Round, usually on the ground. There is a box on it. There is also a person running in the box and a running arrow. In case of fire, you can run to a safe place along the evacuation sign.
Requirements for setting evacuation signs:
1. The direction sign of the evacuation indication sign should point to the nearest evacuation exit or safety exit.
2. The lower edge of the evacuation indication sign set above the safety exit or evacuation exit should not be greater than 0.3m from the upper edge of the door.
3. The distance between the center line of the evacuation indication sign set on the wall and the indoor ground should not be greater than 1m (the part that is not easy to install can be installed in the upper part), the distance between the self-luminous signs of light storage should not be greater than 5m, and the distance between the light evacuation indication signs should not be greater than 20m (for underground buildings, it should not be greater than 15m).
4. The evacuation signs set on the ground should be set continuously along the evacuation walkway or main evacuation route. In intermittent setting, the distance between self-luminous signs with light storage should not be greater than 1.5m, and the distance between evacuation signs with lights should not be greater than 3m.
5, light evacuation signs should be set up a protective cover made of glass or other non-combustible materials.
6. The battery can be used as a backup power supply for the light evacuation indicator, and its continuous power supply time should not be less than 20min (it should not be less than 30min when it is installed in high-rise civil buildings and underground buildings with a height exceeding 100m). After the working power supply is cut off, the standby power supply should be automatically connected.
