Kindergarten staircase design and evacuation distance

Quick answer：

The design of staircases in kindergartens should comply with local building codes and safety regulations. The evacuation distance refers to the minimum safe distance required from a point in the building to the nearest exit. This is to ensure that children can quickly and safely evacuate in case of an emergency. The specific distance requirements vary depending on the jurisdiction and the number of children in the building. It's essential to consult the relevant authorities or architects for accurate guidelines.
