HF 10 – Human Factor in Barrier Management Level 2 (Focal Point)

Course Overview

The concept of layers-of-defenses or multiple barriers to protect against major risk applies to every aspect of business that carries significant risk. “Barrier Management” refers to the process of assuring barriers expected to protect against major losses are actually established and effective. In recent years, the technique of Bowtie Analysis has become popular as a simple and convenient means of identifying barriers, understanding how they can fail, and what needs to be done to assure they are in place and reliable. Bowtie Analysis is used in the chemical industry, O&G exploration and production, air traffic, nuclear power and others. It can be applied to enterprise risk and operational risk.

Barriers frequently rely on people to perform functions (detect, decide or act), or to inspect, maintain or perform tests to ensure barrier systems are in place and functional. Errors in decision making, risk assessment or operating, maintaining or testing automated systems can cause barriers to fail.

This training reviews the role of people in barrier management systems, providing an in-depth understanding of expectations and intentions organizations often hold of people in ensuring barrier performance. It demonstrates best-practice in assuring HF in Barrier Management systems.
