INTRODUCTION First Aid is not intended as a substitute for accident prevention. It still holds true that an ounce of prevention is worth a pound of cure@ but the point has not been reached where the cure is not needed. Prompt treatment is indeed a measure of prevention@ for if the right thing is done immediately a slight injury be prevented from developing into a serious one and in more serious cases the injured's life m~ be saved. It must also be remembered that first aid treatment is not intended to take the place of the doctor's services. Where there is a serious injury a doctor should always be called@ but there are times when he cannot reach the scene of an accident immediately and a few minutes delay maymean the loss of a life. When such an emergency arises a person trained in first aid is invaluable@ not only to the injured person@ but also to the community in which he lives. The trained first aid man know how far he can safely apply his treatment and will never attempt to do work that he knows should be left to the doctor. His duty is to put the victim of the accident in the best possible condition for further treatment when the physician arrives. The first aid man also uses his knowledge in the prompt treatment of slight wounds to prevent infection - injuries which might otherwise remain neglected with possible serious results.
