How high is the exit sign from the ground?

The exit sign should be 300~500mm from the ground. Safety exits refer to the entrances and exits of stairwells used for the safe evacuation of people, or the exits directly leading to outdoor safety areas or relatively safe exits in a broad sense. For sudden disasters such as earthquakes and fires, people need to leave buildings and go to safe areas. Usually, the emergency exit indicator light is attached to the corner of the passage to help people find the safe passage and leave the scene quickly. In order to evacuate people quickly and safely, transport valuable materials and reduce fire losses, it is necessary to design enough safety exits when designing buildings. Safety exit is of great significance in the field of safety technology.
