As we know ,about 25000 people were killed in building fire in the world every year .Thought firefighters are working so hard to prevent them,death is still going on in building fires.
Why are there always so many dead? Because, so far there are not any professional self-rescue devices provided to the people . So when people are trapped in building fire, the only thing that they can do is just wait for the firefighters` rescue. However, sometimes death comes before rescue ..........
Give me a little help in getting my invention to market, and you may save you and your families .Building-fire always comes unexpectedly.
