considered if overall security is to be reached. Consideration must be given to the vulnerability.
Contents are sometimes left unattended for long periods. The location where the cabinet is to be
placed is also important. The building and room in which the cabinet is to be placed must be carefully
evaluated. Keep in mind the accessibility and ease of removal of the cabinet. Selection of a position
for the cabinet should result in its being least vulnerable to unauthorized movement by heavy lifting
equipment. The position should make it very hard for unauthorized persons to remove the cabinet.
