FIELD: fire-fighting, particularly fire-extinguishing equipment adapted to suppress oil, wood, natural gas and derivatives thereof, namely with the use of granular carbon dioxide.
SUBSTANCE: method involves delivering aerated solid granular carbon dioxide to fire site at supersonic outflow velocity. Fire-extinguishing device comprises container to be filled with granular carbon dioxide and granular carbon dioxide delivery means, which supplies granular carbon dioxide to fire site. The device additionally has granular carbon dioxide aeration vessel. Granular carbon dioxide delivery means provides supply of granular carbon dioxide in aerated state at supersonic outflow velocity to fire site.
EFFECT: increased efficiency.
