I would settle for a single, clearly demarcated pair of doors to the dome that will be opening, and a queue enclosed by a rope barrier or something that's long enough for a few thousand people to queue up.

Most of the safety hazards are caused by later-arriving teams skipping straight to the front and pushing through, and the crunch into the escalator and staircase since they are a bottleneck after too many doors are opened.
