Background introduction
It’s important to first understand that escalators are large pieces of equipment that they provide convenience to people, they are also lethal, they are killing people, and they are maiming children.
For example, consider the horrifying and tragic escalator accident caught on tape earlier this year in China where a mom died saving her young child after an escalator panel gave way. This incident sparked increased coverage of tragic escalator accidents occurring throughout China over the course of just a few short days. A man in Shanghai lost his leg. A one-year old boy’s arm was severely injured. A six-year old injured his foot. A mother lost her life. Then more recently in October, a four-year old boy died after falling and becoming wedged under a handrail.

Customer status
Because the escalator is easy to use, many people use it directly without or thinking of receiving professional training. Now through the network, we can also see some basic security tips, such as:
1. Make sure your shoes are tied before getting on an escalator.
2. Stand in the center of the step, and be sure to step off of the escalator at the end of your ride.
3. Always hold children’s hands on escalators, and do not permit children to sit or play on the steps.
4. Do not bring children onto escalators in strollers, walkers, or carts.
5. Always face forward and hold the handrail.
6. Avoid the sides of steps where entrapment can occur.
7. Learn where the emergency shutoff buttons are in case you need to stop the escalator.
