Influence of driver error on the level of hydrogen refuelling station risk.

This study investigates the relationship between car drivers' approaches to hydrogen refilling and the associated risks. The focus is on a dispenser operated directly by drivers. The awareness of the consequences of careless operations on hydrogen installations differs among drivers. In this study, models of cautious and careless drivers were considered to analyse how their approach affects the risk of the refuelling process. This research involves the development of scenarios for hazardous events and their consequences, such as fires or explosions. The probabilities calculated for the scenarios, together with the death probabilities for the consequences, allowed us to determine the risks and compare the results for a cautious and careless driver. The highest values of the risk obtained in the research for cautious and careless drivers were 7.68⋅10−5 and 3.22⋅10−4. [Display omitted] • A hydrogen refuelling station is a structure of objects that may cause failures. • The analysis includes assessment of experts and fuzzy logic. • Consequences such as a fire or an explosion are investigated. • The calculated risk determines a hazard area around the analysed object. • The driver's experience is an important factor determining the safety of refuelling.
