No, the passengers were in a gondola off the bottom of the airship, the lift gas was concentrated at the top of the airship, some 100 feet above, above an asbestos ceiling. The real dangers were:

- being early in the days of flying. One airship disaster (the British R101) was the airship being extended, not tested carefully, and rushed into service for a political deadline. Another had the vents sealed shut so it hit its altitude ceiling. The Graf Zeppelin was one of the safest aircraft ever flown - a million miles without accident in the 1930s when aeroplanes were crashing a lot. Even the Hindenburg disaster killed 35 people, most of its passengers and crew survived.

- Using cow intestines stitched together by hand to make the Hydrogen lift cells. The stitching leaves holes which could let air mix with the lift gas.

- Many airship accidents were related to mooring, and having humans grab onto mooring lines and having humans try to pull a 7 million cubic foot balloon against the wind and that going wrong.

If we can now do high pressure Hydrogen powered cars, tanks of it in gas stations in urban areas and Hydrogen powered aircraft, and people think that can be safe, we ought to be able to achieve room temperature and pressure airship lift gas with it more safely than they could in the 1920s.
