The accident occurred on a spinning ride at a park in the Wolmido area. The rider was thrown clear of the ride, sustained injuries and was taken to hospital.

The ride spins a disc on which passengers sit, with an operator controlling speed and direction. Because riders hold on to handles and the wall rather than wearing belts, both posture and operation affect safety.

Authorities are checking the ride's periodic inspection record and whether operating staff followed safety rules. Inspection intervals and standards vary by ride type.

Wolmido is easily reached from central Incheon and draws many family visitors, forming a tourist route together with the nearby Chinatown.

Accidents at amusement facilities can arise from how a ride is operated as well as from mechanical faults. Checking the posted guidance before boarding, and not riding when unwell, is advised.
