Definitions

  • This invention relates to a fire extinguisher which automatically ejects a fire extinguishing material there from, and more particularly to a fire extinguishing material which may prevent the spread of the fire and provide a barrier when a fire occurs by automatically ejecting fire extinguishing material in every direction.
  • a fire extinguisher comprising a container that is so designed as to be broken into pieces, when exposed to heat at a given temperature below 100°C, whereby the container is broken due to the heat produced at the initial stage of the fire, under an increased internal pressure therein, so a fire extinguishing material in the container may be scattered around in every direction for extinguishing the fire.
  • a fire extinguishing material in which three ingredients such as disodium hydrogen phosphate, sodium sulfate and sodium bicarbonate are included and prior art ingredients such as ammonium sulfide and ammonium chloride are replaced by ammonium carbonate, so that there are produced gases which are not harmful to persons involved in the fire fighting and animals therearound and which do not stain clothes of these persons.
  • a fire extinguisher which may be suspended in a space, wherein the fire is anticipated, and which includes a metallic container having mary holes in its bottom wall. These holes are closed with plugs of two or more kinds, the plugs of one kind having a relatively low melting point or fire point, and plugs of another kind having a relatively high melting point or fire point, whereby fire extinguishing material in the container is ejected through those holes closed by the plugs having a relatively low melting point when such plugs melt, to extinguish the fire in an initial stage, and the fire extinguishing material is ejected through those holes closed by the plugs having a relatively high melting point or fire point when such plugs melt, to extinguish flames having a strong force.
  • the plugs are melted due to the heat of the fire and blown off due to internal pressure build-up in the container.
  • a fire extinguishing material as used in the present invention preferably contains, in weight percent, the following ingredients:
  • ammonium carbonate in the fire extinguishing material decomposes, when heated to a temperature of 60° to 200°C as follows:-
  • the above fire extinguishing material is packed in a container which is adapted to be broken into pieces when heated at a given temperature below 100°C.
  • CO 2 and NH 3 gases are produced according to the equations (I) to (IV), thus increasing an internal pressure in the container.
  • the internal pressure is also increased as the water vapor pressure increases, thus increasing the volume of the container to break same into pieces.
  • the fire extinguishing material is scattered in every direction. CO 2 and NH 3 gases thus participate in fire extinguishing, while the water glass and burnt alum produced alumina silicate base compounds which give the desired viscosity.
  • the alumina silicate compound gives a fire-protective film to cover unburnt substances over a wide area and protect same against catching fire.
  • a covering function of viscous chemicals, and the fire extinguishing and fire-protective functions of C0 2 and NH 3 gases may be achieved at the same time.
  • the fire extinguisher comprises a tempered glass container 1 which is adapted to be broken into pieces, instantaneously when heated to a given temperature below 100°C.
  • the container 1 is cylindrical and of circular cross-section although any desired shape may be employed.
  • a fire extinguishing material 2 is sealed in the container 1.
  • Caps 4 and 5 are fitted on axially opposite end portions of the container 1, with spaces left between inner ends of the caps and the ends of the container, in which spaces cushioning pads 3 are provided. Mushroom-shaped projections 6 and 7 are provided at the axially opposite external ends of the caps 4 and 5.
  • the U-shaped member 10 is further provided with grooves 11 and 12, in the limbs thereof, the grooves 11 and 12 open onto side edges of the limbs.
  • the projections 6 and 7 are engaged in the grooves 11 and 12 so that the container 1 can be detachably supported by the member 10 in a horizontal position spaced from the wall 14 (Fig. 3B) or from the ceiling (3A). In either case, the grooves 11 and 12 slant upwardly towards the openings thereof.
  • the fire extinguisher can be thus mounted in a room in which there is . a risk of a fire starting .
  • the container 1 is heated by the flames until it is automatically broken or may be manually thrown by hand at the fire source
  • the fire extinguishing material 2 is scattered in all direction to extinguish the fire in the manner des cribed eachier
  • the fire extinguisher comprises a container 1', which is of rectangular box shape although it may be of any shape such as rectangular, square, circular cross-section.
  • the fire extinguishing material 2 is packed in the container 1' which may be suspended from a ceiling 18 as by supports 17 as shown in Fig. 4 or may be directly secured thereto.
  • the container 1' may be made of brass, steel or stainless steel for example.
  • Provided in the undersurface of the container 1' are a suitable number of holes 15 of-any suitable size. These holes 15 are plugged with plugs 16 of at least two kinds having melting points or fire points of 60° to 200 o C.
  • each hole 15 is provided with a stepped cylindrical wall of circular cross-section rather than being formed merely by punching the material of the container 1!
  • the walls may project either outwardly (as shown in Fig.5) or inwardly of the bottom surface and/or the sides of the container 1' by 0.5 to 5mm.
  • Materials which may be used for the plugs 16 are sulfur (melting point, 114°C), guttapercha (melting point, 6 0 ° to 70°C), Wood t s metal (melting point, 73°C), Rose's metal (melting point, 110°C) and tin (melting point, 200°C) i.e., a material having a melting point or fire point ranging from 60° to 200°C.
  • the holes 15 are plugged with the plugs 16 made of suitable material having regard to the positioning and diameters of the holes 15 being taken into consideration.
  • the plugs 16 are melted or burnt so that some of the holes 15 are opened, whereupon C0 2 and NH 3 gases carbonate contained in the fire extinguishing material produces C0 2 and formed from the ammonim carbonate according to the equations (I) and (II) cause the fire material to be ejected from the holes 15 in every direction.
  • the fire at the initial stage may be extinguished by the air shielding function of gases and fire protective functions of chemicals.
  • the amount of fire extinguishing material used is generally about one liter per 27 cubic metres of space.
