According to the information in today's headlines, under normal circumstances, residents in the same building can freely enter and exit the stairs, but in some specific circumstances, there may be restrictions. Therefore, when using stairs, we should pay attention to safety and abide by the relevant regulations of stairs.

If there are safety problems in the stairs, such as the stairs turning up, the railings loosening and rotting, etc. , it will cause great danger to pedestrians. At this time, check and repair immediately, and prohibit pedestrians from entering the stairs until the problem is solved. Secondly, in some public places, such as schools and libraries, it may be stipulated that only specific stairs or elevators can be used in order to better manage the flow of people and maintain the safety and hygiene of public facilities.
