Part of ride cycle: during ride
Category Description
Abrupt stop/drop/lurch

Injuries associated with an abrupt stop, drop, or lurch not described in the report as an e-stop, power outage or equipment malfunction.

Choking, water inhalation, suffocation

Drowning, near-drowning, choking, smothering, etc.

Collision: operator-controlled vehicles

Accidents caused by collisions involving ride vehicles that are not patron-directed (i.e., this includes coasters, log flumes, etc., but not go karts, bumper cars, etc.).

This includes entrapment while the vehicle is docking, but does not include entrapment while patron is entering or exiting the vehicle (i.e., misstepping into the gap between the vehicle and platform).

Fall (climb or play area)

Accidents involving a fall in an interactive play area (slide, climbing structure, wet play area, etc.).

Fell from seat, but not carrier

Patron fell out of the seat, but did not fall completely out of the carrier, either because the ride has enclosed carriers or the patron fell onto the floor of the carrier and the ride's motion did not further dislodge him/her.

Fell or slid out of waterslide or snowtube

Equipment failure

Any accident where equipment failure contributed significantly to the injury and the event did not fit into any other category.
Note: Equipment problems may also cause or contribute to accidents in other categories.

Category Description
