I already have a huge amount of valuable experience.Why did you join the British Red Cross?I've always been interested in first aid, so when I saw some Red Cross volunteers at a local event I went over for a quick talk. After hearing what they had to say, I jumped_at the chance of joining.What's the big attraction?As soon as you've treated an injured man, you will never look back.

BDoctors in hospital emergency rooms (急诊室) often see accidental poisonings (中毒). A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a product meant to kill insects. These are common causes of accidental poisoning.In cases like this, seek medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.Millions of people know how to give abdominal thrusts (腹部按压) to save a person choking on something trapped in the throat. The American Red Cross says a rescuer should first hit the person on the back five times between the shoulder bones. If the airway is still blocked, the Red Cross suggests pushing hard five times along the victim's abdomen. You can do these abdominal thrusts by getting directly behind a sitting or standing person.The Mayo Clinic health centers suggest several steps if bleeding (出血) is severe. First, if possible, remove dirt from the wound and press on it with a clean cloth or piece of clothing. In the past, people were advised to stop severe bleeding with a tourniquet (止血带). But experts now say tourniquets are dangerous because they can crush (挤压) major arteries and nerves. If a wound seems infected, let the victim rest. Physical activity can spread the infection. Treat the wound with a mixture of salt and water until medical help arrives.To learn more about first aid, ask a hospital or an organization like a Red Cross or a Red Crescent Society for information. Training may be offered in your area.If you know first aid methods, you can be calmer and more helpful in case of emergency.语篇解读：本文是一篇说明文，告诉读者一些实用的急救措施。
