Sec. 13007-1. An inspector of factories, attendance officer, or other officer charged with the enforcement of the laws relating to the employment of minors or school attendance may make demand on any employer in or about whose place or establishment or material or equipment a person apparently under the age of eighteen years is employed or permitted or suffered to work, and whose employment certificate is not filed as required by this act, that such employer shall furnish him satisfactory evidence that such person is in fact over eighteen years of age. The inspector of factories, attendance officer, or other officer charged with the enforcement of such laws, shall require from such employer unless an overage certificate is held by the employe the same evidence of age of such child as is required upon the issuance of an age and schooling certificate. Failure of such employer to produce such evidence shall be deemed a violation of the laws relating to the employment of minors. =Failure to produce satisfactory evidence of age.= Sec. 13007-2. In case any employer shall fail to produce and deliver to a factory inspector, truant officer, or other officer charged with the enforcement of this act, within ten days after demand made pursuant to section 13007-1 of this act, the evidence of age therein required, proof of the making of such demand and of such failure to produce and file such evidence shall be prima facie evidence of the illegal employment of such child in any prosecution brought therefor. =Age and schooling certificate; by whom approved.= Sec. 7766. An age and schooling certificate may be issued only by the superintendent of schools and only upon satisfactory proof that the child to whom the certificate is issued is over sixteen years of age and has satisfactorily passed a test for the completion of the work of the seventh grade, provided that residents of other states who work in Ohio must qualify as aforesaid with the proper school authority in the school district in which the establishment is located, as a condition of employment or service. Any such age and schooling certificate may be issued only upon satisfactory proof that the employment contemplated by the child is not prohibited by any law regulating the employment of such children; and when the employer of any minor for whom such age and schooling certificate shall have been issued shall keep such age and schooling certificate on file as provided by law, the provisions of section 6245-2, General Code, shall not apply to such employer in respect to such child while engaged in an employment legal for a child of the given sex and of the age stated therein.
