The government agency should implement several physical controls to safeguard classified documents from being taken out of the office premises without proper authorization. Here are the steps they should take:

1. Security Guards: They should hire security guards to monitor the premises and ensure that no unauthorized individuals are allowed access to the office. The guards can also check bags and other belongings of employees as they leave to ensure no documents are being taken out.

2. CCTV Surveillance: Installing CCTV cameras around the office can help monitor activities and identify any suspicious behavior. The footage can also serve as evidence in case of any security breaches.

3. Document Shredders: Having document shredders in the office can ensure that any classified documents that are no longer needed are properly destroyed and cannot be taken out of the office.

4. Mantrap: A mantrap is a security device that monitors and controls two interlocking doors. No door can be opened until the other is closed and it can trap potential intruders. This can be installed at the entrance and exit points of the office to ensure that no unauthorized individuals can enter or leave with classified documents.

5. Firewall: While this is not a physical control, it is a crucial part of information security. A firewall can prevent unauthorized access to the agency's network and protect the classified documents stored digitally.

By implementing these controls, the agency can significantly reduce the risk of classified documents being taken out of the office without proper authorization.
