48.—(1) The governor may order an inmate who is refractory or violent to be confined temporarily in a special cell or room, but an inmate shall not be so confined as a punishment, or after he has ceased to be refractory or violent.
(2) A cell or room shall not be used for the purpose of this rule unless it has been certified by an officer of the Secretary of State (not being an officer of a young offender institution) that it is suitable for the purpose, that its size, lighting, heating, ventilation and fittings are adequate for health, and that it allows the inmate to communicate at any time with an officer.
(3) In relation to any young offender institution, section 14(6) of the Prison Act 1952 shall have effect so as to enable the provision of special rooms instead of special cells for the temporary confinement of refractory or violent inmates.
