Which of the following is not part of a security guard's role?

A security guard's role is primarily focused on maintaining a safe and secure environment. This includes activities such as monitoring theft prevention efforts, documenting incidents accurately, and ensuring crowd safety during events. Each of these responsibilities is integral to the security profession.

Complex medical procedures, however, fall outside the typical scope of a security guard's duties. While a security guard may need to respond to medical emergencies and provide basic first aid, they are not trained to perform advanced medical interventions. Their training is focused on prevention, observation, and emergency response within the framework of security, making the performance of complex medical procedures an inappropriate expectation for someone in this role.
