METHOD TO PREVENT FIRE IN PEAT-BOGS AND LIGNIN SEDIMENTS Russian patent published in 2007 - IPC A62C3/02 

FIELD: fire-fighting, particularly to prevent natural-source and industrial-source fires.

SUBSTANCE: method involves determining critical peat-fog or lignin humidity by deep prospecting thereof along with trench digging-out and filling with non-combustible material, wherein the trenches are made as slots having depths equal to distance for peat layer with critical humidity; creating shielding wall of non-combustible material to be supplied in trenches, wherein the non-combustible material is flowable weakly-hardening gel-forming solution. Peat-fog or lignin humidity is determined on pitch selected from distance to fire-site. Slot-like trenches are formed with the use of cable-laying means. The gel-forming solution comprises clay-based and cement-based mineral components mixed with structure-forming agent.

EFFECT: possibility of preventive possible fire site localization and increased speed of existent fire site suppression by rapid delimitation thereof with shielding walls made of non-combustible material, which may be converted from fluid into still state.
