How must a veterinarian maintain access to controlled substances storage areas?

A veterinarian must maintain a written list of individuals with access to controlled substances storage areas to ensure compliance with regulations and standards that govern the handling of these substances. This written documentation serves several important purposes:

1. Accountability: By maintaining a formal record, the veterinarian can track who has access to controlled substances at all times. This reduces the risk of misuse or theft and ensures that all individuals responsible for handling these substances are properly trained and knowledgeable about regulatory requirements.

2. Regulatory Compliance: Various state and federal regulations stipulate that veterinary practices must keep thorough records regarding the management of controlled substances. A written list aligns with these legal requirements and helps in audits or inspections by regulatory bodies.

3. Clarity and Precision: A written list eliminates ambiguity that may arise from verbal agreements. It provides a clear and unambiguous record that can be easily referenced, which is crucial in professional settings where controlled substances are involved.

4. Emergency Preparedness: In case of an incident or emergency, having a formalized list of individuals with access allows for quick action and response, ensuring that the right protocols are followed, and that only authorized personnel are involved in handling controlled substances.
