Every police department should design and have a written policy on the collection, preservation, storage, and disposal of evidence. A written policy guarantees confidence that a specific standard is being used to protect all evidence in every case. Creation of a property control manual provides step-by-step procedures for the packaging, storage, and disposal of the evidence seized. Creation of a field evidence collection manual designates the specific procedures and requirements necessary to meet court standards when obtaining the evidence. Reviewing security and facilities is also vital to the storage of evidence. Strong policies that control keys, entry codes, and access increase efficiency while reducing distractions that limit the potential for lost or stolen property. Accurately completed forms and documentation lead the way for a solid chain of custody. Changes in Federal regulations that require blood-borne pathogens training mandate thorough training and necessary equipment for property personnel. Having working refrigerators and freezers for the preservation of DNA not only protects the evidence but reduces the risk of contamination. Yearly training reviews reduce worker risks. Properly posted signs increase awareness and meet legal requirements. Hepatitis vaccinations reduce the risk of disease and cross-contamination. Yearly audits of the property room is a minimum standard for every agency. Tracing items from entry to disposal, through filed paperwork or destruction bins, validates the integrity of the agency.
