Definitions

  • a fire-extinguishing composition and a fire extinguisher device for use thereof are presented.
  • Said fire-extinguishing composition comprises a composition having the following components in aproximately the proportions by weight as indicated:
  • This invention relates to a fire-extinguishing composition and a fire extinguisher for the application thereof.
  • the invention also relates to a method of extinguishing fires, as well as to a method of making a fire extinguisher.
  • One of the purposes of this invention is to provide a disaster-preventing fire-extinguishing composition which is suitable for storage and which extinguishes fires with a relatively small amount of stored water or other Water from such sources as rivers or lakes during unexpected earthquakes or other like disasters, when the regular water supply may be cut off. It is an object of the invention to provide a fire-extinguishing composition which can extinguish fires at the initial stage of the fire incident by the application of the said fire-extinguishing composi tion. It is a further object to provide a method and device for fire extinguishment.
  • the CO acts as the main fire-extinguishing agent, while the viscous aluminum silicate compounds generated from the water glass, alum, etc., which are the components of the fire extinguishing composition, cooperate with other viscous material, such as sodium dioxide, calcium chloride, etc.. to form a fire-proof membrane or covering over the articles which have not yet burned. This stops the extension of the fire and burning. In other words, it is the covering action of these viscous materials and the fire-extinguishing power of the CO gas which works together to effect fire-extinguishing and fire preventing in a surprisingly efficient manner. Moreover, it is to be observed that the CaCO and MgCO which result from Reaction (III) produce CO gas continuously by repeating Reaction (I) and (II) as long as NaHCO exists in the system.
  • FIG. 1 is a perspective view of the fire-extinguisher of the present invention installed in a room of a dwelling or other structure;
  • FIG. 2-A is an exploded view of the fire extinguisher showing the several parts of the apparatus.
  • FIG. 2-B is a vertical sectional view of the fire extinguisher apparatus.
  • 1 is the container which holds the fire extinguishing composition 2 of the present invention.
  • 3 is the supporting frame for the fire extinguisher.
  • 4 represents the cushion material against which the container 1 is held by the spring band 5.
  • FIGS. 2-A and 23-8 there is a specially strengthened glass container 1 in the form of a cylinder, vessel, or some other type, which breaks into small pieces as soon as the container is heated at an elevated temperature below 100 C.
  • the container is filled with a fire-extinguishing solution 2 prepared according to the present invention and then the container is sealed.
  • Said container is fixed to a supporting frame 3 by means of spring bands with cushion material 4 as interpositioner, and then covered with a cover 7 made of synthetic resin, such as hard polyethylene, etc.
  • the fire-extinguisher of the present invention is fixed in place somewhere near combustible materials, for example, on the ceiling (b) of a kitchen room (a), the said container 1 bursts into small pieces through the action of spalling (sudden heating and cooling) as the said spring is heated by the burning cover 7 in a fire accident.
  • the fire-extinguishing solution originally contained in the said container spreads, e.g., in form of a mist, over the burning articles by means of the gases generated, and thus exerts a strong fire-extinguishing action.
  • the number of fireextinguishers to be used according to the present invention is determined on the ability of the fire extinguisher to put out fires.
  • One extinguisher for about every 7-10 m? is preferable, for example.
  • the fire-extinguisher of the present invention is also advantageously hung cm. below the ceiling, or fixed on a wall at a place about 10 cm. apart from the ceiling. In any case, it is essential that the fire-extinguisher apparatus be firmly fixed in place on the wall or ceiling.
  • the filled extinguisher was fixed on the upper inner wall of a house wherein shavings were heaped. Two liters of a mixture of heavy oil and gasoline were spread thereon and then the shavings were ignited. The fire became stronger and stronger, and 8l7 seconds after ignition, the glass container fixed in the upper side of the room exploded spontaneously owing to the rising flames. Meanwhile, the flames and black smoke changed into a white smoke. The fire was perfectly controlled within 2-5 seconds after the said spontaneous explosion.
  • EXAMPLE 2 To illustrate the effect of the concentrated solution of fire-extinguishing composition, according to the present invention, the same solution as in Example 1 was made, but the concentrated fire-extinguishing solution was diluted to times by volume and every 200 g. of it was packed into a vinyl bag. When one of the said 200 g.-bags of the fire-extinguishing composition of the present invention was applied to the fire at its strongest stage (13-15 see. after ignition), the fire was quickly extinguished. In contrast, 4 to 5 of the 200 g.-water-vinyl bags was necessary to extinguish the fire at the same conditions.
  • Amt. of Water needed for fire-extinguishment Amt. of diluted fire-extinguishing solution needed for fire-extinguishment :4-5 (for 100 times diluted solution)
  • the optimal degree of dilution depends upon the kinds of the burning articles and the environments.
  • Method of extinguishing fire in a building which comprises using a fire-extinguishing composition consisting essentially of an aqueous solution of (a) from about 7.0 to about 7.5 parts by weight of burnt alum,
  • composition of claim 3 which composition is diluted with up to about 100 parts by volume of water.
  • composition of claim 2 which composition is diluted with up to about 100 parts by volume of water.
