In case of fire, rescue operations, search and rescue, or other emergency situations, it is necessary to call the "112" hotline. These situations include natural disasters such as earthquakes, floods, landslides, and other similar events. In the event of a fire or explosion, or if there is a risk of such incidents, you should also immediately call the hotline. If search and rescue operations are needed in water bodies or if you are trapped due to a locked door, an elevator malfunction, or a traffic accident, the "112" line must be contacted. Additionally, it is important to call if there is an accident at construction or industrial sites, or if there is a risk of an accident.
