EXTRACT: AS 1596-2008 Section 2: LPG Minor Storage & Usage
The underlying concept of minor storage is that quantities below a certain level are generally unlikely to play a significant part in spreading a fire from place to place. The firefighting services and facilities required under normal building regulations are expected to cope adequately, provided that—
(a) the quantity of LP Gas does not exceed that given in Table 2.1; (b) the storage conditions comply with Clause 2.3; and
(c) the use of LP Gas is an accordance with AS 5601/NZS 5261 or other relevant standard.
1 For greater quantities of LP Gas, Section 4 applies.
2 Workplace safety regulations and guidelines may apply even to quantities defined as minor storage in this Standard.
2.2 APPLICATION OF SECTION
Cylinders of LP Gas in quantities not exceeding those given in Table 2.1 and complying with this Section (Section 2) may be classified as minor storage. In such cases, the requirements of this Section shall apply.
Where greater quantities of LP Gas are stored and handled, or the conditions set out in this
Section cannot be met, other relevant sections of this Standard shall apply.
NOTE: Approximate volumes (water capacities) of LP Gas cylinders and the nominal masses of
LP Gas contained therein are given in Appendix C.
This section does not apply to—
(a) cylinders used for decanting purposes; or
(b) in-situ fill cylinders.
2.3 MINOR STORAGE AND USAGE OF LP GAS
The following requirements and recommendations apply to the minor storage and usage of
(a) The use and storage of cylinders of LP Gas indoors, whether full or nominally empty, should be avoided wherever practicable. Cylinders should preferably be located out- of-doors.
NOTE: Figure 2.1 shows examples of outdoor areas allowed by this Section.
(b) The total quantity of LP Gas kept (both in storage and connected for use) shall not exceed that stated in Table 2.1. This quantity includes LP Gas cylinders and non- refillable containers in use, whether full or nominally empty, but not those cylinders installed outdoors in accordance with Section 4 of this Standard and AS 5601/NZS 5261.
(c) Any cylinders in use shall be connected to an approved appliance and used in accordance with AS 5601/NZS 5261 or other applicable Standard.
(d) Users of LP Gas should be aware of the hazards and risks of its storage and use.
(e) Cylinders shall be kept upright in a well-ventilated area away from any flame, heat or other ignition sources.
(f) Cylinders shall be protected from excessive temperature rise. (g) Cylinders shall be kept upright at all times.
(h) Cylinders shall be protected from physical impact.
(i) Cylinders shall be located so that they are not likely to be damaged or dislodged under normal circumstances of use. Any trolley or stand in which the cylinder is housed shall be of metal construction and of adequate stability.
(j) Cylinders shall be kept in a location that does not hinder the escape of people, and is away from any combustible or waste materials.
(k) Cylinders shall be kept at least 3 m from oxidizing gases, except where the cylinders of LP Gas and oxidizing gas form part of a portable oxy-fuel system used for welding, brazing, cutting and the like.
NOTE: Reference should be made to AS 4839 for portable and mobile oxy-fuel gas systems.
(l) Cylinders shall be stored with all cylinder valves closed when not in use.
(m) Cylinders and their fittings shall be inspected for leaks prior to their use, e.g. by using a soap and water or detergent solution to detect leaks at all joints.
CAUTION: THE AMMONIA PRESENT IN SOME SOAPS AND DETERGENTS CAN REACT WITH BRASS FITTINGS AND CAUSE SUCH FITTINGS TO CRACK AFTER A SHORT PERIOD OF TIME. CAUTION SHOULD THEREFORE BE EXERCISED WHEN USING SOAP SOLUTIONS ON BRASS FITTINGS, AND ALL CONNECTION SHOULD BE RINSED THOROUGHLY WITH FRESH WATER AS SOON AS POSSIBLE AFTER THE APPLICATION OF THE SOAP SOLUTION.
2.4 GROUPS OF TEMPORARY STRUCTURES IN WHICH LP GAS IS USED
Where temporary structures are grouped together, e.g. a group of marquees, stalls or tents at a market, there shall be a maximum of 10 such structures using LP Gas in any such group.
Groups of temporary structures using LP Gas shall be separated by at least 15 m. The intervening space may be occupied by temporary structures in which no flammable gas or flammable liquids are kept.
