Abstract
The analysis of the causes, the development process of the catastrophic fire, including a series of subsequent explosions, is given. The reason of the failure of the extinguishing operation is open – low efficiency in localizing and extinguishing the fire, despite the dedicated work of more than 1,000 firefighters (21 fire brigades) with 150 power fire trucks. It is shown that the main reason for the rapid and large-scale development of the catastrophe was the low range and scale of the delivery of extinguishing agents; inflexible, slow change of modes of submission of agents; lack of technique for supply the gas-sprayed sand, inert dust, which became necessary to extinguish burning chemical-active materials, in compatible with water, foam in agents and powder are ineffective. A new modernization of impulse fire-equipment and automatic fire-extinguishing systems is proposed to localize and extinguish fires in terminals of containers, coal, oil, gas warehouses, cargo-berths. The modernization consists in additionally equip in the existing automatic fire-extinguishing systems in the ports at the launching sites with multi-barrels modules (MM) of volley spray in creating a parallel executive system of several MM place around the fire and explosion hazard site at distances from 50 to 200 m. This will make it possible to improve the efficiency of fire-extinguishing and to provide effective light and thermal protection and prolong the life of expensive start-up designs. The validity of the proposed project is confirmed by the results of the last successful demonstration tests of the MM system, placed in a semi-circle around the target and focused their volleys on one local, powerful fire.
