I know and agree about hydrogen. I have worked on many projects where systems are isolated (valving is used to isolate sections of pipe in order that work can be performed), locked out an tagged out.

I worked on a project in Industrial gases where tanks were erected and tied in to an operating plant. It was an oxygen plant, which is even more explosive than hydrogen. We were looking for a shutdown window to do the tie-in. I really doubt that they flushed all of the oxygen out of the piping for the whole plant in order to do the welding for the tie-ins. That would be ridiculous..

I could research this. I think it would be fairly easy to establish that such things are possible.
