In the last 50 years, the chemical process industries have moved to large, world scale plants. Because oftheir size, these plants have an increased potential for major accidents such as fire outbreaks, explosions, etc. Recognizing this potential, the industry incorporated many engineered safety features into these plants to manage and control the hazards. This has led to the development and use of better hazard identification and analysis techniques like Quantitative Risk Analysis (QRA) and Hazard and Operability Studies (HAZOP). However, current applied traditional method involves hazard identification to be conducted after any process design has been completed. Contrary, the best way of dealing with ahazard is to remove it completely. The provision of means to control the hazard is very much the second solution. The shift from traditional sequential design to concurrent design has contributed to the adoption of inherent safety measures. As Lees (1996) has said the aim should be to design the process and plant so that they are inherently safer. This report was produced intentionally to introduce the implementation of inherent safety principle into the development of a comprehensive risk model. The model developed will specifically focused on 2 major fire outbreaks in chemical plants namely; jet fire and pool fire. The model provides results in terms of thermal radiation flux plotted against distance to thermal dose. Based on the graphical representation, effects on injury can be predicted.
