Provides requirements and recommendations for the design, construction and operation of installations where flammable or combustible liquids are stored and handled. Separate sections provide requirements for minor storage, package storage, and storage of liquids in tanks, as well as, fire protection and emergency management. Requirements for the bulk storage of potable alcohols, and recommendations for blending plants, are provided in appendices.
This Standard sets out requirements and recommendations for the safe storage and handling of flammable liquids of dangerous goods Class 3, as classified in the UN Recommendations for the Transport of Dangerous Goods—Model Regulations and listed in the ADG Code. This Standard also provides requirements and recommendations for the storage and handling of combustible liquids, as defined in Clause 1.4.9.
This Standard provides minimum acceptable safety requirements for storage facilities, operating procedures, emergency planning and fire protection. It provides technical guidance that may assist in the storage and handling of flammable and combustible liquids in accordance with the risk management requirements of NOHSC:1015 and legislation which draws on that document.
This Standard provides requirements for commonly used flammable and combustible liquids such as hydrocarbons and industrial solvents. Some flammable and combustible liquids have other physical and chemical properties that require additional precautions and design considerations. Examples of these are—
(a) liquids that can polymerize;
(b) liquids that require blanketing with inert gas;
(c) liquids that are heated; and
(d) liquids that are assigned a subsidiary risk.
Any special precautions and considerations necessary for the safe storage and handling of such liquids are additional to the requirements and recommendations provided in this Standard.
For the storage and handling of dangerous goods of another class but having a Class 3 subsidiary risk, this Standard is relevant to their flammability aspects.
Where this Standard applies
This Standard applies to the storage and handling of Class 3 dangerous goods as described and listed in the ADG Code, with the exception of desensitized explosives of Class 3. It also applies to the storage and handling of combustible liquids. The requirements of this Standard apply in conjunction with, but do not take precedence over, any government regulations that apply in any area.
NOTE: Further information on the classification of flammable liquids, based on the 6th edition of the ADG Code, is given in Appendix A.
Where the flammable liquid being kept has one or more Subsidiary Risks, reference shall be made to the Australian Standards relevant to the classes of those risks and the more stringent requirements shall apply. Where any combustible liquid being kept has risks of other Classes, the relevant Australian Standard for that Class shall be consulted, but for requirements relating to its combustible properties and fire safety, this Standard shall apply.
NOTE: As there is no legal requirement to label combustible liquids as such, it is often difficult to ascertain whether liquid in a drum or other package is a C1 or C2 combustible liquid. Only rarely do material safety data sheets (MSDS) indicate that a liquid is combustible. The actual classification can be determined by reference to the flash point (see Clause 1.4.29). If the flash point is not provided on the MSDS, it should be ascertained from the manufacturer or Australian supplier of the liquid.
This Standard applies in locations that are generally industrial, commercial or rural in nature, including laboratories where the provisions of this Standard are additional to those of AS 2243.10.
Where this Standard does not apply
This Standard does not apply to the following:
(a) The transport of flammable liquids, which is covered by other regulations, rules and codes, e.g. the ADG Code, the International Maritime Dangerous Goods (IMDG) Code.
(b) The handling of flammable liquids in port areas, where covered by AS 3846.
(c) Shipboard installations.
(d) The storage and handling of potable spirits having less than 24% v/v ethanol, and in inner packagings of not more than 5 L capacity.
(e) Residential-type heating oil installations comprising Category 1 tanks.
NOTE: Tank categories are described in Clause 1.4.7.
(f) Liquefied gases that are maintained in the liquid phase for storage by means of pressure or refrigeration.
(g) Fuel tanks of any mobile vehicle or equipment, including those on large mining vehicles.
(h) Temporary field storages and associated facilities in remote locations for Australian Defence Force exercises or operations, or declared states of emergency.
