Abstract: It is difficult to imagine the fatalness
that faced by firefighters. They may lose their lives at all times. At present,
the fire helmets and fire suits developed by other countries are not possible
to ensure safety of firefighters fur- thest. In 1993, 7 fire fighters died in a
fire in Hengyang, while more than 250
firefighters sacrificed in “9.11” event that happened in the WorldTradeCenter in New York, the USA. In late December 2007, the
fire fighters extinguished the fire at a temperature of below −20˚C in the TradeCenter in Uulumuqi, Xinjiang and in that case, water would switch to ice very quickly.
There are endless examples like these. Why the fire fighters can sacrifice
themselves to rescue the lives and properties? Can the fire fighters protect
themselves as much as possible while saving lives and properties? There is only
one life for each person. What does sacrifice mean to their families? This
article contains many original ideas. If the ideas can be achieved, all of them
will be original innovation.
