    Abstract - (Show below) - (Hide below)

    Provides guidance on the classification of several commonly occurring situations in which flammable liquids or gases are generated, processed, handled or stored and which are therefore potentially hazardous.

    Scope - (Show below) - (Hide below)

    This Standard classifies specific hazardous areas. It covers several commonly occurring situations where the degree of hazard has been determined and the relevant authorities have agreed on the classifications to be used.The classifications given in this Standard may not apply to specific occupancies where (a) the quantity of release is either very large or very small;(b) the design of a particular plant does not comply with the appropriate Australian Standards; or(c) ventilation, use of inert gases, vapour barriers or other methods are used to reduce the extent or degree of risk of a particular hazardous area.In such situations, reference should be made to AS 2430.1.
