Okla. Stat. tit. 57 § 212
When there is a need therefor at any state eleemosynary institution, maintenance services of prisoners may be requisitioned by the governing body of such institution. Such requisition shall be submitted to the Director of Corrections or the designee of the Director and shall state the services desired and the number of prisoners necessary therefor, and there shall be incorporated therein or attached thereto a detailed statement showing arrangements for quarters, subsistence, and security of the prisoners. If the Director of Corrections or the designee of the Director, after considering such requisition, finds that there is a need for the services desired or any part thereof, the Director or designee may thereupon direct the appropriate warden or superintendent to furnish qualified prisoner personnel to perform the services found to be needed at the institution for which the requisition was made.
