Sagot :
For emergency. For example there was an accident and your place is far from the hospital you can use first aid treatment to reduce the danger.
First aid is important because it is the essential primary care given to an injured person hence the name, "first aid". If a person were simply thrown in the back of the ambulance on route to a hospital then it would be possible that he or she could bleed out where as if proper first aid were given they might have lived.
