Background 1.1. The Group Standards Site and Storage Conditions for Aerosols were established in July 2006 (“the Conditions”). The Conditions are incorporated by reference into the Group Standards listed in Appendix 1. The full text of the Site and Storage Conditions for Aerosols is available from the EPA website1. 1.2. The Environmental Protection Authority (“the Authority”) is now proposing to amend the Site and Storage Conditions for Aerosols and is requesting submissions on the proposal and its assessment. 2. Basis for the proposed amendments 2.1. Clause 25 of the Conditions requires that a building holding more than an aggregate quantity of 3000 litres (water capacity) of flammable aerosols must be separated from the boundary of the controlled zone by a distance of 3 metres. 2.2. It is proposed that alternatives to the 3 metre separation requirement be added to the Conditions that provide equivalent levels of mitigation of the adverse effects of aerosol storage, taking account of the quantity of aerosols held, the nature of the building or room construction where the aerosols are held, and the provision of risk mitigating features such as fire protection. 2.3. The alternative solutions draw on cases provided in the following standards: National Fire Protection Association (NFPA) 30B “Code for the manufacture and storage of aerosols” 2007; and AS/NZS 3833: 2007 “The storage and handling of mixed classes of dangerous goods in packages and intermediate bulk containers”. The details of the proposed alternative solutions are given below in section 3. 2.4. It is also proposed that Part 2 of the Conditions be deleted as it has no practical effect. 2.5. The interpretation section of the Conditions will be amended to add a definition for fire resistance rating (FRR) and to formally incorporate the correction to the definition of “area of high intensity land use” issued in November 2006. 2.6. If approved by the Authority, the proposals would form part of the Conditions. 2.7. Consequential amendments to the applicable Aerosol Group Standards will be required to update the reference to the Conditions. 1 http://www.epa.govt.nz/hazardous-substances/approvals/group-standards/Pages/site-storage.aspx 3|Page Proposed Amendments to the Site and Storage Conditions for Aerosols 3. The Proposed Amendments 3.1. The proposed amendments are to Part 2, Clauses 21 and 22; Part 3, Clause 25; and the interpretation section at the end of the Conditions. Proposal 1 – Delete Part 2 3.2. It is proposed to delete Part 2 “Flammable aerosols NOT located at a hazardous substance location” from the Conditions. Part 2 ‘Conditions relating to the Unintended Ignition of Flammable Aerosols not located at a hazardous substance location’ IS DELETED. 3.3. Part 2 has no material effect because the aggregate quantity triggering the separation control is also the trigger quantity for the requirement to have a hazardous substance location. 3.4. Part 3, Clause 25 Separation of building holding flammable aerosols from boundary of controlled zone provides the following: 25(1) This clause applies to a building that holds flammable aerosols at a hazardous substance location, the capacity of which exceeds 3000 L aggregate water capacity. 25(2) If the controlled zone containing a building to which this clause applies abuts an area of high intensity land use, the building must be separated from the boundary of the controlled zone by not less than 3m. 3.5. The proposed amendments to Clause 25 add alternative requirements for the storage of flammable aerosols presented as: 3.5.1. Holding: 3.5.1.1. more than 3000 litres up to 10,000 litres aggregate water capacity; and 3.5.1.2. more than 10,000 litres aggregate water capacity, in either: 3.5.1.3. A dedicated building or room holding aerosols only, or in 3.5.1.4. A general purpose warehouse. 4|Page Proposed Amendments to the Site and Storage Conditions for Aerosols Proposal 2 – to allow for alternative requirements Amend clause 25(2) “25(2) If the controlled zone containing a building to which this clause applies abuts an area of high intensity land use, the building must be separated from the boundary of the controlled zone by not less than 3m; OR 3.6. This amendment is required in order to allow alternative solutions to follow. Proposal 3 – Dedicated building or room in a building New clause 25(3) The building or room may have less than 3 metres separation and abut the boundary of the controlled zone if: a. The building / room holds up to 10,000 litres aggregate water capacity of flammable aerosols and either the building / room has fire rated walls of FRR 60/60/60, and selfclosing fire rated doors of FRR -/60/60; or the building / room has sprinklers delivering water as per section 6.3.2 and associated tables in NFPA 30B and designed and maintained in accordance with NZS4541: 2007; or b. The building /room holds more than 10,000 litres aggregate water capacity of flammable aerosols, and either i. the building /room has fire rated walls of FRR 120/120/120, self-closing fire rated doors of FRR -/120/60, and either a. fire rated parapet walls of FRR 120/120/120 or b.fire rated ceiling panels of FRR -/120/120 extending back into the room by 2.4m from the wall abutting the boundary with high intensity land use; or ii. the building / room has fire rated walls of FRR 60/60/60, self-closing fire rated doors of FRR -/60/60, and either a. fire rated parapet walls of FRR 60/60/60 or b.fire rated ceiling panels of FRR -/60/60 extending back into the room by 2.4m from the wall abutting the boundary with high intensity land use AND c. the building / room has sprinklers delivering water as per section 6.3.2 and associated tables in NFPA 30B and designed and maintained in accordance with NZS4541: 2007. 5|Page Proposed Amendments to the Site and Storage Conditions for Aerosols Revised clause 25(1) 25(1) This clause applies to a building or room that holds flammable aerosols at a hazardous substance location, the capacity of which exceeds 3000 L aggregate water capacity. 3.7. These cases allow storage of aerosols in a dedicated building to have reduced separation down to zero separation or to allow storage in a dedicated room in a building, provided the building or room has fire rated construction of walls, doors and ceiling areas adjacent to the high intensity land use depending on the quantity of aerosols held. A combination of fire rated construction and fire protection is also provided. 3.8. A consequential amendment is made to 25(1) to allow for the addition of the case of storage in a room in a building. Proposal 4 – Aerosols in a general purpose warehouse New clause 25(4) Where there is an aggregate quantity of flammable aerosols greater than 3,000 litres water capacity but less than 10,000 litres water capacity held in a general purpose warehouse used for receiving, storing and distributing of mixed goods and not accessible by the general public, instead of 3 metres separation to the boundary of the controlled zone, the flammable aerosols may be held in an area separated from the rest of the warehouse by either: a. Interior fire rated walls of FRR 60/60/60 from floor to roof and self-closing fire rated doors of FRR -/60/60, or b. chain-link fencing from floor to roof of 2.9mm or 9 gauge steel wire with a maximum 50mm diamond mesh, with self closing gates or labyrinth openings of overlapping chain link fencing, and an in-rack sprinkler system delivering water as per NFPA 30B and designed and maintained in accordance with NZS4541: 2007. OR Where there is a capacity of flammable aerosols greater than 10,000 litres aggregate water capacity held in a general purpose warehouse used for receiving, storing and distributing of mixed goods and not accessible by the general public, instead of 3 metres separation to the boundary of the controlled zone, the flammable aerosols may be held in a segregated area separated from the rest of the warehouse by either: a. interior fire rated walls of FRR 120/120/120 from floor to roof and self-closing fire rated doors of FRR -/120/60, or 6|Page Proposed Amendments to the Site and Storage Conditions for Aerosols b. chain-link fencing from floor to roof of 2.9mm or 9 gauge steel wire with a maximum 50mm diamond mesh, with self closing gates or labyrinth openings of overlapping chain link fencing, and an in-rack sprinkler system delivering water as per section 6.3.2 and associated tables in NFPA 30B and designed and maintained in accordance with NZS4541: 2007 3.9. These cases allow for alternatives to the 3 metres separation where aerosols are stored in a general purpose warehouse to which the public do not have access. That is, this does not apply to retail establishments. Proposal 5 – Define fire resistance rating Fire resistance rating (FRR), in relation to an object or item, means that the object or item is able to maintain its stability, insulation, and integrity, and is able to offer protection against heat radiation for the time specified by the relevant rating in minutes, where stability, insulation, and integrity, respectively, have the meanings ascribed to them in clause A2 of Schedule 1 of the Building Regulations 1992. 3.10. This definition taken from the Hazardous Substances (Classes 1 to 5 Controls) Regulations is required as the amendments introduce fire rated buildings and doors. Proposal 6 – Incorporate correct definition of ‘area of high intensity land use’ area of high intensity land use— (a) includes— (i) an area of regular habitation; and (ii) a structure made of or containing combustible materials that would sustain a significant fire; and (iii) a high density traffic route; but (b) does not include a small office constructed of non-combustible materials associated with a hazardous substance location that is used by persons authorised to be at the location by the person in charge of that location 7|Page Proposed Amendments to the Site and Storage Conditions for Aerosols 3.11. This definition was corrected in November 2006 to follow Schedule 10 of the Transfer Notice which is the applicable definition for managing the effects of unintended ignition. It can now be formally incorporated. Proposal 7 – Define standards referenced in the proposals NFPA refers to documents published by the National Fire Protection Association, Quincy, Massachusetts, USA and NFPA 30B refers to the standard “Code for the manufacture and storage of aerosols” 2007. NZS refers to a New Zealand Standard published by Standards New Zealand and NZS4541 refers to the standard “Automatic fire sprinkler systems” 2007. 3.12. These definitions are to be added to the Interpretation section to clarify the standards that are incorporated by reference into the Conditions. 8|Page Proposed Amendments to the Site and Storage Conditions for Aerosols 4. The EPA’s assessment 4.1. Before amending a group standard, the EPA must: a. be satisfied that the group standard is a more efficient and effective way of managing the risks of all the substances in the group; b. be satisfied that all the substances or products in the group standard have a similar nature, are of a similar type, or have a similar circumstance of use, such that the risks of the substances or products can be effectively managed by one set of conditions; c. consider best international practices and standards for the safe management of hazardous substances; and d. consider the types of controls appropriate for the group in accordance with sections 77, 77A and 77B of the HSNO Act. 4.2. The EPA’s assessment of these matters follows. Efficiency and Effectiveness 4.3. The EPA considers the group standards for aerosols remain a more efficient and effective instrument for managing the risks associated with all the hazardous substances in this group. It allows importers and manufacturers to determine whether or not their products comply with the group standard, and what they must do to achieve compliance. The amendment of the Conditions has no effect on the efficiency and effectiveness of the group standards themselves. One Set of Conditions for Similar Nature, Type, or Circumstance of Use 4.4. The flammable aerosols covered by the identified group standards are of a similar nature, type or use such that they were appropriate for inclusion in the Aerosols Group Standards at the time the group standards were first issued in 2006. This proposed amendment has no effect on the scope of the substances covered by these group standards. Best International Practices and Standards 4.5. The EPA has considered standards established in other jurisdictions for the purposes of managing the risks associated with aerosol storage and is of the view that the proposed amendments reflect best international practice for managing the risks of the unintended ignition of flammable aerosols. 4.6. The standards used (AS/NZS3833: 2007 and NFPA 30B: 2007) to identify equivalent solutions to the 3 metre separation distance reflect best international practice. In section 6.3.5, NFPA 30B specially addresses the case of segregated aerosol product storage in general purpose warehouses and has been used by the EPA for considering equivalent solutions in the past. AS/NZS3833: 2007 is generally applicable referring to ‘retail distribution centres’ and provides direction in the levels of fire rating for buildings and rooms ‘storing dangerous goods in retail packages’. 9|Page Proposed Amendments to the Site and Storage Conditions for Aerosols Controls appropriate for the group in accordance with sections 77, 77A and 77B of the HSNO Act 4.7. The amendments in the Conditions provide alternative requirements to the 3 metre separation distance that manage the adverse effects of the storage of flammable aerosols in class 2.1.2A in accordance with section 77 of the HSNO Act. 4.8. The amendments are proposed in line with section 77A(3)(b) to vary the specified 3 metre separation distance. 5. The Next Steps Consultation 5.1.
