109 - Forensic Fire Science with Richard Roby

In this episode, we uncover the intricate process of fire investigations with renowned combustion scientist and fire investigator, Dr. Richard J. Roby from Combustion Science and Engineering. With over five decades of experience in the field, Dr Roby helps us navigate the critical role of the scientific method in fire investigations.

From the analysis of burn scars to the testimony of eyewitnesses, we explore the fascinating world of fire investigations, where data, evidence, and hypotheses come together to reveal the truth. We'll delve deep into the NFPA 921 standards, which keep fire investigations current with the latest scientific discoveries. We also delve into fire modelling, a tool that allows us to test different hypotheses and explain the spread of a fire. We also tackle the complexities of fire investigation and the crucial factors that can influence the process, such as expectancy and confirmation bias. Dr Roby provides invaluable insights from his vast experience, discussing the changing materials used in buildings and how they affect fire investigation processes. Finally, we explore the importance of recorded evidence and eyewitness testimony in fire investigations, and how to identify and understand biases to produce reliable results.

If you would like to learn more, I believe the best place to look would be NFPA 921, which you can find and access here: https://www.nfpa.org/codes-and-standards/all-codes-and-standards/list-of-codes-and-standards/detail?code=921
