Live online course – from 21 June 2022, 14:00–17:00 BST.

Quantified Risk Analysis (QRA) is the numerical combination of severity of consequence with frequency of event.

This online course will help you better understand different types of risk and how they are calculated. You will learn how to select scenarios to be modelled, and how to determine appropriate data as inputs.

The course explores the interpretation of risk results and how QRA can be applied to practical engineering solutions. It includes Occupied Building Risk Assessment and As Low As Reasonably Practicable (ALARP) demonstrations. Lectures are supported with practical exercises and discussion.

Teaching will be delivered via three sessions (approximately 2—3 hours in length each) and pre-recorded video content for independent study.

An e-certificate will be issued at the end of the course to confirm attendance and CPD hours logged. Please note that you must attend all modules to receive the certificate.

Learning outcomes

By the end of the course delegates will understand:

  • the definitions of risk
  • how to select cases to be modelled
  • how to build a QRA model
  • how to calculate risk and interpret the results.

Who will benefit

  • Managers, supervisors, engineers, safety personnel and others involved in commissioning and reviewing of QRA studies
  • Graduates, chemical and other engineers may find it beneficial in the preparation of the Chartered Member application

Course outline
