169 - Engineering car parks for EV's with Ali Ashrafi and Pawel Woelke

Fire Science Show

EVs are becoming more of a 'normal' part of fire safety engineering rather than an 'exotic problem'. I've invited two colleagues from Thornton Tomasetti - Ali Ashrafi and Pawel Woelke, to discuss what this engineering looks like.
In the episode, we discuss insights into how fire risks differ between electric and internal combustion engine vehicles and why the focus is shifting from cars to more pressing hazards like electric scooters and energy storage systems. We explore the different approaches in the US and Europe, discussing the importance of performance-based solutions and timely detection to manage fire risks effectively. W We'll also discuss the critical role of ongoing education and adaptation in the fire safety industry as technology evolves.
An important aspect is the practical strategies for mitigating fire spread and explosion hazards in vehicle design and parking facilities. From the significance of separation distances and sprinklers to the potential dangers of gas accumulation, our conversation dives deep into the intricacies of ensuring a safer environment for both people and property. We also highlight the importance of early planning and thoughtful design in integrating EV infrastructure into building designs, and how real-world incidents shape our understanding and approach to EV safety.
