49.—(1) The governor may order an inmate, other than an inmate aged less than 17, to be put under restraint where this is necessary to prevent the inmate from injuring himself or others, damaging property or creating a disturbance.
(2) Notice of such an order shall be given without delay to a member of the board of visitors and to the medical officer.
(3) On receipt of the notice the medical officer shall inform the governor whether he concurs in the order. The governor shall give effect to any recommendation which the medical officer may make.
(4) An inmate 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 a member of the board of visitors or by an officer of the Secretary of State (not being an officer of a young offender institution). Such a direction shall state the grounds for the restraint and the time during which it may continue.
(5) Particulars of every case of restraint under the foregoing provisions of this rule shall be forthwith recorded.
(6) Except as provided by this rule no inmate shall be put under restraint otherwise than for safe custody during removal, or on medical grounds by direction of the medical officer. No inmate shall be put under restraint as a punishment.
(7) 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.
