7. Which of the above diagrams best represents this description: A. Assessing a fireground for victims -- their location, number and condition is not an easy task. There is an inclination on the part of arriving units to ask onlookers if everyone is out. Can you trust their answers? The dynamics of a fireground change quickly especially during the first few minutes and it is the responsibility of the Fire Ground Commander in charge of the scene to sort out the situation. A complete and thorough primary search is the only accurate way to determine and verify the status of victims. Firefighters on the scene must treat the supporting evidence of spectators with skepticism owing to the stress of situation and the possibility of troublemakers making false reports in order to gain attention or make the fireground more chaotic. Conscientious onlookers may be proven mistaken, or victims in an effort to escape the fire may have moved their location from where they were last seen, therefore, the location of a victim must be determined by primary search. Often the injuries suffered by a victim can be predicated on the intensity of the fire and amount of smoke; involvement timelines can be misleading as smoke inhalation by sleeping victims can occur in a very short amount of time. The longer the involvement, and generally the more smoke and flame, the more difficult the rescue and severity of the injuries to victims. In addition to the physical condition of the victims, the FGC must also consider the emotional state of the victims -- if they react in a terrorized and combative manner they risk their own lives and those of the firefighters trying to help them. The condition of victims must be considered by the FGC through all the phases of rescue: from the size-up the fire, to how it relates to the structure involved, predicting its spread and the spread of smoke and gases prior to control. The success of a rescue is determined by how well the search is carried out by the effectiveness of the fire ground commander's size-up.
