METHOD OF FIRE ISOLATION AND EXTINGUISHING IN RECEIPTS AND STORAGE AREAS FOR INFLAMMABLE AND COMBUSTIBLE LIQUIDS IN HORIZONTAL TANKS Russian patent published in 2011 - IPC A62C3/06 

FIELD: fire-fighting means.

SUBSTANCE: invention refers to fire-fighting equipment. A method involves fixing a metal grid in a fire area, supplying thereto a fire extinguishing coolant, and differs by the fact that the fire-resistant metal grid of mesh width determined by offered formula, and grid wire thickness related with cell diameter by the ratio d_wire≥ 0.25 d_mesh. is rack-mounted vertically on four sides of the area to height of a bottom edge of a shed mounted over the area with tanks; the fire extinguishing coolant is supplied from gas powder modules arranged along the periphery in the fire area and along the whole enclosure at intensity 0.01 kg/m³·s and more; the fire extinguishing coolant is presented with a mixture of a gas inhibitor and/or a gas retarder with a heterogeneous flame retardant containing at least 5% of fraction of said dispersion of particle sizes commensurable with maximum wave radiation length of burning liquid or gas flame. The gas powder modules are provided inside or outside of the enclosure in pairs opposite to each other with regarding counter extinguishment of stream speeds in the enclosure.

EFFECT: improved efficiency of the method.
