Escalator accident

A boy in the third grade of elementary school was taken up with the escalator in the supermarket near my house the other day .This boy was unconscious critical now, and this accident was taken up on a large scale by the newspaper and the television news. Recently, the accident in the escalator happens frequently around the child. Even if it is convenient transportation for adults, but it is very scary for children. I think that it is important for children's parents or adults not to take my eyes off children　when taking an escalator.
