A circus needs to be bloody safe, because if it isn't it's bloody dangerous. Putting up a big circus tent is not an easy thing to do, and if it's not done right it could mean a horrible disaster. And then there's all the electrics...

Like any other building, but it has to go up dozens of times a year, in different places and different conditions, with different people doing the actual job. And a lot of them don't speak the same language.

I've always assumed that there is someone whose job it is to check that that kind of thing is done properly, and that this isn't just someone in the employment of the management.

The amazing thing is how rare circus disasters are. A very impressive record.
