Course detail

Safety Engineering

FSI-KBIAcad. year: 2013/2014

Safety engineering is a progressive and fast growing field closely related to process and environmental engineering. The basic questions are identification of danger (the sources of risk of a serious accident) and determination of the level of risk (estimation of the frequency of occurrence of the accidents). The course focuses on the overview of great industrial accidents, on Czech and European legislation, on the overview of possible consequences of release of hazardous chemical substances and mixtures on the basis of their physical chemical characteristics. The second part of the course consists of the overview of methods that are used in industrial practise for identification of sources of risk of serious accidents (screening, index and selective methods). Finally follows a detailed analysis of the sources of risk of a serious accident via methods (e.g. HAZOP, FTA, ETA) of modelling of the consequences and determining of acceptability of social risk.

Learning outcomes of the course unit

Students will get acquainted with basic methods and procedures of safety engineering which requires incorporation of various aspects such as technical, financial and environmental which may impact the safety of the equipment.

Prerequisites

The subject requires students to have basic knowledge of probability of random events, flowing (and outflow) of gases and liquids through pipelines; in addition to that students must possess knowledge of physical chemical properties of hazardous substances, basic phase balances of liquids – steam for pure components.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Award of credit is conditioned by presentation of semester paper and active participation in seminars. In justified cases, the teacher may present an alternative condition. The test is written.

Aims

Students will be introduced into preventive approach towards safety of elaborated storage or process installation. Large-scale industrial accidents show consequences of serious mistakes in all stages of service lifetime of the equipment. This seminar presents up-to-date methods and procedures developed in hi-tech European countries and worldwide for assessment of safety of individual pieces of equipment and/or whole industrial complexes.

Specification of controlled education, way of implementation and compensation for absences

Participation in the seminar is regularly checked. In justified cases, seminar may be substituted by an individual project (in the form of practical case study).
