66. On the occasion of any inspection under this Part the Director General shall where practicable notify the owner or occupier of the place of employment, and the employer of any employees employed thereat, of his presence unless he has reasonable grounds for believing that such notification might be prejudicial to the performance of his duties.

(d) a statement made by a person under this section shall, whenever possible, be reduced into writing and signed by the person making it or affixed with his thumb print, as the case may be, after it has been read to him in the language in which he made it and after he has been given an opportunity to make any correction he may wish; and
(e) any statement made and recorded under this section shall be admissible as evidence in any proceedings in Court.
