Instruments of restraint and force can only be used in exceptional cases, where all other control methods have been exhausted and failed, and only as explicitly authorized and specified by law and regulation. They should not cause humiliation or degradation, and should be used restrictively and only for the shortest possible period of time. By order of the director of the administration, such instruments might be resorted to in order to prevent the juvenile from inflicting self-injury, injuries to others or serious destruction of property. In such instances, the director should at once consult medical and other relevant personnel and report to the higher administrative authority. 65. The carrying and use of weapons by personnel should be prohibited in any facility where juveniles are detained. L. Disciplinary procedures 66.

All disciplinary measures constituting cruel, inhuman or degrading treatment shall be strictly prohibited, including corporal punishment, placement in a dark cell, closed or solitary confinement or any other punishment that may compromise the physical or mental health of the juvenile concerned.

No juvenile should be disciplinarily sanctioned except in strict accordance with the terms of the law and regulations in force. No juvenile should be sanctioned unless he or she has been informed of the alleged infraction in a manner appropriate to the full understanding of the juvenile, and given a proper opportunity of presenting his or her defence, including the right of appeal to a competent impartial authority. Complete records should be kept of all disciplinary proceedings. 71.
