Yanğın təhlükəsizliyiTopics

Types of combustion, combustion products of fuel, combustion temperature and heat of combustion are one of the basic concepts of fire safety. in this topic, the essence of the combustion process, the conditions of its occurrence and the characteristics of different types of combustion are studied. gases formed during combustion of fuels, heat amount and temperature indicators are also explained. this knowledge helps to understand the causes of fires and how to prevent them.

Physico-chemical analysis of the combustion process studies the mechanism of combustion, factors affecting it and energy transformations. in this topic, the composition of fuel, oxidation reactions, temperature changes and properties of combustion products are investigated. the rate of combustion, heat release and physico-chemical factors affecting the process are also explained. these analyzes allow determining the causes of fires and choosing the right safety measures.

Thermal autoignition, chain theory of oxidation, and adiabatic ignition are concepts that explain the basic mechanisms of combustion processes. in this topic, the causes of ignition of substances as a result of thermal and chemical reactions without an external source of ignition are studied. the role of chain reactions in the oxidation process and the phenomenon of adiabatic ignition without heat exchange are also investigated. the study of these processes allows to determine the causes of fires and to choose preventive measures.

The course of reactions in the combustion process studies the physico-chemical transformations that occur as a result of the interaction of substances with oxygen. in this topic, oxidation reactions during combustion, heat release and factors affecting the reaction speed are explained. the effect of fuel composition, temperature and oxygen content on the combustion process is also investigated. studying these processes helps to understand the mechanism of combustion and the causes of fire hazards.

Explosion information is one of the main sections of fire safety and studies processes accompanied by rapid energy release. in this topic, the characteristics of quiet combustion and explosive combustion processes, pressure, temperature and volume changes during the explosion are explained. also, the characteristics of explosive and fire-hazardous dusts, their causes and the risks caused by them are investigated. this knowledge is important for the prevention of explosions and the proper organization of security measures.

The calculation of the upper and lower limits of explosion is one of the main calculations for fire and explosion hazard assessment. in this topic, the concentration limits at which gas, vapor and dust-air mixtures can cause an explosion are studied. also, the concepts of lower explosive limit (lel) and upper explosive limit (uel), their determination and calculation methods are explained. these indicators are used to prevent the formation of dangerous mixtures in production processes and to choose protective measures.

Fire hazard indicators of substances are used to evaluate their burning properties and degree of danger. in this topic, the concepts of combustion, spontaneous combustion, ignition and ignition temperature, and their causes are studied. it also explains the stages of the combustion process and the course of the scheme. these indicators play an important role in the safe storage, transportation and use of substances.

Mövzu çərçivəsində şəbəkə təhlükəsizliyinin əsas anlayışları, məqsədləri və prinsipləri öyrənilir. şəbəkə infrastrukturunda məxfilik, bütövlük və əlçatanlığın təmin edilməsi, təhlükəsizlik siyasətlərinin hazırlanması və təhlükəsiz şəbəkə idarəetməsinin əsas prinsipləri nəzərdən keçirilir. həmçinin şəbəkə aktivlərinin qorunması, girişə nəzarət və təhlükəsizlik risklərinin idarə olunması məsələləri araşdırılır.

Ignition and self-ignition processes are one of the main indicators that determine the fire hazard of substances. in this topic, ignition and spontaneous ignition temperature, ignition impulse and conditions of their formation are studied. the calculation of heat and energy indicators of the combustion process is also explained using the ormandy-grexan and thornton formulas. these concepts are important for assessing the fire hazard of substances and preparing safety measures.

The concentration and temperature limits of ignition (explosion) are one of the main indicators for assessing the fire and explosion hazard of substances. in this topic, the lower and upper concentration limits at which gas, vapor and dust-air mixtures can ignite are studied. it also explains the temperature conditions required for an explosion to occur and the factors affecting ignition limits. these indicators are used to prevent the creation of dangerous mixtures in production processes and to select protective measures.
