When it is proposed to impose a punishment of confinement in a cell or room, the medical officer, or a medical practitioner such as is mentioned in rule 27(3), shall inform the governor whether there are any medical reasons why the inmate should not be so dealt with. The governor shall give effect to any recommendation which may be made under this paragraph.

No cell or room shall be used as a detention cell or room for the purpose of a punishment of confinement to a cell or room 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.
