First responders are individuals who are among the first to arrive and provide assistance at the scene of emergencies such as accidents, natural disasters, and other crises. This includes professionals such as paramedics, firefighters, police officers, and emergency medical technicians (EMTs). The main goal of first responders is to assess and address the immediate needs of individuals in distress and to help mitigate further harm or damage. Research in this area often focuses on improving response protocols, training techniques, equipment, and overall effectiveness in emergency situations. Additionally, studies may also explore the psychological impact of being a first responder, as well as ways to support their mental health and well-being.
