New device for building fire escape
As we know ,about 25000 people were killed
in building fire in the world every year .Though firefighters are working so
hard ,death is still going on in building fire . Why are there always so many
dead? Because ,so far there are not any professional self-rescue instruments
provided for the people . So when people are trapped in building fire ,the only
thing that they can do is just waiting for the firefighters` rescue . however
,sometimes death always comes before rescue .If there is a professional instrument
that can help people to escape from the building fire successfully and safely
as soon as possible by themselves , the death in building fire must be reduced
greatly . My invention is just a solution to this problem .
