What is the Owner Controlled Area (OCA)?

• A. Company property surrounding the protected area's security fence, access limited to official business.
• B. A public parking area near the facility
• C. The entire plant including the reactor hall
• D. A courtyard used for training

Answer: (A)

The Owner Controlled Area is the company property surrounding the security fence of the protected area, where access is restricted to official business. This creates a controlled buffer zone that security personnel monitor to ensure that only authorized personnel can approach or enter the protected area, often with credential checks and escorts as needed. It’s not a public parking area, not the entire plant (which has its own broader boundaries), and not a training courtyard. The OCA focuses specifically on the area around the protected zone under the company’s control to maintain security before someone reaches the sensitive space.
