I mean for the most part we did figure out how to fly with hydrogen above our heads. The 1/3 of the occupants of the Hindenburg than did die (the remaining 2/3 survived) died because they couldn't escape the wreckage _on the ground_. I do think the more accurate thing to compare to are diesel submarines. A fire there is going to be even worse than one in a zeppelin (unless that zeppelin is over the ocean).
