Specifies requirements for the design, construction and testing of spray painting booths, designated spray painting areas and paint mixing rooms in which there may be an explosion hazard due to the presence of flammable volatiles from the paints and finishes used. It is intended to be read in conjunction with AS 2381.1.

This Standard specifies requirements for the design, construction, and testing of spray painting booths, designated spray painting areas and paint mixing rooms, in which flammable liquids are used. It also covers booths incorporating baking or heating cycles, using either direct or indirect heating systems. For booths using direct fired heating systems, only those using fuels covered in Australian Standards, and in New Zealand, by the New Zealand Standards for gas installations referenced in the New Zealand Gas Regulations, are covered by this Standard. The requirements contained in this Standard are supplementary to the requirements for electrical apparatus specified in AS/NZS 3000, Wiring Rules and the relevant requirements of the AS/NZS 2381 series. NOTES: 1 Attention is drawn to other requirements that may be contained in the respective legislation. 2 Part 2 of this Standard details requirements for the installation and maintenance of spray painting booths, designated spray painting areas and paint mixing rooms. 3 Water-based paints contain flammable liquids in the form of organic solvents. This Standard applies to all types of paints containing flammable liquids including water-based paints, since they also contain organic solvents. This Standard does not apply to (a) dry powder type spray booths or operations, the requirements for which are detailed in AS 3754; or (b) ovens used for the sole purpose of drying or baking.
