Securing evidence at a crime scene hinges on preventing contamination and preserving the material’s integrity through controlled handling and meticulous recordkeeping. Limiting access ensures only trained personnel touch the items, reducing the chance of introducing foreign material. Wearing gloves and changing them between handling different items prevents cross-contamination from one piece of evidence to another. Documenting every handling action as it happens creates a continuous, verifiable record—establishing the chain of custody that shows who touched what, when, and how it was stored or moved. Proper packaging, labeling, and secure storage further protect the evidence from loss or tampering and support its admissibility in court. Handling with bare hands risks contaminating evidence and transferring materials; documenting after the fact or storing evidence in an unsecured area compromises integrity and security.
