Definitions

  • the present invention relates to a fire extinguisher, a fire extinguisher, and a fire extinguisher used for fire extinguishing equipment.
  • aqueous fire extinguisher As a general aqueous fire extinguisher, there is a strengthening liquid fire extinguisher (potassium carbonate aqueous solution having a concentration of 35 to 40% by volume). This is effective for fire A (normal fire), fire B (oil fire) and fire C (electric fire), and is particularly effective in extinguishing tempura oil fires, but it is handled because it is strongly alkaline with a pH of 12-13. Attention is required.
  • Conventional fire extinguishing agents including reinforced liquid fire extinguishing agents, do not ensure the safety of the ingredients to the human body. When a fire extinguisher is released due to a fire or misoperation, it is necessary to wash or dispose of the fire extinguisher attached. In other words, because the safety of the extinguishing agent component to the human body has not been secured, secondary damage will occur due to the addition of extinguishing agent in addition to those directly damaged by fire, so this may be reduced It has been demanded.
  • Patent Document 1 listed below describes a fire extinguisher composition for tempura oil fires and tire fires, which uses a carboxylic acid alkali metal salt and a sugar alcohol as main ingredients and water as a solvent as a neutral fire extinguisher.
  • Patent Document 2 describes a fire extinguisher containing trifluorochlorocarbon as a main component and terpenes (including saponin) as a detoxifying additive. Saponins are also known as foam stabilizers for fire extinguishing agents.

  • the natural surfactant has an effect of suppressing evaporation and diffusion of the flammable gas of B fire (oil fire) by foaming and covering the surface of the fire extinguisher.
  • the fire extinguisher of this invention has high fire extinguishing performance with respect to any fire of A fire (normal fire), B fire (oil fire), and tempura oil fire.
  • the fire extinguisher for C fire is different from other fire extinguishers only in the way of extinguishing the fire extinguisher component, the fire extinguisher of the present invention is highly extinguished for C fire (electric fire). Has performance.

  • Lecithin, saponin, and casein are ingredients that are recognized as food additives in Japan. Therefore, the fire extinguishing agent of the present invention ensures high safety for the human body. It is preferable to use the alkali metal carboxylate obtained by mixing and reacting either or both of acetic acid and citric acid and either or both of potassium carbonate and sodium carbonate.

When the content of the alkali metal carboxylate salt exceeds 55 g, the change with time is likely to occur, and the quality change test specified in the Ministry of Internal Affairs and Communications “Ministerial Ordinance for Establishing Technical Standards for Fire Extinguishers” fails. If the content of the natural surfactant is less than 0.10 g, the fire extinguishing performance of A fire and B fire becomes insufficient. When the content of the natural surfactant exceeds 2.0 g, a change with time tends to occur.
