The job description of a security officer can vary widely depending on the needs of the location that they are protecting. At every location with guard services, security and local management create a list of post orders, tailor made for each site, that details every action that the officer is to perform.
Post orders need to be well detailed, and also easy to understand with no room for interpretation. Each order should only cover a single subject, and for a particularly complex site or for officers expected to be able to cover multiple sites a thorough and cross-referenced index can be created in case a specific order needs to be reviewed quickly. In addition to all daily duties, such as specifics on rounds or door locking procedures, all information that is relevant or may be needed by the officer should be included; such as emergency procedures and contact information, or evacuation plans.
Post orders should be available for consultation at any time. If the location has a guard shack or similar main office that the officer is posted, that is the most logical choice. If a patrol vehicle is operated on site, that is another ideal place to store post orders. If there is no viable option to store orders on-site, one solution is to issue photo-reduced copies to each officer to carry in their uniform.
