What is the international code to indicate stress?

The international code to indicate stress is commonly represented by the color orange. This coding is used in various safety and emergency contexts to signal that individuals or situations are under significant psychological strain or distress. The use of color coding helps in quickly and effectively communicating the status of individuals in emergency situations, allowing first responders and support personnel to prioritize assistance based on the identified needs.

While other options may refer to important concepts in safety or emergency management, orange uniquely encompasses the notion of indicating stress. The choice of color as a method of communication is significant, since it provides a visual and immediate understanding of a situation without requiring additional explanation. This makes it easier for teams to react appropriately when they see the color coded signal associated with stress.
