OSHA announced Oct. 29 that six citations were issued to the Montreal company because they did not provide proper training for the performer or properly assess the workplace for hazards.
Fines to Cirque du Soleil could total more than $25,000.
OSHA is also planning to issue three citations against the MGM Grand, where the performance of KÀ took place. The hotel said it will also appeal the citations.
Following the June 29 accident, performances resumed July 16; that performance was dedicated to the memory of Guyard-Guillot.
According to an earlier press statement from the Clark County Office of Coroner/Medical Examiner, "The manner of her death was accidental. The Nevada Occupational Safety and Health Administration (OSHA) is continuing the investigation into how this accident occurred. The OSHA investigation could take up to six months to complete."
"I am heartbroken," said Cirque du Soleil founder Guy Laliberté in a previous statement. "I wish to extend my sincerest sympathies to the family. We are all completely devastated with this news. Sassoon was an artist with the original cast of KÀ since 2006 and has been an integral part of our Cirque du Soleil tight family. We are reminded, with great humility and respect, how extraordinary our artists are each and every night. Our focus now is to support each other as a family."
Guyard-Guillot also taught at a school called Cirquefit, a Las Vegas program for children. Donations are being accepted for "the children's future" and can be made at ForSasoun.com.
