EXPANSION FOAM FIRE EXTINGUISHING SYSTEM
|
|
 |
LOW EXPANSION FOAM Low expansion foam extinguishing systems make use of the smothering and cooling effects to extinguish fire which are secured by foam layer covering the burning surface and shutting off air supply to the seat of fire. The systems are particularly suited for oil fires. Chiefly used as an extinguishing system for the cargo tank and process decks of tanker and as an additional installation to other extinguishing systems in the machinery space with automatic release devices.
HIGH EXPANSION FOAM High expansion foam extinguishing systems the fire through cooling, suffocation and inert gas from the foam. The System consists of foam concentrate with its storage tank, fire water pump, foam supply & mixing unit, piping, foam generators and control devices. The foam concentrate is multi purpose foam with 2% mixture for high expansion. The foam premix solution does not resist polar solvents, however, fires with most of polar solvents can be extinguished by the high expansion system. The quality of the foam depends on the fire scenario, burning material, type of smoke, and temperature, etc. |
