Technical presentations

Our programme features over 80 presentations from industry practitioners, researchers and regulators. They will share examples of good practice, new approaches and valuable lessons learned in process safety that you can transfer to your own operations, and address some of the future challenges and opportunities facing the industry.

Plenary speakers

The technical presentations are complemented by our inspiring plenary speakers who will present on the themes of embedding good practice, leadership, emerging challenges and the importance of cross-sector learning.

This includes the Trevor Kletz Hazards Lecture, delivered this year by Dame Judith Hackitt who is always an engaging and thought-provoking speaker.

Facilitated discussion

There will be time for questions at the end of each presentation. There will also be facilitated discussion time at the end of each session, to help continue the conversations, identify common issues facing practitioners and encourage networking.

On-demand recordings

Technical presentations will be delivered across parallel sessions on 18–20 October and it isn't possible to listen to all the content at the event. Conference attendees will be able to access video recordings of the presentations after the event, to catch up on ones they missed or revisit content that interested them most.

This was a popular feature of our virtual conferences and we are pleased to incorporate it as part of our in-person event.

Workshop: Bowties Making Sense of Safety

Wednesday 18 October, 10:30–12:30 BST

Process Safety: Keeping the Peace in a Post War Age
Angus Keddie, Process Safety Matters, UK 

The war on process incidents has been raging for 200 years. As processing facilities evolved, the hazards they contained mutated, becoming bigger, more toxic and more energetic. As the hazards advanced, we improved designs, developed more robust barriers and reshaped culture. By first decade of the 21st century, the hazards appear to have been subdued – as far as reasonably practicably. So, if, finally the war has been won, how can we now best keep the peace?
