AS 5414-2012

Abstract

Specifies general requirements for the design, installation and maintenance of water spray systems intended to provide a degree of building protection against bushfire exposure, including ember attack, together with limited protection against radiant heat exposure (up to 19 kW/m2 (BAL19).

Scope

This Standard sets out general requirements for the design, installation and maintenance of
water spray systems intended to provide a degree of building protection against bushfire
exposure, including ember attack, together with limited protection against radiant heat
exposure [up to 19 kW/m2(BAL 19)]. Bushfire water spray systems are intended to
complement the requirements of AS 3959, and should be considered as one component of a
holistic fire management plan.
NOTE: For further guidance see Appendix B of this Standard and the site assessment aspects of
AS 3959.
It is recognized that installation of a bushfire water spray system is to be preceded by some
form of on-site evaluation by a qualified bushfire assessment practitioner. In such cases it is
recommended that the practitioner witness the system commissioning test and countersign
the completion certificate.
NOTE: Where required, a copy of the completion certificate should be forwarded to the local
government authority and the fire service concerned.
Bushfire water spray systems may be used for protection against bushfire ember attack on
BCA Class 1a, 1b, 2, 3 and 9c buildings, particularly existing buildings which are not fully
compliant with the requirements of AS 3959.
