Signs are non-employee visual cues used to convey information or warnings, requiring no formal credentials. Security guards are trained personnel responsible for safety and protection, often needing certifications. While signs provide passive communication, security guards actively monitor and respond to incidents. Both play vital roles in safety but differ significantly in credentials, responsibilities, and work environment.
