Which of the following is NOT a purpose of a vault or strong room in evidence handling?

A vault or strong room in evidence handling is designed primarily for security and protection. The purpose of such facilities is to safeguard sensitive evidence from unauthorized access, tampering, or environmental damage. By definition, these spaces are intended to limit access to authorized personnel only, ensuring that the integrity of the evidence is maintained.

The purposes of protecting sensitive evidence, controlling the storage environment, and maintaining a secure chain of custody are all critical aspects of evidence handling. Security measures are in place to prevent any alteration or contamination of the evidence, while environmental controls like temperature and humidity help preserve physical items. Maintaining a secure chain of custody is crucial for legal proceedings, as it ensures that evidence can be traced and verified from the time it is collected to when it is presented in court.

In contrast, allowing easy access to all personnel undermines the very purpose of a vault or strong room, as unrestricted access could lead to breaches in security and compromise the evidence. Therefore, this option is correctly identified as not being a purpose of a vault or strong room in evidence handling.
