- The new fire extinguishing agent(Novec 1230) has been developed as an alternative to Halon system of which production had already been ceased at the end of 1993, under the agreed regulations made at the Montreal Protocol in November 1992.
It is known that the new agent contains no Bromine(Br) or Chlorine(Cl) and has an Ozone Depleting Potential of zero. This new agent system utilizes one or more storage containers arranged to provide the protected area with a pre-determined quantity of gases.
The reasons why many industries are interested in the new fire extinguishing agent(Novec 1230) can be explained by Ozone Depletion Potential(ODP) and Global Warming Potential(GWP).
It is said that the fire extinguishing agent rapidly extinguishes fire through a combination of heat absorption(main action) and an element of chemical reactions with the flame.
This new fire extinguishing agent is considered as safe for people with large safety margin without environmental pollution. Recently, this has been introduced as fire extinguishing agent for ship's electric spaces and also total flooding fire extinguishing system for engine room.
In this study, practical and empirical guidelines are constructed for further usages of the new fire extinguishing agent following the standard guidelines of the manufacturer. As the practical installation of the new agent system on board, the fire fighting system of the Qatar LNG carrier was tested as a benchmark.
It has been found that the application of new fire extinguishing agent is very similar to Halon systems in general. But, following main design criteria should be considered before actual and detail design of the new fire extinguishing agent.
-Room integrity should be based on the concept of the gas tight door and ¨A-0〃 steel bulkhead.
-Damper control of ventilation to each protected space should be considered to have separate air tight concept.
-Modular design or banked design should be selected for the actual design of machinery room layout.
