• Specimens are received at CAMI in the secured accessioning room with the Chain of Custody seal intact.
  • In the accessioning room the Chain of Custody seal is broken and the contents of the TOX-BOX are carefully inventoried to account for every sample of evidence received from an aviation accident.
  • Detailed reports are prepared to account for every drop of sample used from a case. All batches submitted for analysis contain a blind positive control and a blind negative control to monitor these results.
Three levels of security are maintained to ensure the integrity of the test results:

Controlled Area
All external doors of the Civil Aerospace Medical Institute (CAMI) are locked, and secured on weekends, holidays, and from 6:00 p.m. to 6:00 a.m. on weekdays. Entrance by anyone into CAMI on weekends, holidays, and nights is recorded by security in the headquarters building. The name, destination, and purpose of all such persons seeking entrance will be recorded by security. All persons actually entering the building in this fashion are monitored by TV cameras at the north entrance of CAMI. (this is the only allowed entrance during off hours).

Entrance into the building requires voice communication from the pre-registered entrant to Security. Upon proper final identification, via TV cameras mounted both inside and outside the north door, security will electronically activate a door release mechanism. Security periodically checks to assure that all perimeter doors are secure, and forced entry has not occurred. These inspections occur 24 hours a day, 7 days a week.

Secured Area
Only authorized personnel are provided access codes to the hallway doors leading into the east wing of the third floor of CAMI. Each person authorized to enter this section of CAMI is given a unique access code to enter specified areas. This code identifies the person entering the secured area, the door entered, the date of entry, and the time of entry in the security computer. All unauthorized persons desiring entrance to the secured area of Forensic Toxicology ring a buzzer outside the main east wing hallway door.

Persons seeking entrance identify themselves over a speaker phone, and are directed to move to the window area of the door. A closed circuit TV camera allows the departmental secretary to make a visual identification of the person. The door may then be electronically released from the secretary's office. The TV monitor allows all persons entering the hall to be continually monitored, as they approach the departmental office for sign-in. All visitors to the east wing of the third floor of CAMI must register in the Toxicology and Accident Research Laboratory Office.

Restricted Areas (Forensic Toxicology, Analytical, and Accessioning)
All analytical and accessioning doors are locked electronically and with a dead bolt lock during non working hours. The Analysts are not allowed in the accessioning area. motion sensor for the accessioning area is armed at nights, weekends, holidays, or any other times the area is not actively in use. Doors leading to the analytical areas remain closed, and secured whenever analyses of specimens are being performed. All aliquots of specimens, in the process of being analyzed, are monitored or secured at all times. Specimens in the process of analysis are stored inside the secured evidence room, located inside the accessioning area.

Completed cases are secured in the permanent evidence freezer. At no time are specimens taken outside of the secured accessioning areas, except for the purpose of transferring them to an authorized destination, such as permanent storage, or when the cases are ready to be destroyed. All records regarding cases are maintained inside the evidence storage area of accessioning. Individuals visiting the Forensic Toxicology accessioning area or analytical areas must be escorted at all times by a person with a Forensic Toxicology photo identification badge, marked with a red label.
