     We all know how important human life is-it's priceless. It doesn't matter where you are from or what

the color of your skins is-all people are human beings. Firstly, we can tell you that the lives of your

relatives could depend on your ability to give first aid. If you think highly of human's life, this website is

for you! Here you can find information about first aid.

     The very first thing that you should do when you see an accident is to evaluate the situation and

prevent further dangerous incidents. First of all, you have to recognize what has happened and what the

dangers to rescuers and victims are. Think about how to take care of the victims.

     Helping usually takes place in very difficult conditions and injuries can be very bad. Therefore, you

cannot be too afraid of making mistakes to help. Sometimes you have to face the fact that regardless of

your actions and your efforts the victim's condition might not improve-he or she could even die. In some

cases even professional medical aid may not succeed. If you have done everything you think you should

do, you shouldn't feel guilty.

     Do not expose yourself to danger. Giving first aid can be dangerous. While trying to help a victim, do

not forget about your own safety. If something happens to you, you won't be able to help anyone.

     Call for help after you find out the condition of a victim. But remember if a victim faints due to

breathing failure caused by drowning, choking or poisoning, you should first take actions that help to

bring back the heart beat and breathing. While calling, talk shortly but clearly. Always provide the

following information: the location of the accident, the kind of accident, the number of the injured and

your full name and phone number and so on.
