(a)paragraphs (3) to (7) shall not apply to the works or, as the case may be, to the specified part of the works; but

included in such order.

(13) Where the Department is of opinion that any work is of such character as is likely to cause the evolution of any noxious or offensive gas, the Department may, notwithstanding that the provisions of the Alkali Act may not apply to that work, authorise an inspector appointed under that Act to enter and inspect such work.
