SF3005 Hazard Analysis and Risk Assessment Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

1:To learn the various techniques for hazard identification, reliability analysis, estimation of frequency of occurrence of hazards, consequence analysis, risk quantification and human reliability analysis.
2:To provide knowledge in Quantitative Risk Analysis Process Industries
3: To provide in-depth knowledge of risk Control and Management
4:To familiarize the student with various types of Hazard Identification techniques
5:Identify various Hazards related to the work practices and activity using various technique.

UNIT I HAZARD IDENTIFICATION AND RISK ANALYSIS

Hazard and risk, Types of hazards – fire, explosion and toxic gas release, Structure of hazard identification and risk assessment. Identification of hazards : Inventory analysis, Fire and explosionhazard rating of process plants – Preliminary hazard analysis, Hazard and Operability study (HAZOP),Case studies.

UNIT II RISK CONTROL & MANAGEMENT

Plant availability and process reliability: ways of improving plant availability, MTBF and MTTF, thereliability function, failure rate, bathtub curve, probability relationships, simple reliability estimation.The logic tree approach, set theory and Boolean algebra, application to probability, Boolean manipulation. Event tree analysis – notation.Failure mode and Effect Analysis (FMEA) – methodology, criticality analysis, corrective action and follow-up.

UNIT III ENVIRONMENTAL HEALTH RISKS

Consequence modelling: Source models – discharge rate models, flash and evaporation, dispersion models. Explosions and fires -vapour cloud explosions, flash fires, physical explosions, BLEVE and fireball, confined explosions, pool fires, jet fires. Effect models -dose-response functions, profit functions,toxic gas effects, thermal effects, explosion effects.

UNIT IV HAZARDS MONITORING AND EMERGENCY MANAGEMENT

Quantification of risk: QRA, Vulnerability analysis, accepted and imposed risk, perception of risk, risk indices, individual risk and societal risk, acceptance criteria for risk, ALARP, Presentation of measures of risk – risk contour, F-N curve. Calculation of individual risk and societal risk. Human reliability analysis (HRA) factors leading to human error, characteristics of HRA techniques, Technique for Human Error Rate Prediction (THERP),Accident Sequence Evaluation Program (ASEP).

UNIT V DISASTER MANAGEMENT IN INDIA AND RELIEF

History of disasters – various disasters in various countries – Disasters in India Relief and rehabilitation in disasters at local, national and global levels, Gaps in disaster management identified on analysis Worldwide Aid and Agencies, Study of different case studies on natural disaster & manmade disaster

TOTAL: 45 PERIODS
