Having been a first responder to a fire in a shopping centre sub station/transformer where a technician lost their life in the incident, I do have a limited amount of experience around transformer fires, and I don't necessarily see my comment as 'fear mongering'. Particularly when the context is the question the person above me asked (failure modes of large substations). Under normal operation they are safe, and in abnormal circumstances they can catch on fire.
