Functional Safety Training

PM PROjEN can provide a two day Functional Safety training course which is essential  for anyone who is involved in Safety Instrumented Systems (SIS), particularly from a plant owner/operator point of view. After the key principles of functional safety are introduced, the participants are guided through the SIS lifecycle from BS EN 61511 so they understand the end users responsibility when it comes to relying on these programmable electronic safety systems to control the risks on site.

An overview of the legal framework and current and standards is provided together with the requirements for management of functional safety. Participants are also made aware of the essential features of SIS design that make it suitable for a given application, in order to understand how to maintain the safety integrity during the operational life of the system.

An optimum blend of presentations, case studies and worked examples is used to ensure a rewarding learning experience for each participant.

Day 1

1. Introduction to safety instrumented systems:

  • Hazards, risks and risk reduction
  • Examples of safety instrumented functions (SIF)
  • Safety Intregrity Levels (SIL)
  • How safety instrumented systems (SIS) can fail
  • Legal and regulatory considerations
  • Overall functional safety objectives.

2. Functional Safety Standards

  • Overview of BS EN 61508 (context and generic)
  • Overview of BS EN 61511 (process industry)
  • The safety lifecycle approach
  • Latest publications

3. Hazard and risk analysis (appreciation)

  • Identifying specific hazards (HAZID, HAZOP)
  • Tolerable risks, corporate criteria and ALARP
  • Risk reduction and allocation to the SIF(s)

4. SIL determination 

  • Determining SIFs and their SILs
  • Overview of Layer of Protection Analysis (LoPA)
  • Overview of Risk Graph
  • Other methods

5. Safety Requirements Specification 

  • Required parameters for each SIF
  • Specifying the SIS
  • Importance of traceability and verification

6. SIS design essentials (appreciation for the user)

  • Probabilistic and systematic failures
  • Technology and PLC platform considerations
  • Application software considerations
  • System architecture and elements
  • Demand modes and SIF probability of failure
  • Behaviour on detection of a fault
  • The design file and user documents

7. Installation, validation and commissioning 

  • Procedures for these lifecycle phases
  • Verification

8.Operation and maintenance

  • O&M Procedures
  • Proof testing
  • Spurious trips
  • Logs and audits.

Day 2

9. Functional safety assessment (FSA)

  • Planning, assigning and documenting FSAs
  • Scope of FSA stages 1 to 4

10. System modifications

  • Modification control
  • Impact on other lifecycle phases and assumptions
  • Approval and re-validation (FSA 5)

11. Functional Safety Management (FSM)

  • Safety management policies and procedures
  • Roles and responsibilities, documentation, competence, corrective actions, suppliers, etc
  • Audit and management review

12. Competence Management

  • Considerations for setting up a (practical) competence management system

13. Roundup of the SIS lifecycle, terms and abbreviations

  • Review of the SIS lifecycle and phases
  • Ensuring lifecycle continuity between phases
  • Key terms used and their meaning (verification, validation, audit, assessment, etc)

14. Example Case Study

  • An interactive walk through of a typical project following all the topics covered in the sessions above
  • Discussion Points, Q&As

15. Course Review

  • Review of learning outcomes
  • Final Q&As
  • Feedback.
