How do you prove that you have done enough about improving LoPA competence?

You may have had the dreaded visit from the regulator or insurers that means you need to improve team competence. You may be an individual tasked with joining a LoPA study. Either way, we can help by providing traceable online learning.

Competence is difficult to demonstrate. Send someone on a course for a week, and what evidence can you show to a regulator or insurer - a certificate of attendance?

Is a certificate of attendance enough to demonstrate to yourself or someone else that you are now competent with a new skill or topic area? Surely not.

We believe that too many of today's face-to-face and online courses are simply not challenging people to think. There is a "tick-box" mentality to gaining an attendance certificate.

Our online training is different - it challenges the individual to think and to demonstrate their knowledge as they progress.

*Layers of Protection Analysis - LoPA - for SIL Analysis

How to ensure your SIL Analysis team is doing a good job? Do you have the right knowledge to judge if you are doing enough to comply with the latest functional safety standards IEC 61511 and IEC 61508?

The fact is, you need up to date information from someone who has applied the standards in practice. For people without much experience in this area, determining precisely how much effort to put into each phase of the safety life-cycle can be a daunting prospect.

This course eliminates any confusion surrounding Layers of Protection Analysis. You’ll learn key principles and concepts in a way that enables you to apply them to any project.

The course starts with a review of key terminology and the safety life-cycle and then expands on the detail of LoPA for assessing independent protection layers (IPL) and safety integrity level (SIL) targets.
