using the system is instructed how to use it and display a copy of the signal code in appropriate

positions;

— ensure that emergency procedures are established, well documented and regularly practiced;

— provide full instructions on the control or communications system.

The ride controller can delegate any part of his duties, but remains responsible in law.

Adequate training shall be provided to all employees and training records kept. Training shall be

appropriate to the risks and given in a way that those being trained can understand.

The operator and attendants of amusement devices shall demonstrate competency in the operation of

amusement devices according to the manual(s).

No operators or attendants of the amusement device shall be younger than required by national

standards or law in the country of use.

Operators and attendants depending on their duties, shall be provided with suitable and sufficient

information and training in the working of their amusement devices, covering:

— systems of work for safe operation, including speed limits and any other specific safety measures;

— procedures for reporting breakdown, defects or unusual occurrences;
— loading and unloading procedures;

— passenger restrictions such as height and weight limits, medical conditions, limited accessibility

The ride controller or his representative shall ensure that an amusement device is only sited on ground

which is suitable for this purpose in accordance with the manual(s). For example ensure that the

ground:

— can safely bear the load of the amusement device. For existing structures e.g. buildings or piers, a

detailed inspection and calculation shall be carried out in order to establish permissible loads;

— is sufficiently flat, even and stable for the attraction to be assembled and used on safely, in

accordance with the amusement device log and manual.

The ground shall be checked at regular intervals after assembly, to confirm that there is no

deterioration in its load bearing capacity, especially during adverse weather conditions. Drainage shall

be conside
