Course Description

People will always make mistakes when interacting with processes. That is the nature of humans. Fortunately, human errors can be anticipated and protective measures taken against their occurrence. This requires the application of human factors engineering. It can yield major benefits in risk reduction and improved operability for processes.

In this course you will learn how to identify the potential for human errors in processes and how to determine the human factors that control their likelihood. Types of human errors are described and illustrated with examples and the factors influencing human errors are discussed. Classification schemes for use in the identification of human errors are provided. The classical human-machine model is described and an improved person-process model is presented. Approaches to protect against human error are provided and their effectiveness discussed.

The techniques described are presented in a step-by-step format together with guidelines on how to perform the analyses. Examples are provided and attendees participate in workshop sessions to practice the techniques taught.


Provide instruction on how to perform human factors and human error studies to improve the effectiveness of plant design to minimize accidents.

Target Audience

Personnel with responsibility for safe process operations.


Prior experience or knowledge in process safety is useful.
