Introduction to Water Mist Fire Detection Fighting System. Automatic sprinkler systems - sprinkler & water-sprayingsystems required by SOLAS Regulations II-2/10.4, 10.5 and 10.6. High Pressure Water Mist System(Hyper Mist) is for using in machinery spaces of category A (ME. AE, Purifier, Boiler etc.) It is therefore not possible to design a mist system simply by reference to one of the standards available – unlike sprinkler systems where, for example, reference to BS EN 12845 or BS 9251 enables a full design to be produced and a fully compliant system to be installed. The rapid decrease of the oxygen concentration for the high-pressure system was owing to the migration of smoke from the upper part of the room caused by the strong mixing flow. Drain and test valves must be closed and well marked. CONCLUSION The hyper mist or high pressure fog fire fighting system is installed for all important ship’s machinery systems in the engine room (ME. However, for all the fire sizes, the amount of energy absorbed by the mist was between 30-70 percent of that theoretically released by the fire. However, it can be run as Manual mode too by turning the selector switch from Auto to Manual mode.
