Fire and Explosion Countermeasures In Confined Spaces

This includes fixed structures such as defence buildings, bunkers, aircraft shelters, command posts and ammunition depots, as well as the critical components of weapon platforms such as submarines (battery and engine rooms), ships (engine room), tanks and other armoured personnel carriers (ammunition storage and engine compartments).

Competitive advantage

  • Our approach is based on the use of ultra-fast water mist/liquid nitrogen suppression systems, utilising the synergies between the two working fluids
  • The system is compact and lightweight
  • The system causes minimal damage (if any) when deployed due to its rapid flame quenching and inerting effects, which require small quantities of water and/or liquid nitrogen

Successful applications of research

Design and implementation of a range of new fire and explosion countermeasures against:

  • Jet fires in battery rooms (in submarines and ships)
  • Pool fires in engine rooms (in submarines, ships, tanks and armoured personnel carriers)
  • Deflagration/detonation in ammunition storage compartments (in tanks, ships and submarines)

Partners

  • Defence Science and Technology's Maritime Division
  • Victoria University

Impact

  • The outcomes of this research will enable the Australian Defence Force to protect their assets against fires and explosions more effectively
