It's important to post safety instructions and advise tenants of proper procedures. For example, if passengers become stuck in an elevator, advise them to stay calm. Passengers need to know that there is plenty of air in the elevator. Caution them never to climb out of an elevator. There have been cases where people have fallen down the shaft trying to climb out of an elevator.
Escalators consist of an endless chain of moving steps.
Safety features include brakes that are automatically applied when the drive motor stops for any reason, and an automatic shut-off if the speed is too fast or slow. There are also emergency stop buttons located at the top and bottom of the stairways. The most common myth about escalators is that they don't require much attention. In truth they are six-ton moving machines with more parts than a Swiss clock. Many also believe that escalators can reach out and grab passengers.
