Provides guidance on the classification of areas associated with vehicle workshops, vehicle parking areas, fuel dispensing stations and aircraft hangars. It includes specific examples of classification for the aforementioned areas as well as for residential garages and pollution control equipment. To be read in conjunction with AS/NZS 2430.3.1:1997.

This Standard provides examples of area classification for areas associated with vehicle workshops, vehicle parking, fuel dispensing stations and aircraft hangars. The Standard is part of the AS/NZS 2430.3 series, which recommends the classification of several commonly occurring situations, and should be read in conjunction with AS/NZS 2430.3.1.
