Summary
Explanation of the role and method of doing the analysis of hazard of toxic substance release, fire origin and explosion during dangerous substance storage, production and treatment and the assessment of associated risks. Methods of hazard identification in technological processes used in the world and also in the Czech Republic.
Learning Outcomes of the Course Unit
Assess how to perform risk analysis of toxic substances, fire and explosion in storage, production and processing of dangerous substances and assessment of associated risks. Compare methods for identification of risk sources of technological processes used in the world, and CR. Explain to estimate the consequences of accidents under various process conditions and for various disorders and variations. Recommend to selected physical and chemical processes.
Course Contents
1. INTRODUCTION
The importance of analysis and justification for implementation. Analysis of the causes of leakage, fire and explosion in the handling of hazardous chemical substances and preparations - highlighting the nature of the process and working conditions. Possible disturbances, deviations from the technology and human error.
2. PROCESS ANALYSIS AND RISK ASSESSMENT OF TECHNOLOGICAL PROCESSES
Explanation of basic terms (hazard, risk, major accident, safety)
procedure for the analysis and its applications.
3. PHYSICO - CHEMICAL PROPERTIES and the TECHNICAL SAFETY FEATURES
Highlighting the knowledge of physical and chemical properties of TSF and chemical products (primarily liquids and gases), the influence of various factors TBP and their direct applicability in practice.
4. METHODS FOR IDENTIFICATION OF SOURCES OF RISK
Unsystematic methods - such as security audit, what happens when ..., method of inspection records. Relative ratings - index methods. Selective method of choice for QRA.
5. METHODS FOR IDENTIFICATION OF SOURCES OF RISK
Systematic methods - such as FTA, HAZOP, FMEA, approx.
6. LIKELIHOOD OF ACCIDENTS
Explanation of the concept of probability and frequency. The methods used - such as FTA, FMECA, Markov analysis, Application of Markov analysis, reliability block diagram.
7. GRAVITY OF THE IMPACT OF ACCIDENTS
Estimation of severity of the impact to humans, living environments and economic losses - Computational method of origination hořlavého souboru (flammable or explosive) za various process conditions even with different disorders and variations, the calculation zón contamination.
8. COMPUTER PROGRAMS TO ESTIMATE THE IMPACT OF ACCIDENTS
Principle Programme ROZEX (Single release, the continuous release of defined - for toxic and flammable chemicals, the phenomenon of BLEVE, surface fire, "take the fire," etc., the program TEREX Aloha program, the program Whazan, Effect program.
9. QUANTITATIVE ANALYSIS AND RISK ASSESSMENT OF CHEMICAL PROCESSES.
To QRA, description and discussion of each step, possible use of the methods, possibilities of risk assessment.
10. IAEA - TEC DOC 727
Společenskéko method of estimating risk - principles and applications, solutions accident model (both in production and during transport).
11. RISK ASSESSMENT AND RISK OF SELECTED RELATED TECHNOLOGY
Physical processes - heating, drying, rectification (distillation).
12. RISK ASSESSMENT AND RISK OF SELECTED RELATED TECHNOLOGY
Chemical processes - types of reactors and to assess their risk.
13. COMPREHENSIVE RISK ASSESSMENT AND RISK RELATED SELECTED TECHNOLOGY
Production of vinyl chloride and PVC.
