The governor may order a prisoner to be put under restraint where this is necessary to prevent the prisoner from injuring himself or others, damaging property or creating a disturbance.

Notice of such an order shall be given without delay to a member of the F4independent monitoring board, and F1to a registered medical practitioner or to a registered nurseF5working within the prison.

On receipt of the notice, F2the registered medical practitioner or registered nurse referred to in paragraph (2), shall inform the governor whether there are any medical reasons why the prisoner should not be put under restraint. The governor shall give effect to any recommendation which may be made under this paragraph.

A prisoner shall not be kept under restraint longer than necessary, nor shall he be so kept for longer than 24 hours without a direction in writing given by F7... an officer of the Secretary of State (not being an officer of a prison). Such a direction shall state the grounds for the restraint and the time during which it may continue.

Particulars of every case of restraint under the foregoing provisions of this rule shall be forthwith recorded.

Except as provided by this rule no prisoner shall be put under restraint otherwise than for safe custody during removal, or on medical grounds by direction F3of a registered medical practitioner or of a registered nurseF6working within the prison. No prisoner shall be put under restraint as a punishment.

Any means of restraint shall be of a pattern authorised by the Secretary of State, and shall be used in such manner and under such conditions as the Secretary of State may direct.
