An assessment of parts of transportation infrastructure in terms of hazards to roadside territory is considered. It is suggested to assess individual segments of road and railway network by estimating risks posed by potential fires and explosions on road and rail. Boiling liquid expanding vapour explosion of tanker trucks and tank cars is identified as the most hazardous and likely high consequence accident in the land transport. It is proposed to express the risk to built roadside objects by means of an annual damage frequency. This frequency is considered to be a specific physical characteristic of the road or railway segment under analysis. It is shown that estimating the damage frequency requires assessing effects of a potential explosion on road or rail and developing a fragility function for the roadside object analysed as a potential target. An example case study is presented. It considers a potential thermal damage to a reservoir (stationary tank) built in the vicinity of a highway. The damage can be caused by an explosion of a propane tanker truck. Results of the risk assessment are expressed in terms of probabilities of specific damage events.

“…Let (O, X, Y, Z) be the set of system axes used for the trajectory description and let O be the departure point for a generated fragment. The fragment trajectory can be described as as shown in Mébarki et al (2009b). After the fragment has been projected, an impact is possible with any potential target that crosses its trajectory.…”

“…Greater mass of the fragment corresponded to the higher initial kinetic energy or the initial velocity [32]. Risk assessment due to the action of fragments is very often estimated in the literature on the basis of kinetic energy of fragments [33]. This energy is usually defined by the percentage share of expansion energy.…”

In this chapter, a simulation model for fragmentation risk assessment due to a cylindrical tank explosion is presented. The proposed fragmentation methodology is based on the application of Monte Carlo simulation and probabilistic mass method. The probabilities of generating fragments during the explosion of the tank were estimated regardless of the available accident data. Aleatoric and epistemic uncertainty due to tank fragmentation has been identified. Generating only one fragment is accompanied by aleatoric uncertainty. The maximum fragmentation probability corresponds to the generation of two fragments with a total mass between 1200 kg and 2400 kg and is 17%. The fragment shape was assessed on the basis of these data and fracture lines. Fragmentation mechanics has shown that kinematic parameters are accompanied by epistemic uncertainty. The range of the fragments in the explosion of the tank has a Weibull distribution with an average value of 638 m. It is not justified to assume the initial launch angle with a uniform distribution, since its direction is defined by the shape of the fragment. The presented methodology is generally applicable to fragmentation problems in the process industry.
