Whether centralized or decentralized within the laboratory, all evidence storage facilities must maintain the physical integrity of the evidence, to include provision for the following:

  • Basic environmental controls for temperature and humidity
  • Alarm systems for unauthorized entry (motion, vibration, and sound detection)
  • Video coverage of sensitive areas
  • Fire alarm and sprinkler systems
  • Refrigeration for certain types of evidence
  • Protection from floods
  • Protection from pests
  • Storage located under a secure roof, particularly in storm-threatened areas
  • Fume hood, as appropriate to preserve evidence
