Government statistics recently revealed that in the UK, more than 3,000 people a year experience electric shocks in their home. A smaller number are electrocuted(触电死亡) after contact with power lines outside the home. Electric shocks can cause a person’s heart or breathing to stop, can also cause burns and are potentially fatal. It is essential for people to learn basic first aid techniques to deal with such emergencies.
What to do?
1. If you are the first person to reach someone who has had an electric shock, don’t touch them!
2. If they are still holding the appliance that has given them the shock, unplug it or turn off the power at its source. Under no circumstances should you try to move the appliance with your hand!
3. If you can’t turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim(受害者) from the appliance or the power source. You may even be able to do this with a folded newspaper.
4. The victim must remain lying down. If they are unconscious, victims should be placed on their side. But ________________ if there is a possibility of neck or spin injuries unless it is absolutely necessary.
5. It is essential to maintain the victim’s body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation(恢复呼吸). Keep the victim’s head low until professional help arrives.
