First. That an employer will be fully protected against unintentional violations of sections 3, 4 and 5 of this act³ and regulations issued thereunder, if before employing or permitting any female under eighteen years of age to work in his establishment he has received from that employe an age certificate issued by the proper officials of the school district in which the prospective employe resides. These age certificates must be kept on file by the employer for inspection by authorized representatives of the Department of Labor and Industry so long as the female is employed or until she reaches the age of eighteen whichever occurs sooner. An age certificate will be no defense to any violation of the provisions of this law and regulations issued thereunder if the employer knows that it was obtained falsely or after knowledge of the true age of the employe becomes known to him.

Third. That under no circumstances shall any person be sentenced to imprisonment for more than one year for any one violation of this act.

Fourth. That whenever a violation of any of the provisions of this act shall also be a violation of the laws of this Commonwealth regulating the hours of labor and conditions of employment of minors, penalties shall be imposed under only one of such acts.
