METHOD OF PREVENTING EXPLOSION AND LOCALISING SPILL OF LIQUEFIED NATURAL GAS AND LIQUEFIED HYDROCARBON GAS WITH COMBINED AIR-WATER FOAM WITH LOW AND MEDIUM EXPANSION RATIO AND FIRE-EXTINGUISHING AGENT AND SYSTEM FOR IMPLEMENTATION THEREOF Russian patent published in 2016 - IPC A62C3/02

Abstract RU 2589562 C2

FIELD: fire safety; emergency containment equipment.

SUBSTANCE: invention relates to equipment for emergency containment, prevention of inflammation and explosion (reduction) and extinguishing of liquefied gases. Method and system for prevention of explosion and localisation of spill of liquefied natural gas and liquefied hydrocarbon gas, involving treatment of surface of liquefied gas with air-water foam with low and medium expansion ratio and along surface of spill of liquefied natural gas and liquefied hydrocarbon gas feeding fire extinguishing agent in form of neutral gases, for example carbon dioxide, nitrogen or complete combustion products or powder fire extinguishing agents, for example, based on sodium bicarbonate or potassium bicarbonate.

EFFECT: invention can be used in power engineering, chemical industry, transport for containment of spills of liquefied natural gas and liquefied hydrocarbon gas.
