A second ride has been shut down at the Royal Adelaide Show after safety checks were stepped up following the death of an eight-year-old girl on Friday.

A second ride has been shut down at the Royal Adelaide Show, where an eight-year-old girl was tragically flung to her death.

The Royal Adelaide Show has closed the Traffic Jam ride in the Kids Carnival area after a height restriction breach was identified.

The safety breach was discovered on Friday, the same day an eight-year-old girl on holiday from Malaysia was thrown from the Airmaxx 360 ride.

She was rushed to hospital with critical injuries but died a short time later.

SafeWork SA officers increased the number of inspections and compliance checks at the show following the accident.

The agency said an investigation of the death was expected to take some time, given the nature of the incident, the number of witnesses involved and the technical expertise required.

Witness Malinda Dunwoodie, 17, said the girl’s safety harness was still on, but it looked as if she slipped out of her seat.

“She was hanging by her legs off the ride, trying to block herself. She went flying through the air about 10-15 metres up in the air and I started sprinting towards her,” she told News Corp on Friday.

“I was shaking so much, she looked like a doll flying through the air.

“It was so shocking. It was like a horror movie.”

The Airmaxx 260 was a new ride for the Royal Adelaide show this year, but operated at earlier shows in Sydney and Brisbane without incident.
