Särkänniemi tries to be as safe as an amusement park can be. The rides have very good safety systems. For example, Tornado has two cylinders securing that the restraints stay closed, a safety belt holding the restraints down, a laser which watches that all the restraints are closed and employees securing and closing the restraints. The rides are also tested every morning before opening the park. At least Tornado's train is taken apart, secured and set up every winter. They have also secured the rides with ultrasounds. Employees are trained for disasters.
Of the rides, Jet Star has had some issues with safety in the past (lacking proper safety bars), but the trains on the ride have been replaced with new ones. The new trains are equipped with both, a locking lap bar and a grab bar.
