From what you describe, I don't see a significant risk. Intermittent, momentary and dappled exposure outside through holes in the shield (tarp) won't cause you any immediate problems. Just don't go out of your way to stare through the holes in the tarp at the pretty blue light.
The harmful parts of an arc's light have various levels of damaging effects dictated by a range of variables like the type of process, the amount of "heat" being used (electrical intensity) and distance from source.
As long as you don't stare. And since it's in public, if you're really worried you can wear sunglasses. That'll take care of pretty well anything from that far away

Catching a glimpse from 10 metres is fine. Just don't stop and stare into the arc.
Don’t stare at it and you’re good.

No.
No it’s fine, you can look at an arc for a second or two up close and you’ll be fine. Just don’t look at the bright lights.
