A lot of aviation accidents result in devastating fire. A fire in the air can destroy the airplane in a minute or two. If there's a ground accident, there's a darn good reason why the FAA requires evacuations within 90 seconds or something like that. Fire is the reason.
As I said, jet fuel is NOT safe. What we do is try to safely handle it.
For example, nobody in the industry is going to allow a lit cigarette anywhere near an airplane.
We have a lot of experience with jet fuel fires and have learned how they burn, how they start, how to fight them, and how to prevent them. We have very little experience with hydrogen fires. They may be worse, they may be better. We don't know.
