Have you all watched the video of the recent circus accident ? Whatever attachment they had in place obviously was not designed by a competent person, nor installed by a competent person as OSHA requires.
I am pretty sure OSHA does not allow the worker's PFAS to be installed to the equipment they are standing on., and the dancer below was not wearing a hard-hat, nor were any of the acrobats. It just seems so obvious, that there was no backup system in place in case of failure. I bet the circus act designer's emphasis on portability and reduction in weight were factors in the faulty design. It will be interesting to see if a pin came loose, or there was a fracture in the main link. Somewhere there is a personal injury attorney with a big smile on his face. David Locklear
