The numerical simulation of gas dispersion and estimation consequence impact is importance in Oil Gas industry's process safety management. For natural fields with toxic components like Hydrogen sulfide, the toxicity zone drives business decisions related to equipment design, facility siting, layout, land use planning, emergency response measures. Proprietary tools or empirical models which are...

In this study the influence of atmospheric conditions, release height and particle size are studied on radiological impact due to a hypothetical 15 KT nuclear explosion using HotSpot model. Simulations show that among different parameters, burst produces highest total effective dose (TED). It is found maximum TED about 4 orders higher for surface compared elevated explosions. The range acute do...

Introduction: Nearly half of occupational accidents in Iran occur in construction sites. Therefore, modeling of occupational accidents in these sites is one of the solutions to design safety strategies to reduce occupational accidents in the field of construction. This study was designed and conducted with the aim of modeling the cause-consequence of accidents in construction sites. Material a...

This work is concerned with the consequence analysis of vapour cloud explosion (VCE) due to accidental release of hydrogen (H2) from the hydrogen holder in a chloralkali plant. Hydrogen is highly flammable if released accidentally may lead to flash fire or VCE which has the potential to damage people, equipment and facilities in the vicinity of the hydrogen holder. The equivalent TNT, TNO multi...
