Definitions

  • the object of the present specification is a cartridge-operated fire extinguisher, which will make it possible to extinguish fires by sublimation of a pyrotechnic compound and the discharge of the resulting gases with the capacity to significantly displace oxygen following activation in the manually operated device.
  • class A fires involve ordinary combustible materials such as wood, cardboard, paper and fabrics, etc.
  • class B fires involve flammable and combustible liquids such as such as petrol, alcohol, waxes and greases, etc.
  • class C fires involve gaseous fuels such as butane, natural gas, propane and methane, etc.
  • the solution proposed herein would be a class-B fire extinguisher, a category which includes all high-pressure CO2 extinguishers, such as those usually found in public and residential spaces such as hospitals, universities, apartment blocks, etc.
  • CO2 extinguishers such as those usually found in public and residential spaces such as hospitals, universities, apartment blocks, etc.
  • these extinguishers usually generate a quantity of extinguishing gases that in no case exceeds 200 times the volume of the container, as well as the production of carbon-dioxide snow, ice crystals or moisture due to condensation.
  • the cartridge-operated extinguisher comprises a compacted pyrotechnic composition that generates extinguishing gases inside the cartridge, which corresponds, in turn, to a container with a seal to prevent gases from escaping in its upper part and a compound-initiation system in its base.
  • the cartridge-operated fire extinguisher can be used by manually operated actuating mechanisms designed for this purpose.
  • the fact that it can be easily used by any user means that small fires can be put out more quickly or even instantly, as it generates a jet of extinguishing gases with a duration determined by the size and volume of the cartridge selected, since it can be used to put out the fire as soon as it breaks out, even in the outbreak phase, preventing it from spreading at the crucial moment when it is easiest to extinguish, and not once it has already had time to spread.
  • the container and throttle valve are both made of high-temperature resistant materials.
  • the extinguishing cartridge is designed for extinguishing fires, it could ideally also be used for other purposes such as detecting leaks in ducts or creating a smoke signal, among others.
  • the extinguishing cartridge comprises a compacted pyrotechnic composition that generates extinguishing gases (2) inside a high-temperature-resistant container (3) which, in turn, comprises a closure (4) made from high-temperature-resistant materials to restrict the discharge of gases in its upper part and a pyrotechnic-activation system, either by percussion or pyroelectric ignition, (5) in its base.
  • a high-temperature-resistant material is any metallic material.
  • the container is between 120 and 140 millimetres long and between 20 and 50 millimetres in diameter.
  • the compacted pyrotechnic composition that generates extinguishing gases weighs between 40 and 70 grams and discharges for a maximum of 4 seconds after the cartridge is activated.
  • the cartridge-operated fire extinguisher is designed to be initiated by percussion or pyroelectric ignition, resulting in the ignition of the cartridge and the directional discharge of a jet of white and/or greyish extinguishing gases.
  • the extinguishing cartridge In terms of use, the extinguishing cartridge must be kept in its container until it is to be used, when the cartridge shall be placed in the receptacle of the actuating mechanism. Upon activation, the actuating mechanism must be held firmly with both hands and pointed in the direction in which the extinguishing gases are to be discharged. The cartridge shall then be discharged from the actuating mechanism, with as many cartridges as required to put out the fire, used one after the other.
