Sets out specifications for the siting, design and layout of timber preservation plants, and improved practice options for existing plants, in order to promote their safe operation and reduce environmental and occupational hazards. It incorporates information on the contents of The Australian environmental guidelines for copper chrome arsenate timber preservation plants, which was prepared by Australian and New Zealand Environment and Conservation Council (ANZECC) and The Timber Preservers Association of Australia (TPAA). Appendices provide lists of some regulatory authorities currently involved in some aspects of timber preservation and an example of a compliance timetable for the assessment and management of contaminated sites.

This Standard specifies requirements for the siting, design and layout of timber preservation plants (hereinafter referred to as plant(s)). It deals in general terms with these aspects in a manner intended to reduce the occupational health risk to plant operators and to lower the potential for environmental pollution.
