Process Hazards Analysis

Learn about the Process Hazards Analysis (PHA) *Hazard and Operability study technique with our proven SELF-PACED course featuring LIVE ONLINE sessions.

How do you prove that you have done enough about improving PHA and HAZOP team 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 PHA or HAZOP 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.
