Only a small number of office workers have been trained in basic life-saving techniques.
Just 33,526 of London's estimated 3.5 million workers signed up with St John's Ambulance and the British
Red Cross to learn simple first aid last year. The figures coming from a new report show that nine out of 10
people would not know what to do if a colleague was badly hurt, while 72 percent have never attended a
first-aid course.
Doctors describe the situation as appalling and have called for urgent training in schools and the workplace.
Training in first aid should start at an early age and should be taught to everybody at school. First aid is very
important because at best it can save lives and at worst it reduces pressure on hospital rooms. Employers get
anxious when a worker has had some sort of accident in the office or factory and rush them to the
hospital-even if all they require is a bandage.
Last year 20,000 Londoners were trained in first aid by St John's Ambulance, the leading provider in
life-saving courses, and 13,526 were trained by the Red Cross. According to St John's Ambulance, four out of
five parents do not know how to carry out mouth-to-mouth resuscitation (苏醒).
Nick Suggitt, training manager with St John Ambulance, said,"We are training just a tiny part of the number
necessary, and only touching the tip of the iceberg."
"Not enough people know how to save a life, and since many emergencies occur at home or at work, these
skills are often needed to save the life of a friend or a family member."
