Assessment of compliance with fire safety requirements of the poultry house for 200,000 heads of “Avangard LLC” in Republic of Mordovia based on fire risk calculation

Abstract

This article presents the results of the assessment of compliance with fire safety requirements of the building of the poultry house for 200,000 heads of Avangard LLC of the Republic of Mordovia, made on the basis of fire risk calculations. The analysis of factors affecting the quality and reliability of the results of calculations is carried out. During the research and evaluation of the objects compliance with fire safety requirements were guided by the provisions of the Technical regulations on fire safety requirements. A list of technical regulations applicable to the object under study was defined. The article gives the fire-technical characteristics of the object under study, the class of functional fire hazard (agricultural buildings). The conducted research has established that the object of research meets the requirements of fire safety. Calculations on fire risk assessment were fulfilled by comparing the calculated values of fire risk with the normative value. For the considered object of protection the fire hazard analysis including the analysis of building characteristics (space-planning, design and technical solutions), fire protection systems, and features of functioning taking into account contingent and distribution of fire load in rooms was completed. The calculation of the risk of the gas supply system was considered the impact of the flame during the combustion of gas released in case of emergency depressurization of the pipeline. The potential risk in a poultry house near a gas pipeline with a diameter of 50 mm will be 1.7810-5, near a gas pipeline with a diameter of 70 mm - 4.410-7, and in total - 1.82410-5. The individual fire risk for employees of the poultry house building is 8.3110-7 year-1. Calculations of the spread of fire hazards and the time of evacuation of people are made using software that allows to create graphical models of space-planning solutions of buildings. With the introduction of the fire risk assessment system at the legislative level, the owners of objects have the opportunity to optimize the cost of fire safety with the required level of safety of people.
