## 1 Introduction
### First Responders and Operation Type Description  
The different types of missions have been grouped into five main categories: Firefighting, Search and Rescue, Natural Disasters, Emergency Medical Services, and Hazardous Materials (Hazmat) Incidents.  
* Firefighter: The main task of a firefighter is to control and extinguish fires occurring in settings such as residential, commercial, and wild-land areas. Frequent circumstances in these operations include combustible materials, with major risks including smoke, oxygen deficiency, elevated temperatures, poisonous atmospheres, and violent air flows, creating toxic and dangerous environments [27].
* Search and Rescue: They coordinate efforts to locate and assist persons, vehicles, other conveyances, or buildings considered in imminent danger. Participation in these tasks requires prior training and knowledge of the use of appropriate resources to locate persons in distress and provide them with the necessary assistance, including initial medical care, to ensure their safety and well-being.
* Natural Disasters: The main task of these FRs is to provide assistance in natural disaster situations such as forest fires, floods, extreme snowstorms, landslides, earthquakes or hurricanes. This assistance takes the form of evacuation tasks, search and rescue operations, and health care, among others.
* Emergency Medical Services (EMS): They provide urgent pre-hospital treatment and stabilization for serious illnesses and injuries that occur in accidental circumstances. In some situations, the transport of injured victims is the next point of care, typically to an emergency department of a hospital.
* Hazardous Materials (Hazmat) Incidents: Mishaps occurring as a result of the release or spillage of hazardous materials involve a high risk to public health and the environment, given the toxicity or radioactivity of the scenario produced by the chemicals, gases or radioactive substances released. The FRs trained to assist in these rescue tasks have the objective of controlling and decontaminating the hazardous materials as well as managing the relevant health care.  
In order to design a system that caters to the diverse requirements of various rescue situations, three distinct operational scenarios have been distinguished:  
* Survival: In this scenario, the survival of the First Responder (FR) is prioritized, so the amount of information exposed at the interface is minimum quantity to avoid overwhelming the FR with unnecessary information details and focus on what is essential for survival. The main purpose of this information is to facilitate the FR's immediate exit from the scenario.
* Search: This scenario is characterized by the fact that the additional information facilitates the search for victims within a rescue scenario. As this is an a priori activity, the amount of information provided is of a medium level.
* Complete: This scenario differs from the previous scenarios in that it is a non-threatening situation, where the FR is fully capable of receiving complete mission status information. That is, it is considered the maximum amount of information that an FR can receive in a rescue scenario.  
The primary objective is to determine unique combinations of awareness modules tailored to each scenario, optimizing the FR's response capabilities and ensuring the effective handling of various rescue situations.
