What documentation accompanies disposal and confirmation activities in the seventh step?

• A. Chain of Custody paperwork per policy
• B. Initial and confirmation testing results in OIMS
• C. Professional conduct and confidentiality
• D. Temperature observation during swab/UA testing

Answer: (A)

The action at disposal and confirmation requires an auditable record that shows every step of how the material was handled, transferred, and finally disposed of. This is captured by Chain of Custody paperwork per policy. It creates a clear, time-stamped trail of who had custody, when transfers occurred, where disposal took place, and who authorized each step. That trail is essential for accountability and for defending the process in audits or inquiries, ensuring the integrity of the disposal and confirmation activities. Other elements listed—testing results, confidentiality in general, or temperature checks during testing—pertain to the testing phase or general ethics, not to the documentation that proves proper disposal and verification.
