Which type of access allows no entry to unauthorized personnel in a breeding facility?

Barrier access is specifically designed to prevent unauthorized personnel from entering sensitive areas of a breeding facility. This type of access typically involves physical barriers such as locked doors, entry controls, and security measures that require authorized personnel to use identification badges or codes to gain entry. The objective of barrier access is to maintain biosecurity and protect the animals from potential contamination, stress, or other risks associated with unauthorized individuals.

In contrast, options representing full access, limited access, and open access tend to allow varying degrees of entry that can compromise the security and integrity of the facility. These types of access may not have sufficient controls to prevent unauthorized individuals from interfering with breeding operations or contacting the animals, making them less suitable for environments where stringent security and animal welfare protocols must be upheld. Barrier access effectively addresses these concerns by instituting clear, physical limitations that enforce security regulations.
