Method for calculating fire risk taking into account the use of fire extinguishers on production facilities with liquid motor fuel
Under this science article took place an analysis of the usage of powder fire extinguishers in the calculation of fire risk and the conduct of a quantitative analysis of the risk of accidents at hazardous production facilities in the Russian Federation and in foreign countries. Based on above mentioned analysis method of calculation fire risk is offered. That method taking into account the usage of powder fire extinguishers at production facilities of the oil and gas complexes, where flammable and combustible liquids, with a flash point higher than the ambient temperature. The method is based on the determination of the useful effect of the usage of powder fire extinguishers in the potential area of the oil spill, where it is suitable to use the specified type of fire extinguishers. The article provide an example of determining the potential risk at a pumping station for deliver diesel fuel, taking into account the application and without it. The object of the research is the effectiveness of the usage of powder fire extinguishers in extinguishing fires in oil product spills at oil and gas production facilities. The subject of the research is improvement of the fire risk calculation methodology taking into account the effectiveness of the usage of powder fire extinguishers at the production facilities of the oil and gas complex. Methods. The general scientific methods of research (system analysis, probability theory, heat exchange, formalization, statistics and analogy) are applied when the work is performing. Results: 1. Through the article the effectiveness of the usage of powder fire extinguishers to extinguish the fire of the spill of oil products at the initial stage of its development is determined. 2. A methodology for assessing fire risk at production facilities of the oil and gas complex has been developed, taking into account the use of powder fire extinguishers. Scope of application of the results : the results obtained make it possible to increase the reliability of the safety assessment of oil and gas facilities by taking into account the effectiveness of powder fire extinguishers in case changes are made in legal acts and methods for calculating fire risk. Conclusions. The application of the proposed methodology for calculating fire risk, considering the usage of powder extinguishers at oil and gas facilities, increases the objectivity of fire hazard analysis of protection facilities, which is justified by calculating the contribution from the use of fire extinguishers in calculating fire risk.
