I could see the lack of a limit. The performer is in control of their own movement, so that should be a non-issue. From what I gathered from the articles, she hit the
grid at a high speed which made the cable jump the
sheave which meant it hit a sharp
edge and was torn apart. In that case I'd question what made her hit the
grid (medical emergency, failure in the controller, and why an
e-stop wasn't initiated when she went off the choreography). That said, that doesn't really
line up with any of the earlier reports. If she fell while near the top of the wall, clearly she was not at the
grid.
Hopefully
OSHA and/or Cirque will publish the full report so that the industry can learn from this and hopefully prevent future tragedies.
Personal unsubstantiated opinion,
OSHA was trying darn hard to find something. Doubt there is ever a death without fines. She had been performing for years, obviously the accident was not caused by her lack of training in the
system.
