Functional Safety (SIL) Training

Risk is an integral part of our daily lives. Hazards are also present in our working environment. Thus, it is important to identify anything that could pose a risk of death or injury and to eliminate any hazards at work emanating from production processes.

EN 61508 sets the basis for the planning, set-up and operation of electrical and electronic protection measures. The goal of the seminar is to give an overview of the fundamental principles and methods, the most important terms and definitions, and how to interpret them.

We are running our face2face seminar for SIL on the 14th November 2024, typically 9am - 4pm, at our Head Office in Oldham (Pepperl+Fuchs GB Ltd, 77 Ripponden Road, Oldham, OL1 4EL)

Places will be limited, so try to book early to avoid disappointment!

**You will also have the opportunity to book a place/s on one of our ATEX seminars, taking place on the 12th November and our ADVANCED ATEX, taking place on the 13th November 2024**

The program targets management, engineering, production and safety personnel involved in equipment design and use, where potentially explosive atmospheres are present.

"I’m  just back from the SIL Training seminar in Aberdeen and just wanted to say how good it was.

The presentation and material covered were excellent and your training representative was extremely informative and engaging.

I will be recommending these seminars to my colleagues". Kate Gray

"The feedback from all has been excellent so a big thank you to Michael and all the team", AC
