METHOD OF FIRE-FIGHTING ON PEAT BOG Russian patent published in 2003 - IPC

FIELD: fire-fighting. SUBSTANCE: method involves laying trench to peat bedding depth; filling trench with inflammable material, such as peat moss, with following moistening thereof. Peat moss absorbs large amounts of moisture due to increased moisture absorbing capacity and keeps moisture for prolonged time. Upon approaching of fire to trench, peat moss is heated to result in intensive steam generation. Steam replaces atmospheric air from trench cavity to create oxygen-free medium and simultaneously to penetrate into and moisten porous trench walls. While being under oxygen-free steam conditions, wet peat moss is incapable of burning to prevent fire from spreading beyond localized zone. EFFECT: reduced water consumption, elimination of necessity for transportation of inflammable materials and reduced labor intensity.
