Modern Technologies of Fire Suppression
Today, the worldwide work is constantly being performed to develop new, more efficient technologies for fire suppression of industrial and residential facilities, warehouses, forests and field plots, as the fire annually causes huge material losses and environmental damage, and its replenishment takes many years. New technologies for firefighting are being developed considering a reduction of financial and labour costs, reduction of the terms of fire suppression and the use of fire suppressing materials of a new generation.
Liquid fire suppressing agents - film-forming foam generators (AFFF and AFFF / AR) with foam of high and medium expansion, which successfully suppress burning oil and petroleum products, are increasingly used during suppressing of the fires of Class B.
Suppression of the fires of class A (solid combustible substances) is performed with use of the water spayed by a solid jet with wetting additives (foam generating solutions) or polymeric adhesive additives which rapidly form gel structures with water. This allows to reduce the amount of the water supplied to the source of fire almost twice and reduce the time of fire suppression by almost a third. These compositions effectively suppress rubber, natural rubber, plastic, wood and other easily flammable materials.
Moreover, the concentrated gel solution allows to create zones of fire barriers that resist penetration of fire within several hours. Gel additives are quickly mixed with water, easy to transport, can be stored up to 5 years in rough conditions, and do not create problems in managing of the fire consequences. Mixing gel additives with water is performed in dispensers, and their feeding to the fire source is carried out by standard fire suppression equipment — fire hose nozzles or aviation equipment.
Today, much attention is being paid to fire protection during the construction of modern industrial and residential capital facilities. Building materials and finished structures are required to pass fire protection preparation, which reduces their flammability almost twice.
