On 22^nd May, Dr Ulises Rojas-Alva delivered an invited presentation on electric vehicle fire hazards in confined areas to the fire engineering and wider engineering teams at Transport for London (TfL).

The presentation addressed a challenge of growing urgency for one of the world's most recognised public transport networks. As TfL progresses with the electrification of its iconic red bus fleet, taxis, and other transit options, the fire hazards associated with lithium-ion battery technology are becoming an increasingly pressing concern for those responsible for the safety of passengers, staff, and infrastructure. Confined spaces such as tunnels, depots, and underground facilities present particular challenges, as they fundamentally alter the dynamics of fire development and the conditions that emergency responders face.

Dr Rojas-Alva provided an overview of the fire hazards specific to lithium-ion batteries and explained how these hazards transform traditional fire scenarios when they occur in confined areas. The presentation drew on FRISSBE's ongoing research in battery fire safety and EV fire risk, offering the TfL team a grounded, evidence-based perspective on the subject.

The Q&A session that followed was notably engaged, with the TfL team raising pertinent questions and contributing insightful observations that reflected the depth of their own operational experience. FRISSBE is grateful to Dr Carlos Walker-Ravena and the TfL fire team for the invitation and the quality of the exchange, and looks forward to the possibility of future collaboration.
