When any work is to be done on a boiler component by way of repair, reassembly or replacement which if improperly performed may create a defect, the owner shall promptly notify the commissioner, or he shall notify the insurance company or the city official concerned. The inspecting authority may inspect the work in its discretion. Nothing in this Part (rule) is intended to impose or dispense with any lawful charge for such inspection.
