Primary search refers to the rapid and initial search operation conducted within a structure to locate and rescue any occupants who may be trapped due to fire or smoke. This critical operation is executed under the Incident Command System (ICS) and often involves the use of thermal imaging cameras (TIC) to enhance visibility in low-light conditions. Not to be confused with secondary search, which is a comprehensive assessment performed once the fire is under control and conditions are deemed safe for thorough exploration.
