About us

Functional Safety is a multi-faceted subject that requires a thorough understanding of the factors involved and how they interact with one another to help minimise the risk of failures caused by operator errors, hardware failures and environmental changes.

Created by ABB's Safety Lead Competency Centre (SLCC), this blog covers the key challenges and considerations involved in the design, operation and management of functional safety systems in industrial applications.
