Further information on descriptions Description: Aims:
The aims are:
* To increase awareness about the importance of ethical considerations and safety in the design and operation of process plant;
* To introduce techniques that can be used to make assessments of safety

Learning Outcomes:
After successfully completing this unit students should be able to:
* Make a formal assessment of risks and how to mitigate them on a given section of a process flow sheet using a HAZOP analysis.
* Evaluate hazards and assess risks by applying the concept of layer of protection analysis (LOPA).
* Describe the main safety issues of procedures outside normal operation, e.g. plant maintenance, start-up, shut-down and emergency relief.
* Recommend or not an investment in a plant modification to address an accident risk with environmental and safety consequences.
* Apply their ethical knowledge to quantify the environmental and safety impacts and the probability of occurrence.
* Apply a decision-making matrix to evaluate whether given project benefits are worth the financial outlay.

* Inherent nature of safety and principal hazard sources including flammability, explosivity and toxicity;
* Safety related legislation;
* Risk & hazard analysis, including HAZOP and HAZAN, LOPA, and other safety ssessment techniques;
* Safe practice including lessons learned from past incidents (e.g. Flixborough) and other incidents and accidents presented as case studies;
* Safe operations, including maintenance and work permits, flares, line purging.
* Contrasting decision-making frameworks within industry. Case studies and class discussion about fraud and tolerance to poor safety practices.
* The influence of workplace culture and relationships over ethical behaviour and decision-making.
* How to challenge poor ethical standards or practices in the workplace.
