FIELD: fire fighting chemicals. ^ SUBSTANCE: invention refers to chemical extinguishing measures including gas-forming chemically active substances and, more precisely, to substances retarding chemical reactions containing organic compounds. It can be used to protect industrial premises where hydrogen is produced as a target or by-product, also for storage and transportation of hydrogen. Gas compound preventing inflammation and explosion of hydrogen-air mixture includes hydrocarbon deterrent containing 2-8 atoms of carbon diluted by phlegmatizing carbon dioxide. Gas compound is two-component. As a deterrent, it contains i-C4H8 isobutene - at least 5.0% of protected volume given optimal ratio of components, vol. %: isobutene/carbon dioxide - 1:2.4. The invention ensures guarantee prevention of inflammation of hydrogen-air in the protected volume in all ratios of all its components. ^ EFFECT: retardation of chemical reactions containing organic compounds thus allowing extinguishing fire. ^ 1 dwg, 1 dwg |
