At what age is adult first aid applicable?

Adult first aid is applicable to individuals who are 8 years and older because they are considered capable of understanding basic first aid principles and demonstrating appropriate response measures in emergency situations. Training programs often recognize that children and pre-teens can grasp essential first aid concepts, such as calling for help, performing CPR, and understanding the importance of remaining calm in emergencies. This threshold reflects a balance between developmental maturity and the ability to act decisively in emergencies, empowering individuals to assist with first aid even at a younger age.

The other options represent ages typically associated with various stages of personal development or legal responsibility, but the established standard for adult first aid recognizes younger individuals' potential to contribute effectively to emergency response beyond just the adolescent years.
