Every time I have comeback for a refresher I pick up something new. It’s always worth while doing this course every three years as the consequence of things going wrong is so great. A good refresher and I will be taking back a few point on how we carry out some of our operations.

I have undergone training for S5 at faradays for HV authorisation. It was really good & interesting. Throughout was session it was interactive, and I gained lots of practical experience for switching operations & issuing permits. Really appreciate the effort the lecturers have taken to explain the process for HV operations & safety precautions to be taken while working on HV apparatus. Overall experience was really good.
