Roof Emergency Door / Bus

Roof Emergency Door
Roof Emergency Door

There always are some serious traffic accidents around the world every day. When the bus is rolled over or capsized, its windows are hard to be used as effective emergency outlet because of their position. Passengers can’t escape through them quickly and efficiently, causing large number of casualties. The Roof Emergency Door is designed particularly with consideration of this scenario. Two emergency doors are set at the top of the bus, which can be opened from inside and outside. When the bus rolls over, the alarming lights on the door are turned on automatically. Passengers may locate and open the door quickly, and escape through them.
