Functional Safety 101 - Applying ISO 13849-1

Functional Safety 101

How to Apply ISO 13849-1 to Control Systems Design

Getting a handle on reliability

Functional safety has become a buzzword for many, but if you need to actually apply functional safety design techniques where do you start? Reading the standards doesn't tell you everything you need to know.

Certification classes are short, usually 4-5 days followed immediately by an exam, which doesn't give people time to fully integrate the ideas being taught, nor do the instructors have enough time to really dig down into challenging topics. If you are considering one of the functional safety certifications, ensure success by taking this course first.

Learn to apply ISO 13849 to the design of safety systems for machinery. This step-by-step course builds on your understanding of risk assessment and machine guarding based on the Hierarchy of Controls.
