What is in the pipeline that may present even bigger hazard than the electrical issues shown?

Which line was there first?

Use of welded flanges instead of threaded couplings or compression unions suggests that it not as simple as sprinkler, water, or waste.
Also pretty big pipe.
That notch comes pretty close to where gasket or O-ring would be,

That sort of flange usually has gasket same size as the flange. they are missing nearly half the width at that cutout point.

Most places I have been in that have process piping have some kind of inspection process. If it is just water no one cares but if it is some kind of chemical the insurance company generally wants some assurance that the piping was done correctly.
 
As tight as the two LB’s are against the pipe flange, I would say the LB’s were there first. It would be tough to get them in there without a hammer. No grind marks on the bolt, unless they took it out while grinding. Probably a sprinkler main.

Many large flanges are “raised face” - the gasketed surface is a diameter that is smaller than the bolt circle. Provides greater clamping force on the gasket. That’s likely the case here, looking at what appears to be a gap between the visible part of the joint.

There isn't enough space between the bolt circle and the pipe for a raised face flange. My guess is they wedged the pipe away from the wall, installed the LB's, notched the flanges, and let the pipe swing back. Might have taken a time or three to get the notch big enough.

Lol
Did you try to swing pipe like this and fool around with lb install wiring and ...
I would not try.

You can see the strap on the bottom of the pipe, so it's hanging not, in a cradle. Set up a jack against the wall on a 2x4 to spread the load and push the pipe away. Would probably need 2 jacks to prevent jackknifing the joint. Then some built up 4x4's to whatever thickness you need, lower the pipe to rest on them, and away you go.

I’m with Hal as he posted in #4.
There’s not an electrician around that would attempt that as easy as it would be to reroute the electrical pipe and put the LBs somewhere else.
