What do first responders typically include?

First responders typically include firefighters and medical personnel because these groups are specifically trained to provide immediate assistance in emergency situations. Firefighters are equipped to handle fires, rescue victims, and contain hazardous materials, while medical personnel, such as paramedics and emergency medical technicians, are trained to assess and provide life-saving care to individuals in medical emergencies.

While other options mention roles related to emergency responses, they do not encompass the core definition of first responders, which primarily refers to professionals dedicated to managing emergencies right from the start. Citizens trained in emergency response may assist but are not usually included in the primary definition of first responders. The presence of all individuals at the scene can include bystanders who may not have formal training or roles in emergency management. Therefore, the inclusion of both firefighters and medical personnel accurately captures the essence of what constitutes first responders.
