Which of the following is NOT prohibited in the Protected Area?

Work-related tools are essential for conducting tasks and ensuring operations within a nuclear facility are performed safely and efficiently. These tools are often vetted and allowed in the Protected Area because they are integral to the work process and contribute to maintaining safety protocols.

In contrast, alcoholic drinks, unauthorized weapons, and repellant sprays are considered security risks or hazards and are prohibited within the Protected Area. Alcohol can impair judgment and keenness which is critical in a nuclear environment. Unauthorized weapons pose a direct threat to safety and security protocols, while repellant sprays, depending on their chemical composition, might introduce safety hazards or interfere with sensitive equipment. Thus, work-related tools are the only items among the options provided that are permissible, as they support the operational needs of the facility while adhering to safety regulations.
