Chemical processing plants may contain variety of associated hazards that stem from nature of processes or even the peril of substances. Therefore, it is vital to fully understand their hazards and measure their risks accurately. In the context of Malaysia, quantification of risks is crucial for compliance to CIMAH 1996 sub-regulation under OSH Act 1994 regulations. The quantification of risk or QRA is carried out by estimating likelihood and consequences of hazardous events, and expressing the results quantitatively as risk to people, environment or businesses. QRA analyses complex consequences i.e. possible flammable, explosive or/and toxic effect, from discharges/releases of liquids and/or vapours, taking account of local population and weather conditions, to quantify the risks associated with the discharge/release. In QRA, a large variety of complexities can be found, from simple and deterministic to very extensive and stochastic. Therefore, this 3-days course intends to introduce concept, methods and tools needed in risk assessment for new, expansion and modification of existing plants. This course will provide the theory and hands-on training related to consequence modelling and quantitative risk assessment for conformance to regulations and assurance of safer industrial environment. Safeti (Software for the Assessment of Flammable, Explosive and Toxic Impact) is the user-friendly industrial standard software for carrying out quantitative risk analyses of onshore process, chemical and petrochemical facilities or analysis of chemical transport risk. Safeti is capable of quantifying risks associated with any installation including risk contours, FN curves and rankings of risk contributors. It is also a major decision support tool for organisational strategic planning, facility siting and layout, and for detailed risk and safety assessments. Participants will get the opportunity to learn about risk, the applications of risk involved with industrial activities, and how to practice risk-informed decision-making and risk management.    


Upon completion of this course, participants will be able:
  • Understand the principles of QRA
  • Perform QRA to support decision making regarding the tolerability of the risk of catastrophic accidents
  • Apply appropriate risk reduction strategies to prevent and control risk
  • Conduct consequence analysis (for toxic release, fire and explosion) and QRA using DNV-SAFETiTM software


  Dr. Risza Rusli, is an Associate Professor in Chemical Engineering Department, UTP and currently is the Head of Centre for Advanced Process Safety (CAPS). She is an Associate Member of IChemE in Process Safety. Her first involvement in the research and consultancy on risk analysis was back in 2001 with the AEA Technology, UK. Since then, she has actively involved in the research and development of measurement tools for inherently safer design, consequence analysis for carbon capture technology by applying Computational Fluid Dynamic technique and risk based tools considering human factor elements for the application of chemical processing, oil and gas industries. Since 2007, she has involved in providing professional courses related to Process Safety and conducted consequence study and QRA consultancies for oil and gas companies in Malaysia.         Assoc Prof Dr Mohammad Shakir Nasif is an associate professor at Universiti Teknologi PETRONAS. He has over 20 years of industrial and academic experience in the field of mechanical and fire engineering. He has worked with international consultants in Australia, New Zealand, and Middle East in the field of fire engineering, and fire safety and protection engineering. He has been an invited speaker in several fire safety conferences and supervised research students in fire safety and protection engineering. He has published more than 70 peer reviewed journals and conference papers, and technical reports.       Mr. Mohamad Fazaly Mohamad Ali,  is a Staff Engineer, Process Safety with Group Technical Solutions, PETRONAS. He has 20 years of experience in the chemicals and oil & gas industry in plant operations and maintenance, and process safety. He graduated with a Bachelors of Science (BSc) in Chemical Engineering from the University of Wisconsin-Madison, USA. Fazaly has been conducting PHA studies such as HAZOP, HAZID and LOPA for design projects and operating facilities since 2002, as well as conducting QRA and other technical safety assessments for onshore and offshore facilities since 2009. Having being formally trained as an HSEMS Tier 3 Auditor he frequently conducts audits on PETRONAS projects and operating facilities (on behalf of PETRONAS Group), in addition to audits of Malaysian Petroleum Arrangement Contractors (on behalf of Malaysia Petroleum Management).  Fazaly also conducts training on various subjects related to process safety for the PETRONAS Group.
