(e)executing any operations authorised by paragraph (b) of subsection (1) of section thirteen of this Act;
and may execute any of the said purposes.
(2)The foregoing subsection shall, subject as aforesaid, apply, as it applies to persons authorised as mentioned in that subsection for the purposes so mentioned, to any person authorised in writing by a local authority for the purpose of—
(a)inspecting any building which the local authority consider should be examined in order to determine whether to exercise their powers under section eleven of this Act; or

(3)No person shall be entitled to enter any premises by virtue of subsection (1) of this section for the purposes specified in paragraph (c) thereof, or by virtue of subsection (2) of this section, unless he has given three days' notice of his intention to do so to the occupier, and (unless the owner is unknown) also to the owner, of the premises.
(4)If a justice of the peace (not being a justice of the peace who is a member of the buildings authority or the local authority) on sworn information in writing—

(b)is also satisfied either—
(i)that admission to the premises has been refused, or a refusal is apprehended and that notice of the intention to apply for a warrant has been given to the occupier, of

the justice of the peace may, notwithstanding anything in subsection (3) of this section, by warrant under his hand authorise the buildings authority or local authority, as the case may be, by any authorised officer, to enter the premises, if need be by force.
(5)A person entering any premises by virtue of this section, or of a warrant issued thereunder, may take with him such other persons as may be necessary, and on leaving any unoccupied premises which he has entered by virtue of such a warrant shall leave them as effectively secured against unauthorised entry as he found them.

(8)If any person who, by virtue of the provisions of this section, or of a warrant issued thereunder, enters a factory or work-place, discloses to any other person any information obtained by him in the factory or workplace with regard to any manufacturing process or trade secret, he shall, unless such disclosure was made in the performance of his duty, be guilty of an offence against this Act.
(9)In this section any reference to premises includes a reference to sites and buildings, and any reference to a justice of the peace includes a reference to the sheriff.
(10)The master of works or any person authorised by him may require—
(a)any person who has made an application for a direction under section four of this Act, or for a warrant, in respect of a building, or
(b)any person by whom, or on whose behalf, a building is being or has been constructed in pursuance of a warrant,
to cause to be carried out such reasonable test of materials forming part of the building, or used or proposed to be used in the construction of the building, as may be specified in the requirement; and the expense of carrying out any test to be carried out under this subsection shall be met by the person so required:
Provided that the buildings authority, on application made to them, may if they think fit direct that the expense of carrying out any such test as aforesaid, or such part of that expense as may be specified in their direction, shall be met by the local authority.
