Which of the following practices may potentially compromise security of an animal facility?

• A. Visitors may enter the facility freely during regular work hours.
• B. Doors are secured at all times.
• C. Facility staff is trained to avoid confrontation with animal rights activists.
• D. Security cameras are installed to support surveillance.

Answer: (A)

Allowing visitors to enter freely during regular work hours undermines access control and makes it easy for an unauthorized person to access sensitive spaces such as animal housing, supply areas, or labs. In an animal facility, security isn’t just about keeping out criminals; it’s about preventing accidental or deliberate exposure to animals, pathogens, or regulated materials. Controlled entry with sign-in, badge checks, verification, and escorting helps ensure that everyone in the facility is known, trained, and aware of safety and biosecurity rules. Free entry also increases the risk of tailgating—someone following a staff member to slip in without a badge—and makes it harder to track who was in which areas if an incident occurs. By contrast, doors secured at all times, staff training on handling confrontations, and surveillance cameras all strengthen security through fewer opportunities for unauthorized access, better deterrence, and clearer incident evidence. Unrestricted visitor access during operation hours is the scenario that most clearly compromises security.
