 Session 1 – PROCESS SAFETY – 60 minutes

 The course starts with a review of how modern PS has evolved in relation to industrial development and changes in society’s values, illustrated by reference to some major international disasters (Flixborough, Seveso, Bhopal, Longford, Texas City and Piper Alpha). Delegates will learn about the underlying causes of these accidents and how defence in depth is necessary to avoid them. Common terms used in PS will be defined.

  • Development of process safety
  • Historical incidents
  • Causes of accidents
  • Key definitions, e.g. hazard, risk

Session 2 – HAZARD AWARENESS  – 30 minutes

Hazards can arise from the process materials, the equipment design, upset conditions and operational activities. Examples of each are described and measures to avoid or control them are discussed. The learning outcome will be a comprehensive knowledge of the range of possible hazards. Topics include:

Session 4 – RISK MANAGEMENT – 220 minutes

Delegates will learn how process hazards are managed systematically throughout the life of an asset, with particular emphasis on the design stage, using the 5-step risk management approach. The concepts of individual risk, societal risk and risk criteria will be explained with reference to the ALARP Principle of risk tolerability. The use and limitations of semi-quantitative risk matrices to analyse risk, will be discussed. The application of QRA will consider escalation, sensitivity analysis and rulesets and discuss its limitations as an absolute measure of risk.

Exercise:        A RBDM framework is used to examine the trade-offs between technological and value-based decision criteria in a case study concerning options for reducing benzene emissions during loading of gasoline onto a ship.

Session 5 – HAZARD IDENTIFICATION – 240 minutes

 The purpose, resource requirements and methodology of each of the common techniques will be explained. Delegates will understand how HAZID and HAZOP are used at different stages of a project, and will undertake HAZOP exercises to illustrate its application to a continuous operation and a critical manual draining procedure.

HAZID is used to identify general health, safety and environmental issues arising due to installation, construction and maintenance activities, and those arising from the environment in which the plant operates. 

FMEA is similar to HAZOP but is used to identify the effect of equipment failures in mechanical and electrical systems. Delegates will learn how it can be applied to equipment functions as well as to equipment hardware.  

A Bowtie diagram is a visual overview of multiple scenarios in a single picture, showing the relationship between causes, consequences and barriers.  It is readily understood by non-technical people and so can be used to quickly identify alternative safety strategies if a barrier fails.

At the end of this session, delegates will be able to select appropriate hazard identification techniques, and how to organize and conduct them properly, and understand the relative contributions that HAZOP and HAZID can make when used together.

  • Hazard & Operability study (HAZOP)
  • Defining the scope, boundaries and nodes
  • Selecting appropriate guidewords
  • Protective measures
  • Use of Cause and Effect / SAFE charts

  • Process safety design activities and deliverables
  • Risk-based design approach
  • Limitations of codes and standards
    • Inherent Safety, including video of explosion at Bayer Crop Science

The concept of safety critical elements based on major accident hazards and the need to develop performance standards for them during the project design phase will be explained. Once a plant is in operation, many of the design performance standards no longer apply or need to be verified. However, different requirements may apply so operational performance standards are developed in a format, which recognises that corrective and/or compensating actions are necessary when performance deteriorates, e.g. if a fire pump fails its regular function test.

  • Major accident hazards

Session 8 – FUNCTIONAL SAFETY – 180 minutes  

Functional Safety is the correct functioning of safety instrumented systems (SIS), alarm systems and basic process control systems (BPCS), which provide a significant level of risk reduction against accident hazards.  They typically consist of sensors and logic functions that detect a dangerous condition and final elements such as valves that are manipulated to achieve a safe state.

The concept of safety integrity and how target availabilities of safety instrumented systems are set will be explained.  The use of LOPA to justify the level of protection for given hazard scenarios will be described using a case study and the means of verifying that the instrument architecture meets the target availability will be outlined.

Session 10 – HUMAN FACTORS – 150 minutes

The underlying reasons for various types of human error will be highlighted with the use of a video case study. Reasons will be given why, during the project design phase, there is normally insufficient information to apply the standard method of assessing HF. Guidance will be given for how it should be considered during HAZOP meetings, and on particular aspects of design issues such as ergonomics and alarm management. At the end of this session, the delegates will understand how maloperation and poor maintenance can give rise to safety hazards, why plant operability is important for safety, how systematic humanware failures can occur and be able to analyse critical tasks.

DAY 5

Session 14 – Syndicate Exercise : Process Safety Management – 340 minutes

Process Incident at Rollrite Steel     

The course will conclude with an extended case study of process safety management in an industrial facility. The study concentrates on preparatory activities prior to making relatively simple modifications to external instrumentation on a pressure vessel containing an apparently non-hazardous fluid. The groups have to organize themselves to pursue several lines of enquiry at the same time, separate material facts from a large amount of, sometimes conflicting, information, and draw upon much of their course learning. 

The study is broken down into four progressive stages, each lasting approximately 80 minutes. At the beginning of each stage, the groups receive a management briefing and are challenged to form opinions from the information they have received.  Each group can ask a limited number of questions at each stage, and the trainer’s replies will be given to all the groups during the briefing at the beginning of the following stage.

 

Stage 1:      An assessment is made of the procedures and permits in place to control the relevant operational and engineering tasks, how change is managed in the company and the adequacy of the task risk assessment employed. 

Stage 2:      The groups are asked to review the system design and its operation, and opine on the appropriate process hazard identification method and how this might be organised.

Stage 3:      The groups are informed that a process incident occurred during preparation for the modification work and two workers died. They are given the timeline and sequence of events, witness statements and investigation reports, and they are asked to identify the likely cause.

Stage 4:      Each group will present a verbal report on how the incident could have been prevented with recommendations for changes in management procedures, working procedures, equipment design, training, organisation, etc.

                   Feedback and inter-group discussion (20 minutes).

 

Session 15 – Course Assessment, Feedback, Q & A – 20 minutes

 The trainer will summarise the objectives of the course and explain the relevance of all sections of the course. Delegates will be encouraged to give their opinions on the course so that the content can be continually improved.
