Method of fire hazard assessment of oil and gas industry production technology

Abstract

Introduction. Fire risk can be assessed qualitatively and quantitatively. A qualitative method for assessing fire hazard of the technological process (risk analysis) involves a detailed consideration of possible deviations from the technological regulations and failures in the production technology. Therefore, it can significantly increase the reliability of the hazard analysis to justify the technical decisions made to improve fire safety of production. Goals and objectives. Quantitative methods for analyzing fire hazard of technological processes and assessing fire risk have a number of significant drawbacks, they use various models, in which not always reasonable assumptions are often made. The use of such methods sometimes casts doubt on the results obtained. Hazard analysis using a qualitative analysis method is a sequential process of identifying violations not only of technological regulations, but also of fire safety requirements, and, consequently, the causes of accidents. Therefore, one of the most important purposes of this process is to check that all fire safety requirements are met. Methods. Method for assessing fire hazard of production technology by analyzing the consequences of "What happens if...?" (qualitative method of fire hazard assessment) allows us to consider problems related to possible causes of damage to technological equipment, the consequences of these causes, and the options adopted in the considered production for their prevention. The method is based on the development of a list of hazards, their division by hazard level and determining the most dangerous situations on this basis. Such a division makes it possible to increase the efficiency of the developed technical solutions that increase the level of fire safety of the production technology. Results and discussion thereof. The article reveals the essence of the method for assessing the fire hazard of production technology by analyzing the possible consequences of violations of technological regulations. The place of this method in the expert assessment of the fire hazard of production is shown and an example of the practical use of the method is given. Conclusion. Qualitative method of assessing fire danger of the technological process can complement quantitative methods, it can be their integral part, for example, when calculating the fire risk of production facilities, and it can act as an independent method for small enterprises in which it is not required to conduct a state expertise of projects, as well as when there is a need to assess compliance with fire safety requirements of the technical solutions adopted at the stages of design and operation of production.
