252.This section outlines the powers of the inspectors when inspecting premises. When an inspector enters premises which are liable to inspection he may:
make such examination and inquiry as may be necessary;
take possession of any document appearing to be relevant to the matter to which the inspection relates, or take any steps which appear necessary for preserving the document or preventing interference with it;
take copies of any such document;
require any person on the premises to produce, or secure the production of, any relevant document for inspection; and
examine, or require to be examined, either alone or in the presence of another person, any person on the premises whom he has reasonable cause to believe to be able to give information relevant to that matter.
