What symbol is associated with safety in the SOS/JES system?

In the SOS/JES system, the symbol associated with safety is a cross. This symbol is widely recognized in various contexts as representing medical assistance and protection, often associated with first aid. The use of a cross emphasizes the commitment to safety and the importance of health protocols within the SOS/JES system.

Other shapes like circles, triangles, and squares may convey different meanings or concepts, but the distinctiveness of the cross as a symbol aligns it closely with themes of care and emergency response, which are fundamental to safety procedures.
