Abstract

Oil and most of its products are classified as highly hazardous flammable liquids. In an accident, these fluids sometimes spill uncontrollably and ignite. A spill of oil or oil products leads to environmental disasters, especially when it spills onto the surface of a reservoir, sea or ocean. Additional damage to the environment is caused by their combustion. A flammable liquid fire produces a large amount of harmful, toxic products of complete and incomplete combustion. Putting out a fire as soon as possible means not only saving material values, but also significantly protecting the environment. For violation of environmental safety, the legislation of most developed countries provides for penalties imposed on the owner of the company who caused the accident. The size of these sanctions should correspond to the costs required to return the environment to the state it was in before the accident. Consequently, the degree of reduction of environmental losses due to timely extinguishing of a fire can be estimated in monetary terms.

In this work, using a model of burning 1 thousand tons of oil, a comparison is made between the ecological losses from a fire of a combustible liquid with the costs of extinguishing it with a means based on a fire extinguishing salt immobilized by a thin layer on the inner surface of a porous carrier. It is shown that, even without taking into account the cost of the rescued oil as a material value, the use of such an extinguishing agent for extinguishing can significantly reduce the environmental damage to the environment. This reduction for the proposed model is calculated in monetary terms. It is shown that environmental losses significantly exceed the penalties provided for by Ukrainian legislation. The growth of the economic effect from the introduction of spilled oil extinguishing by the developed means is predicted.
