The chief inspector, or his or her authorized representative, may at any time suspend an inspection certificate when, in his or her opinion, the boiler or unfired pressure vessel for which it was issued cannot be operated without menace to the public safety, or when the boiler or unfired pressure vessel is found not to comply with the rules herein provided. A special inspector shall have corresponding powers with respect to inspection certificates for boilers or unfired pressure vessels insured or operated by the company employing him or her. Such suspension of an inspection certificate shall continue in effect until such boiler or unfired pressure vessel shall have been made to conform to the rules of the board, and until said inspection certificate shall have been reinstated.
