting waterways, and stop nuisance dust affecting neighbouring properties and public spaces. The regulations replaced older \"Sandblasting Operations Regulations\" to modernise environmental and health protections."},"summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"Scope cannot be assessed — the full text of the regulations was not retrievable.
