If the office of the attorney general is of opinion, after such investigation, that the factory or workshop is not properly lighted, it shall notify the owner or person in charge, and shall specify what changes should be made in order to light it properly, and the owner or lessee thereof shall make the changes so specified as soon as it can be done with reasonable diligence. If such owner or lessee fails to comply with any such order he shall be punished by a fine of not more than five hundred dollars, provided such failure is not the result of causes beyond his control.
