Where handcuffs, or waist restraints used in conjunction with handcuffs, are applied on a prisoner who is being escorted to or from medical treatment, or receiving medical treatment, escorting officers must, taking into account the advice of the treating medical practitioner,—
(a)
implement any measures that are reasonably necessary to ensure that the mechanical restraint does not adversely affect the health and comfort of the prisoner; and
(b)
remove the mechanical restraint if necessary to allow the prisoner to receive medical treatment.
