I would prefer the stage shown BELOW over most that I have ever been on. It look's to me like the entire structure was well designed and well built with plenty of bracing and support. The scaffolding also appears to be assembled properly. Pretty nice stage if you ask me. (Thanks Mac.)
Disclaimer: I AM NOT A RIGGER OR STRUCTURAL ENGINEER and I am not trying to pick on anybody, just making some observations.
At first glance this looks good, but I noticed a couple of things I would question, although hard to tel l from the picture:
Outriggers are not installed with cross bracing. Usually they are installed in line with the frame, not diagonally as show.
The truss suspending the PA is resting on the top tube of the scaffold. Suspension of anything like that is supposed to be on a structural metal saddle beam that transfers the force to the vertical tubes of the scaffold.
I cannot tell from the picture if it is done, but the truss beam also needs to be secured so it cannot move.
It also looks like the towers are guyed off to the upright support posts of the roof.
Will it fall over? Probably not. Is it safe? I guess that depends on the situation.
Could it be better? Probably.
I personally like the idea of drawings and plans approved by somebody with more knowledge than me. Storms take down buildings, any temporary structure we build is going to have limits. I would like to know what they are.
Bad rigging is all around us, I found some today in one of my facilities. I have to erect towers for many events I deal with. I am on my vendors and my facilities people about what are limits are. I also hire an independent rigger as my eyes and brain to keep on eye on things that I might miss.
Organizations like the Event Safety Alliance http://eventsafetyalliance.org/
are going to be very helpful as our industry moves forward. It is definitely a dialog that needs to keep going. I for one, would like to see a whole safety category on here to keep abreast of best practices in all areas not just rigging. ( I saw a bad electrical issue to today too!).
