The term "explosive atmosphere" is frequently encountered in industry. Typically hazardous areas are found in chemical plants, refineries, paint and varnish workshops, plants for goods grinding, in the storages of combustible gas, liquids and solid substances. In such hazardous areas we must always pay attention to all normal but also abnormal work conditions that can trigger an explosive atmosphere to occur.
Areas at risk of an explosive atmosphere involve diverse hazards (fire risk, injury risk, natural disaster risk, explosion risk etc.). In view of this, it is important to define a level and limits of risk assessment that is conducted in a plant at risk of an explosive atmosphere.
Risk assessment in areas that are at risk of an explosive atmosphere must identify and analyse any hazard or a possible event that could cause an explosion. This paper has conducted a risk assessment at work positions and Ex areas at risk in in Brod Oil Refinery. Risk assessment was conducted in 2015.
