What should a security guard do if they encounter a suspicious bag left unattended?

When a security guard encounters a suspicious bag left unattended, the appropriate action is to secure the area and notify law enforcement immediately. This course of action prioritizes safety and security. An unattended bag could pose a danger, potentially containing hazardous materials, explosives, or other harmful items. By securing the area, the guard prevents others from approaching the bag, reducing the risk of injury or panic. Notifying law enforcement ensures that trained professionals can handle the situation safely and effectively. This approach follows established protocols for dealing with suspicious items and aligns with best practices in security, emphasizing caution and appropriate escalation to authorities.
