Course detail

Safety Engineering

FSI-KBIAcad. year: 2010/2011

Safety engineering is a progressive and fast growing field closely related to process engineering and environmental engineering. Fundamental issues involve danger identification (risk sources) and determination of degree of a risk (guess of frequency of event occurrence). Subject focuses on large scale industrial accidents, relevant EU and CR legislation and overview of possible consequences of hazardous chemical substance leakage. Second part of the course is devoted to overview of methods used in practice to identify risk sources of serious accidents (screening, index and selective methods). This is followed by detailed analysis of risk source of serious accidents using FMEA and HAZOP methods, consequences modeling and determination of risk admissibility for a community. The whole concept of the seminar is based on approach to process and equipment safety developed by Centre for Chemical Process Safety under AIChE.

Learning outcomes of the course unit

Student 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

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

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. Test is written.

Aims

Students will be introduced into prevention approach towards safety of elaborated storage or process installation. Large scale industrial accidents show results 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 in the world 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).
