Introduction to Functional Safety | E-learning

The Introduction to Functional Safety e-learning course was developed by ESC experts in partnership with the IET – The Institution of Engineering and Technology.

Introduction to Functional Safety | E-learning

The course is based on ESC’s Introduction to Functional Safety 1 day training course but with a more in-depth look at the concepts and requirements of the international standard IEC 62508. 

The advantage of the E-learning course is that the participant can go through the course at their own time and pace providing a sound basis for anyone involved in the management, specification, design, system integration, operation, modification, and maintenance of safety-related systems.

Course Learning Modules

The course comprises of 11 Modules. An illustration of some of the learning points in the course are listed below:

  • Understand the course is based on the concepts and requirements of international standard IEC 61508
  • Understand the concept of functional safety and its relationship to safety
  • Understand the terminology relating to systems and risk concepts
  • Understand the overall system architecture comprising the Equipment Under Control (EUC), the EUC Control System and the Electrical/Electronic/Programmable Electronic (E/E/PE) safety-rated system
  • Understand the concept of Safety Integrity Level (SIL) in the context of Electrical/Electronic/Programmable Electronic (E/E/PE) safety-rated systems
  • Learn about Multiple Layers of Protection & Mitigation
  • Understand the role that the SIL of a safety function plays in achieving the Target Risk
  • Understand the concept of Safety Lifecycles and the role they play in the achievement of functional safety
  • Learn about the System Safety Requirements Specification and the System Design Requirements Specification
  • Understand what compliance to IEC 61508 means
  • Understand the concept of Safe and Dangerous Failures in the context of Safety Functions
  • Learn about Random Hardware failures and Systematic Failures
  • Understand how Hardware Safety Integrity is achieved
  • Learn about how the Target Failure Measure for the safety function is calculated based on random hardware failure data
  • Learn about the sources of random hardware failure data
  • Learn about Proof Testing of safety functions
  • Understand the concept of Architectural Constraints and its role in the achievement of Hardware Safety Integrity
  • Learn about the key parameters that determine the maximum SIL that can be claimed for a specific safety function
  • Understand the concept of Systematic Safety Integrity and Systematic Capability
  • Learn about the design requirements to achieve the Systematic Safety Integrity for E/E/PE safety-related system in respect of a specified safety function
  • Understand Assurance Measures comprising: Verification, Validation, Functional Safety Assessment and Functional Safety Audit and the role of independence plays in the application of Assurance Measures
  • Understand the role that management plays in the achievement functional safety Learn
  • Learn about some of the key requirements in management of functional safety including competence
  • Understand the concept of As Low as Reasonably Practicable (ALARP) in the context of E/E/PE safety-related systems
  • Learn about Cost Benefit Analysis (CBA) and the role it plays in the ALARP demonstration

Who will benefit

This course is suitable for technical staff, and managerial staff managing functional safety, or involved with, the specification, design, system integration and maintenance involving complex E/E/PE safety-related systems.


We have developed a workbook to go alongside this E-Learning course.  It comprises of:

  • A copy of all the slides that are shown on the screen; and,
  • All the text of the voiceovers of the slides; and,
  • A section where you can make your own notes (through an editable PDF)
