Answer:
Because;
If someone is injured and they need first aid help, then the person can help them with their injury.
For Example:
A kid was running around and they accidently tripped, the kid has small scratches and a bleeding knee. The kid goes to their parents, he asks his/her parents to help him with his minor injury. The parents take out a first aid kit and start to clean off the scratches and etc.
Technically, if the parents didn't know how the first aid kit works, then the kid wouldn't be able to get the help and stuff to help with his bleeding knee and his scratches.
Hope this helps ^^
