Overview

Water mist suppression systems are an established and approved technology in many high-risk and/or special hazard applications are increasing in popularity for overseas road tunnels. This presentation will discuss differences between water mist and deluge and consider implementation and interaction with other systems and structural design.

Water deluge systems have remained the established means of automatic fire suppression within Australian road tunnels for over 30 years. Whilst effective in protection of life and preservation of tunnels in a fire, there are compromises; the cost and scale of the systems, the burden imposed on the tunnel drainage systems, and potential impact on occupants and responding emergency personnel, to name a few. Water mist suppression systems are an established and approved technology in many high-risk / special hazard applications.

As an alternative in road tunnels, water mist suppression systems address many of the issues inherent with deluge, whilst achieving similar outcomes. Much less water is used, which impacts cost and space associated with both suppression and drainage. For these reasons and many more, water mist suppression systems are increasing in popularity in overseas road tunnels. Hurdles to local implementation are varied, and include lack of familiarity/local precedents, potential interactions with smoke ventilation systems, and potential considerations for time-temperature curves and therefore structural design. Our speakers will aim to shed light on the varied aspects of this technology, and the pathway to it’s effective implementation in Australian road tunnels.
