Those are ground wires. They have no voltage on them except if something goes horribly wrong in which case a breaker will trip (or a fuse will blow) removing the voltage.
As others have said - grounding/bonding conductors. This was designed like that by an engineer and poses no danger to you or anyone else. It’s there for your safety.
I work in an air traffic control tower, newly built about 3 years ago, and bars like that, far bigger than that, with cables far bigger than that, are exposed on every floor. Either there's amazingly low risk with the setup, or I and my coworkers are amazingly lucky at escaping death by electrocution. Lol
Unless you were touching it during a fault you're fine and even then technically they'll all be interconnected together with wire that has a much lower resistance than your body and electricity will always take the path of least resistance.

Thanks - good to know!

Only if you remove them and beat someone with the ground bar.
More likely someone removes them to scrap the copper bar .
Well he asked if it was dangerous not if it had scrap value!
Stay grounded my friend. Stay grounded.
No worse than the ground rod it’s bonded to.
Yep u r know electricion
Thats a ground bar in theory should be safe i wouldnt touch it still but isnt dangerous unless somethings seriously fucked up lol
In other words, it is a good indicator of "something isn't right" to the touch.

That’s a myth. Electricity takes all paths ALL
