WATER STORED PRESSURE FIRE EXTINGUISHERS

They are most suitable to extinguishing flammable liquids containing materials such as petrol, diesel, solvents and fats like grease and oils. Mechanical foam type fire extinguishers are useful for paints, lubricants, chemical industry, oil fire/refinery, kitchen/restaurant, boiler room, etc.A stored pressure extinguisher has the agent and pressure mixed in the same container inside of the extinguisher. A cartridge-operated extinguisher has just powder/agent inside, and there is a separate pressure cartridge that has to be activated to pressurize the extinguisher.
