What type of facility is required for very-high-risk and high-risk items unless it is continuously manned?

The correct answer is an alarmed facility because very-high-risk and high-risk items require a heightened level of security to protect against theft, tampering, or unauthorized access. An alarmed facility is equipped with security systems, such as alarm systems, surveillance cameras, and intrusion detection mechanisms. These features provide a robust line of defense that does not rely solely on personnel presence for security.

This is especially important in environments where the risk of loss or compromise is critical. Having an alarmed facility ensures that even if the area is not continuously manned, any unauthorized access can trigger an alarm response, alerting security personnel or law enforcement to potential breaches. This proactive approach mitigates risks associated with the storage of sensitive or valuable materials.

Other types of facilities may provide some measure of safety, but they lack the comprehensive security features that an alarmed facility offers, particularly in instances where 24/7 monitoring cannot be guaranteed. Therefore, an alarmed facility is essential for securing very-high-risk and high-risk items effectively.
