METHOD FOR THE SUPPRESSION OF HYDROGEN FIRES

A method for extinguishing hydrogen fires comprises introducing to the hydrogen fire a fire extinguishing concentration of 1,1,1,2,3,3,3-heptafluoropropane and maintaining the concentration until the fire is extinguished. The method includes heptafluoropropane at a range of 13-30 % volume/volume in...

Summary:A method for extinguishing hydrogen fires comprises introducing to the hydrogen fire a fire extinguishing concentration of 1,1,1,2,3,3,3-heptafluoropropane and maintaining the concentration until the fire is extinguished. The method includes heptafluoropropane at a range of 13-30 % volume/volume in the air. The fire extinguishing methods also include the use of heptafluoropropane in blend with other fire extinguishing compounds. L'invention concerne un procédé pour l'extinction des incendies d'hydrogène, qui consiste à introduire dans l'incendie d'hydrogène une concentration d'extinction d'incendie contenant du 1,1,1,2,3,3,3-heptafluoropropane et à maintenir ladite concentration jusqu'à l'extinction de l'incendie. Ce procédé consiste notamment à maintenir dans l'air une proportion d'heptafluoropropane comprises entre 13 et 30 % vol/vol. Dans certains cas, le procédé consiste aussi à utiliser l'heptafluoropropane en combinaison avec d'autres composés extincteurs.
