In general, the playing of classical music is not a particularly dangerous sport, at least not physically, but I have to tell you that the daily grind of the orchestra pit can take a toll on the health and well being of your instrument. You gotta be careful and plan for the worst! When we go on break, I generally try to place my stool strategically in order to dissuade folks from trying to step over the neck of the bass. Yes, they will try crap like that. And, should their toes catch the E-string, a whole chain of nasty events can ensue.
Have a productive weekend of shooting, everyone.
