desk receiving the job request. OPNAV 5216/10 should be  unclassified  and  contain  only  the  information required to identify the material being received No classified information should be included on a receipt. The postcard receipt (back of OPNAV 5216/10 package) is given to the person delivering the job request. The postcard receipt is then presented to the front desk person when the completed job request is picked up. OPNAV 5216/10 receipts are retained for a minimum period of 2 years. Whenever you have questions about classified information  or  security  matters,  refer  to  the  Department of the Navy Information Security Program Regulation, OPNAVINST 5510.1, or the security manager of your command. VISITOR CONTROL Physical security is part of an overall Navy program that deals with physical measures designed to prevent unauthorized  access  to  equipment,  facilities,  and materials. Navy imaging facilities are a part of this physical security  program.  Physical  security  of  imaging  facilities is a direct, immediate, legal, and moral responsibility of every Photographer's Mate assigned to the activity. As  stated  earlier,  Navy  imaging  facilities  are considered limited access areas. The reception or job order desk area is the only place within the facility that unescorted personnel, other than personnel assigned to the activity, or visitors are permitted. Beyond the reception area, there must be a definite, well-defined limiting barrier. This barrier may be in the form of a warning sign, locked gate, or a door, depending on the degree  of  security  required. Procedures for the control of people entering the restricted areas of an imaging facility beyond the barrier include, as a minimum, an escort system. Escorting is a method for controlling personnel within the lab who are not  normally  authorized  access.  Whether  or  not  the escort remains with the visitor during the entire time of the visit is determined by the amount of security required, by the purpose of the visit, and by local written policy. Utility and maintenance personnel performing work at regular or irregular intervals and for short working  periods  should  be  handled  by  the  same procedures as those used for the control of visitors. People are curious and like to look at pictures. When unescorted  they  will  probably  look  through  the  pictures and negatives in the finishing area Even if they do not 14-7 take the pictures, they most probably will not place them in the same order and the finishing crew will have to re-sort  the  jobs. Even when your imaging facility does not handle classified work, you must become aware of the need for security.  You  must  be  accustomed  to  escorting  visitors. By  escorting  visitors,  you  will  find  that  the  dis- appearance or misplacement of equipment and materials is  minimized JOB CONTROL The  Navy  Visual  Information  Management  and Operations  Manual,  OPNAVINST  5290.1  (series), governs the administration and operation of Navy imaging facilities. It outlines the organization and administration  of  audiovisual  units  and  provides policies and instructions for the use of imaging products in the Navy. You should consult this manual for the most current  information  concerning  the  organization  of naval  imaging. The ability to track photographic jobs within your facility quickly and accurately depends on the job control system of your imaging facility. When the system is not used correctly, photographic requests, negatives, prints, and other requirements may be lost or misplaced.  This  causes  an  inordinate  delay  in  customer service that has a negative impact on your relationship with  other  divisions. JOB-ORDER LOG An unclassified job-order log is maintained by all imaging facilities. The log must contain, as a minimum, the  following  information:  sequential  job  order numbers,  security  classification,  product  identification, and disposition of the work request (person who picked up the job). Additional data required by your imaging facility, such as date and requester, may also be included in the job-order log. Unclassified  identifiers  are  used  to  refer  to classified  subjects.  A  separate  job-order  log  is maintained for classified work requests. Job order logs are created on the first day of each fiscal year, and the job order number is reset to 000001. The fiscal year of the federal government runs from 1 October to 30 September.
