First aid signs are visual indicators that provide important information about the location of first aid supplies or the presence of trained personnel. These signs often feature a white cross on a green background, symbolizing medical assistance. They help people quickly identify where to go for help in emergencies. In addition to indicating first aid stations, these signs may also include instructions for basic first aid procedures, such as CPR or wound care. Understanding these signs can enhance safety in public spaces, ensuring that individuals know where to find assistance when needed.
