Description

In this show, we have already ventured into the fascinating world of toxicity in fires, and I have promised you more. So today, I fulfil my word and invite you to another conversation with renowned fire toxicity expert Professor David Purser, who shares invaluable insights on measuring smoke and toxic products created in fires. From understanding mass loss concentration in a CFD analysis to exploring various test apparatus, discover how we can determine the yields and concentrations of toxic products in different fuels and conditions. Learn about the significance of the fuel/air mixture ratio (the equivalency ratio) and the need for defined combustion conditions to measure toxic product yields accurately. On a practical side, you will learn about prof. Purser's experience working on the Mont Blanc tunnel investigation, where he used CFD analysis to study toxic product concentrations and yields in real-life fire scenarios. Professor Purser emphasizes that while exact solutions may not always be available, science and research can provide valuable insights into the toxic effects of fires.Another, final episode on smoke toxicity with David Purser coming out next week.
