The purpose of this study is to identify hazards, evaluate risks and suggest safety measures in order to prevent fire and explosions due to the uncontrolled charging and the ignition of jet propellant 8, shortly JP-8, at the fueling stations in the aerospace industry. There are many different surveys on the ignition and the explosion of the fuels in the literature. However, not enough researches have been made in order to model the dispersion of the JP-8 spill in aviation. JP-8 is a petroleum product which has wide usage in aviation as a jet engine propellant. JP-8 is a flammable hydrocarbon mixture and its vapors can be ignited very quickly. JP-8 vapors can start a fire and explode in open air or in the confined spaces in case of exposure to flame, spark, heat, static electricity discharge and different types of ignition sources. A case scenario of JP-8 spill during the fueling operations in the aviation sector is investigated to model evaporation of JP-8 spill and dispersion of its vapors. Different evaporation and dispersion models are discussed and compared for deciding the most suitable model for the JP-8 spill. According to the assessment results, the area affected by the JP-8 spill and evacuation zones are defined. This research provides the required information to design safe fueling stations and to increase the safety during fueling operations for the aerospace industry.
