(h)require any person to afford him such facilities and assistance with respect to any matters or things within that person's control or in relation to which that person has responsibilities as are necessary to enable the inspector to exercise any of the powers conferred on him by this paragraph.
(2) An inspector shall not exercise the power conferred by paragraph (1)(d)(i) above so as to require the shutting down of a pipe-line, or the discontinuance of the conveyance of anything through it, except in a case where the inspector is of the opinion that there is a risk of an accident causing the death or loss of, or serious bodily injury to, any person, or such an accident has occurred, or where the inspector is of the opinion that the escape of anything from the pipe-line has occurred or is imminent.
(3) Where an inspector proposes to exercise either of the powers conferred by paragraph (1)(c) and (d)(iii) above on any premises, vessel or installation, he shall, if so requested by a person who at the time is present in and has responsibilities in relation to those premises or that vessel or installation, as the case may be, do, or cause to be done anything which is to be done by virtue of the power in the presence of that person.
(4) A requirement under paragraph (1)(d)(i) above shall cease to have effect on the expiration of a period of 3 days beginning with the date on which it was made unless the Secretary of State by notice given to the person on whom it was imposed extends its operation either in its original or a modified form for additional periods.
(5) Before exercising any of the powers conferred by paragraph (1)(c) and (d)(i) and (ii) above, an inspector shall, except in a case of urgency, consult such persons as appear to him appropriate for the purposes of ascertaining what may be the consequence of doing anything he proposes to do under the power.
