Otis launches classes to guarantee safer escalator rides

Hao Yiran, 8, never thought that the safety class she volunteered to teach could be so meaningful. After several escalator-related incidents happened in China in recent years, she said it is important for kids to know where the stop buttons are.

"I wouldn't have known it was wrong to jump on and off when taking escalators, if I were not a volunteer," she said. "But it is very dangerous."

Hao and her parents have volunteered to teach 16 elevator safety classes to more than 500 teenagers and preschool kids in Tianjin since 2013.
