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.

After a long period of only being able to offer online seminars, we were extremely pleased to have held our first face to face series of seminars earlier this year.  Due to their success, we would like to announce that our November series will now take place in Oxford!

We will be at the Kassam Exhibition and Conference Centre on the 14th - 16th November 2024.

Our SIL seminar will take place on the 16th November, typically 9am - 4pm. 

It will get busy, so try and book your place/s early!

**You will also have the opportunity to book a place/s on our ATEX, taking place on the 14th November and our Advanced ATEX, taking place on the 15th November**

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

"Could you please pass on my thanks for an excellent day yesterday", SB

"I just wanted to send a quick email to say thanks for the superb training seminar yesterday especially to Michael who was an excellent teacher, I have certainly gained a lot of valuable knowledge" TM
