Duties 3 1 Every employer shall— a ensure compliance with the provisions of these Regulations in respect of any work carried out by his employees; and b ensure compliance, so far as is reasonably practicable, with the provisions of these Regulations in respect of any work carried out by persons other than his employees insofar as the provisions relate to matters which are within his control. 2 Every self-employed person shall— a comply with the provisions of these Regulations in respect of his own work; and b ensure compliance, so far as is reasonably practicable, with the provisions of these Regulations in respect of any work carried out by other persons insofar as the provisions relate to matters which are within his control. Work in confined spaces 4 1 A person at work shall not enter a confined space to carry out work for any purpose unless it is not reasonably practicable to achieve that purpose without such entry. 2 Without prejudice to paragraph (1), so far as is reasonably practicable, a person at work shall not enter or carry out any work in, or (other than as a result of an emergency) leave, a confined space otherwise than in accordance with a system of work which, in relation to any relevant specified risks, renders that work safe and without risks to health. Emergency arrangements 5 1 Without prejudice to regulation 4, a person at work shall not enter or carry out work in a confined space unless there have been prepared in respect of that confined space suitable and sufficient arrangements for the rescue of persons in the event of an emergency, whether or not arising out of a specified risk. 2 Without prejudice to the generality of paragraph (1), the arrangements referred to in that paragraph shall not be suitable and sufficient unless— a they reduce, so far as is reasonably practicable, the risks to the health and safety of any person required to put the arrangements for rescue into operation; and b they require, where the need for resuscitation of any person is a likely consequence of a relevant specified risk, the provision and maintenance of such equipment as is necessary to enable resuscitation procedures to be carried out. 3 Whenever there arises any circumstance to which the arrangements referred to in paragraph (1) relate, those arrangements, or the relevant part of those arrangements, shall immediately be put into operation. Exemption certificates 6 1 Subject to paragraph (2), the Department may, by a certificate in writing, exempt— a any person or class of persons; or b any type or class of confined space, from the application of any of the requirements or prohibitions imposed by these Regulations, and any such exemption may be granted subject to conditions and to a limit of time and may be revoked at any time by the Department by a further certificate in writing. 2 The Department shall not grant any such exemption 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; and b any other requirements imposed by or under any statutory provisions which apply to the case, it is satisfied that the health and safety of persons who are likely to be affected by the exemption will not be prejudiced in consequence of it. Defence in proceedings 7 1 In any proceedings for an offence for a contravention of regulation 5(3) it shall be a defence for the person charged to prove— a that the contravention was due to the act or default of another person not being one of his employees (hereinafter called “the other person”); and b that he took all reasonable precautions and exercised all due diligence to avoid the contravention. 2 The person charged shall not, without leave of the court, be entitled to rely on the defence referred to in paragraph (1) unless, within a period ending seven clear days before the hearing, he has served on the prosecutor a notice in writing giving such information identifying or assisting in the identification of the other person as was then in his possession. 3 Where a contravention of the provision referred to in paragraph (1) by any person is due to the act or default of some other person, that other person shall be guilty of the offence which would, but for any defence under this regulation available to the first-mentioned person, be constituted by the act or default.
