14 Power to grant exemptions
1 Subject to paragraph (3), the Executive may, by a certificate in writing, exempt any person or class of persons from all or any of the requirements or prohibitions imposed by or under these Regulations, save where such an exemption would contravene rules imposed by other enactments.
2 An exemption granted under paragraph (1) may be—
(a) subject to conditions,
(b) subject to a time limit, and
(c) revoked at any time by a certificate in writing.
3 The Executive must not grant an exemption under paragraph (1) unless, having regard to the circumstances of the case, and in particular to—
(a) the conditions, if any, which it proposes to attach to the exemption under paragraph (2); and
(b) any requirements imposed by or under any enactments which apply to the case,
it is satisfied that the safety of persons who are likely to be affected by the exemption will not be prejudiced in consequence of it.
