In a nutshell

What this course aims to achieve

Understand the principles, advantages and limitations of the APR and HAZOP methods to identify and prioritise accident scenarios at an industrial facility

Two days practising the two risk analysis methods most used in the process industry: preliminary hazard analysis to sweep broadly at an early stage, and HAZOP to examine an installation line by line once its design is settled.

Key challenges

  • A HAZOP started too early stalls on incomplete drawings; started too late, its conclusions arrive when changes cost ten times more. When the study is run determines its worth.
  • A HAZOP session invariably drifts into problem-solving: it is the facilitator's job to bring it back to identification, otherwise half the nodes will never be examined.
  • Existing safeguards are recorded as given, without checking that they are tested and maintained. An analysis resting on a failed safeguard overestimates how well the scenario is controlled.

Learning objectives

  • Choose between preliminary hazard analysis and HAZOP according to the project stage and the nature of the installation
  • Prepare a session: division into nodes, documentation, composition of the team
  • Run the study using the guide words and their associated deviations
  • Identify causes, consequences and safeguards, and rank the scenarios
  • Write minutes that can be acted on and follow up the agreed actions

Detailed programme

  1. 1Where preliminary hazard analysis and HAZOP sit in the industrial risk control process
  2. 2Preliminary hazard analysis: hazardous elements, undesired events, ranking
  3. 3HAZOP principles: study nodes, parameters, guide words, deviations
  4. 4Preparation: piping and instrumentation diagrams, node division, documents required
  5. 5Composition and facilitation of the working group: roles, session length, fatigue
  6. 6Causes, consequences, preventive and protective safeguards
  7. 7Ranking scenarios and linking them to the hazard study
  8. 8The limits of both methods and when a quantitative analysis becomes necessary
  9. 9Practical HAZOP sessions on a worked installation

Target audience

  • Process, project and maintenance engineers and technicians
  • HSE managers and safety engineers on industrial sites
  • Future facilitators of risk analysis groups

Prerequisites

  • Knowledge of an industrial process and the ability to read piping and instrumentation diagrams
  • Engineering or higher technician level background

Learning methods

Two days face-to-face, half the time spent in analysis sessions

A worked installation supplied with its complete drawings

Learning assessment

Facilitation of an analysis session observed by the trainer

An analysis report produced as a group

Scope of application

Recognised analysis methods, used in particular in hazard studies for regulated installations and in determining required safety levels. The course teaches the methods; it does not constitute a hazard study, which is an engineering exercise on the real installation.
