HAZID, Fire, Explosion, Risk & HSE Case

The objective of this E-Course is:

· Compliance with all applicable Health, Safety and Environmental for development of HSE case

· Identify all potential hazards and assess their consequences and probabilities

· Develop prevention, control and mitigation measures to eliminate or minimize hazards to people, asset and environment

· Minimize the risk associated with operation of the plant by reducing risk to a level which i s “As Low As Reasonably Practicable” in compliance with project risk acceptance criteria

The Following subjects will be discussed:

· HAZID methodology and Terms of Reference as an input to Risk Assessment

· Failure cases definition’ which shall identify isolatable process sections based on ESDVs, SDVs.

· Fire & Explosion consequence modelling

· Preliminary Risk Assessment (PRA) based on COMPANY Risk Matrix

· Detailed Risk Assessment (DRA) Based on COMPANY Risk matrix

· Quantitative Risk Assessment (QRA) to define IRRA and PLL and FN curves

· Risk Reduction Workshop (RRW)

· ALARP demonstration

· HSE Case development

· SIMOP hazard identification

Dispersion simulations will be discussed to determine realistic potential flammable cloud sizes for the subsequent explosion simulations considering the leak location and direction, the stream characteristics, the leak rate and the wind characteristics. Scenarios to be studied for dispersion simulation shall be based on the review of the existing failure cases and the new failure cases as part of the Fire & Explosion consequence modelling.
