Are the pool noodles your air supply system?

the lumber that rests on the angle iron is meant to resist lateral pressure. Often the gap is so large they can shift. The noodle (or spray foam) keeps them in place. That's probably going to be in a technical addendum to the Idaho Dept of Mines handbook.
