What is a guard likely inspecting for when checking belongings of a person leaving a building?

The correct answer highlights the primary responsibility of security guards in many contexts, particularly when it comes to ensuring that company assets are protected. When checking the belongings of a person leaving a building, a guard is likely inspecting for company-owned property or items to prevent theft and safeguard the organization's assets.

This practice is essential for maintaining security protocols and ensuring that items owned by the business are not being taken without authorization. A guard's role in this process is typically part of their obligation to enforce company policies regarding inventory and asset management.

The other options, while important in certain contexts, may not be the primary objective of a guard in this scenario. For instance, personal items are usually not the focus since they typically do not belong to the company. Checking for illegal substances and weapons is vital in security checks, particularly in high-security environments, but may not be the immediate concern when someone is leaving a facility, where the focus is more on what belongs to the company.
