In this week's series covering experimental fire science, we venture into a recently finished Code Red project by ARUP, led by my today's guest Dr Panos Kotsovinos. The project was carried out in CERIB with the collaboration of the Imperial College London. History will tell if this experiment will change fire science, but I truly believe it is at least worth sharing!

The research was carried out on a large open-plan office (350m2) with a combustible CLT ceiling. It was a continuation of previous X-One and X-Two experiments on travelling fire behaviour carried out by Imperial College London in Poland (referred to here as the "Obora" experiments, listen to episode 27 of the show) but with an important difference - this time the ceiling was combustible. They were looking into how the introduction of the combustible ceiling will change the travelling fire behaviour, investigating variables such as the opening factor, the introduction of a low-pressure water mist system and partial encapsulation of the ceiling. The findings include observations related to fire spread, persistent smouldering fires, effects of the partial encapsulation and many many more which are discussed in detail in the show.

To learn more, please read the press release about the experiments here and most important - the papers:
- Fire dynamics inside a large and open-plan compartment with exposed timber ceiling and columns: CodeRed #01
- Impact of ventilation on the fire dynamics of an open-plan compartment with exposed timber ceiling and columns: CodeRed #02
- The Effectiveness of a Water Mist System in an Open-plan Compartment with an Exposed Timber Ceiling: CodeRed #03
- Impact of partial encapsulation on the fire dynamics of an open-plan compartment with exposed timber ceiling and columns: CodeRed #04
- Review of fire experiments in mass timber compartments: Current understanding, limitations, and research gaps
- Structural hazards of smouldering fires in timber buildings
- Flame spread characteristics in large compartments with an exposed timber ceiling

If you have any further questions to Panos please let me know, and I will gladly pass them on to him!
