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
