HAZARDOUS AREAS
(Νormative)
The hazardous areas illustrated in Figures E1 are taken from AS/ΝZS 60079.10.1. The examples provided are not complete and other situations and requirements that may be relevant to LP Gas installations are also provided in AS/ΝZS 60079.10.1. Hazardous Areas:
Make sure that sources of ignition are outside the zone as shown in the above diagram. Sources of ignition include
A source of energy sufficient to ignite an explosive atmosphere.
NOTΕ: Εxamples of ignition sources include naked flames, exposed incandescent material, electrical welding arcs, mechanical or static sparks, and electrical, electronic or mechanical equipment not suitable for use in hazardous locations.

EXCHANGE CYLINDER LOCATION
DISTANCES FROM OPENINGS

* This distance is measured from the top of any cylinder valve

Cylinders shall be install in accordance with the following requirements

  • Cylinders shall be installed on a firm, level, non- combustible base, not resting on soil. The floor or base shall be constructed so that water cannot accumulate within any enclosure or recess.
  • Any cylinder shall be restrained to prevent failing
  • A cylinder shall be installed so that the pressure- relief valve is in contact with the vapour space and any discharge from this valve is directed away from any adjacent cylinders or combustible structures
  • A cylinder intended to be exchanged or removable shall be connected to a fixed piping system.
  • Where 2 or more exchange cylinders are connected for use, a means shall be provided to permit the cylinder to be isolated from the gas supply, to allow the cylinders to be disconnected either by a manual or automatic changeover valve shall be installed immediately upstream of the regulator serving the system.
Regulator
  • Must be fixed rigidly to an adequate support that is independent of the cylinders and mounted with the diaphragm vertical and the vent pointing vertically downwards
