A STUDY OF THE FIRE BEHAVIOR AT A HYBRID VEHICLE FILLING STATION

Fire safety issues at protected facilities are currently closely intertwined with financial investments. Therefore, it's not surprising that various options are being proposed to reduce the latter without compromising overall safety. Some of these methods include combining similar technological processes and grouping facilities according to functional fire hazard class. A typical global example is the construction of combined (hybrid) petrol stations, which reduce capital and operating costs and conserve land resources. In this case, specialists must ensure a comprehensive approach to protecting the population and their property. However, both fuels (hydrogen and gasoline) are explosive substances that can lead to catastrophic consequences. To prevent destructive situations at such facilities, it is necessary to conduct a fire hazard assessment and determine the fire risk. In our study, the risk assessment was conducted using specialized software across various scenarios. The most dangerous scenario was identified as a hydrogen leak from the dispenser, leading to a flare-up fire that, in turn, destroys the gasoline dispenser, causing a secondary accident. This study can serve as a basis for determining safe fire distances between process equipment and optimizing the layout of the protected facility.
