Conn. Agencies Regs. § 21a-408-38
During times when the dispensary leaves the dispensary department for a few moments, the dispensary shall take measures to ensure that adequate security of the dispensary department is provided and that entry by unauthorized persons is prevented or immediately detected. The presence of a dispensary technician in the dispensary department during these times shall be considered adequate security. If no such dispensary technician is available for this purpose, and the dispensary department is not within the view of the dispensary, the dispensary shall physically or electronically secure the dispensary department through the use of mechanisms such as a locked barrier or an alarm system that will prevent or immediately detect access to such department.
