关键的一步 / the key step

关键的一步
关键的一步

THE KEY STEP is designed to avoid the danger of going downstairs for those who can’t see the steps , such as the pregnant, the blind, and the person with large package in arms, especially in the case of darkness in corridor. Usually, missing step and tumbling are caused by the misjudgement to the places of the first and the last step. The bulges on the first and the last step are made to indicate the places of these two steps, and eventually avoid the risk of missing step and tumbling.
