Security guards follow a strict set of rules to ensure safety, professionalism, and legal compliance. Their primary responsibility is to protect people, property, and assets by maintaining a visible presence and monitoring for suspicious activity. They must always remain alert, act quickly in emergencies, and report incidents accurately. Security guards are expected to follow the law, respect privacy, and avoid using excessive force. They must also adhere to company policies, wear proper uniforms, and communicate effectively with clients, law enforcement, and the public. Integrity, reliability, and strong observational skills are essential for performing their duties responsibly and effectively.
