Dreamworld Inquest: Questions Raised Over The Emergency Stop Button

Questions over the emergency stop button continue.

Amy Crisp, the supervisor who trained Courtney Williams, has been drilled over exactly how she trained the young operator hours before the fatal accident.

Crisp thought Williams had understood the emergency stop because she didn't ask any questions and she nodded in acknowledgment.

Williams was the co-ride operator on Dreamworld's Thunder River Rapids Ride on the day four people died in October 2016. It had been her first session on the ride.

The inquest heard Crisp did not demonstrate to Williams what happened when you hit  the emergency stop during her training.

Counsel assisting the inquiry Ken Fleming QC asked Crisp about the particulars of the training when it came to pressing the button.

"You weren't standing anywhere near it when you said that to her?" Fleming asked

"Not when we were at the main control panel no," Crisp responded.

Crisp herself has never seen the emergency button in action. When asked by Fleming if the "touching of that button wasn't encouraged was it" she said it was, in an emergency.

Crisp stood by the training. She said he had trained more than 60 hours on the ride and she said she knew her training was sufficient.

Crisp said when Peter Nemeth,  the senior ride operator, wasn't responding to the incident, Williams should have gone to the main control panel and shut down the ride.

"You say Ms Williams simply didn't do it properly?" Fleming asked.

"Yes" Crisp responded.

Crisp didn't know how quickly either the emergency button or control panel stopped the ride.

The inquest continues.
