Our sets in the outdoor amphitheater are unique. They are large and semi-permanent. We build them to be wind resistant but nothing is wind proof. The turntable is very useful and adaptable. If the wind is blowing hard enough to move the turntable, you are probably safer to get away from it. Everything to do with the set can be somewhat dangerous, though. People can get run over by a moving turntable.
The concrete stage has various levels that might present a tripping point or turn an ankle if you don’t anticipate the edges correctly. Doors blow open or shut in the wind. Splinters from the wood are rampant and wasps love all of the wood for nest building, not to mention all of the open pipes where they can be built.
