AS/NZS 3666 Part 1 - Legionella Control Australia

Air-Handling and Water Systems of Buildings - Microbial Control - Design, Installation and Commissioning

AS/NZS 3666 Part 1 - The Australian Standard/New Zealand Standard AS/NZS 3666 Part 1 is concerned with microbial control issues associated with air handling and water systems in commercial buildings.

AS/NZS 3666 Part 1 identifies the minimum requirements for the design, installation and commissioning of such building systems.

Although originally developed for commercial building services systems AS/NZS 3666 Part 1 can also be applied to other commercial or industrial air handling and water systems, and to domestic systems incorporating cooling water equipment.

Common Sources of Legionnaires' Disease

This standard looks at common sources of Legionnaires’ disease in commercial building air handling and water systems.

Other sources, both known and potential, include cooling water systems for refrigeration equipment and air compressors, industrial heat exchangers when opened for cleaning, decorative fountains, spray irrigation systems, and industrial water-based cutting fluid systems.

Whilst AS/NZS 3666 Part 1 identifies minimum design, installation and commissioning requirements associated with the control of microbial growth in air handling and water systems of commercial buildings; operational and maintenance issues are dealt with in AS/NZS 3666 Part 2.

For additional information concerning the control of microbial growth in air handling and water systems of commercial buildings, HB 32 should be consulted.
