FIELD: fire-prevention facilities.
SUBSTANCE: invention relates to fire-prevention chemical substances, in particular, to gas compositions of chemically active substances designed to prevent inflammation and explosion of methane-air mixtures at industrial enterprises, transport and household facilities. The gas composition for prevention of inflammation and explosion of methane-air mixtures consists of a fluorine-carbon-containing inhibitor - trifluoromethane with the chemical formula CF3H and a dissolvent - tetrafluoromethane CF4 and/or nitrogen N2.
EFFECT: proposal provides for guaranteed automatic prevention of inflammation and consequently explosion of methane-air mixtures in enclosed spaces under all concentrations of methane and from any initiating pulses.
