Abstract
In chemical processes, fire and explosion prevention is crucial, especially when flammable liquids or gases are present because they can create explosive atmospheres of gas or vapour in the air. These include oil-based products and organic solvents. It is essential to understand these compounds' characteristics as well as the size of an explosive atmosphere. Explosion hazards as well as the locations where explosive atmospheres are present can be identified and assessed. Safety data sheets also contains crucial information on explosive limits. It is important to establish by physical determination the explosion properties of process chemicals in order to provide recommendations for explosion protection and explosion prevention. The purpose of this research was to identify the experimental explosion properties for a few chosen items, such as LEL and minimum ignition temperature. The studies were completed in line with EN 1839 by method B and IEC 60079-20-1. The experiments were carried out in a 5 dm3 internal volume, closed, spherical vessel and in standard oven for minimum ignition temperature.
