No rate or rates fixed or determined by the Board shall take effect until it shall have entered an order or orders fixing and determining same, and shall give notice thereof to all fire insurance companies affected by this subchapter, authorized to transact business in the State. The Board, and any inspector or other agent or employee thereof, who shall inspect any risk for the purpose of enabling the Board to fix and determine the reasonable rate to be charged thereon, shall furnish to the owner of such risk at the date of such inspection a copy of the inspection report, showing all defects that may operate as charges to increase the insurance rate.
