All persons connected with any such State institution, charitable institution, prison, almshouse, poorhouse, hospital, house, place, institution, association, society, or home, as officers, or charged with the management thereof by law or otherwise, or in any way having the care, custody, control, or management thereof, or connected therewith as employés, are hereby directed and required to give the commissioner, or such officer, inspector, or agent of the department, such means, facilities, and opportunity for such visitation, examination, inquiry, and interrogation as is hereby provided and required or as the department, by its duly ordained rules or regulations, may require.
Whenever, upon such visitation, examination, and inspection of any penitentiary, prison, reformatory, almshouse, or poorhouse, any condition is found to exist therein which, in the opinion of the commissioner, is unlawful or detrimental to the proper maintenance, discipline, hygienic conditions of such penitentiary, prison, reformatory, almshouse, or poorhouse, or to the proper care, maintenance, custody, and welfare of the inmates thereof or the persons committed thereto or being treated, detained, or residing therein, the commissioner shall direct the officer or officers charged by law with or in any way having or exercising the control, government, or management of such penitentiary, prison, reformatory, almshouse, or poorhouse, to correct the said objectionable condition in the manner and within the time specified by the commissioner. In case of the neglect, refusal, or failure of any such officer to comply with such directions, the commissioner shall certify the facts in the case to the district attorney of the proper county, whose duty it shall be thereupon to proceed by indictment or otherwise to remedy the said objectionable condition.
