The incorporation of Fuel Cell Electric Vehicles (FCEVs) in public transport is a fundamental step towards the minimization of the emissions due to transportation globally. In-depth studies are required regarding the potential risk from the storage of hydrogen, the transportation of hydrogen to refuelling stations and the refuelling procedure. Thus, it is a prerequisite to establish a holistic baseline which is related to FCEV safety during operation/maintenance, especially to a country in which the sales of these types of vehicles are significantly low. This paper suggests the employment of operational risk management methodology. Relevant experts and stakeholders requested to fill out an "Event-Probability Matrix" per scenario of likely hazards. This research estimates the interest of the local society about technological hazards and the conviction that hydrogen vehicles could be as safe as conventional vehicles. Additional critical scenarios related to the hydrogen storage are analyzed. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
