An open letter to fire-officers of the world

No offence , but do you really care about your men ---- firefighters ? and what can you do to give your men more protection in their firefighting work ?

Yes , all kind of protective suits and instruments have been provided , but do you think it is enough care for your men ? and have you ever thought that you could give your men more care in another way ?

Generally speaking , all the danger to firefighters comes from the scenes of fire . For a storied-building fire , the more people trapped in the fire , the more risks firefighters would take , as we know , most of the firefighters who died on posts all died of this case .

In other words , we can say that the less people trapped in building fire , the less risks your men would take . If there are professional instruments that can help most people trapped to escape from fire timely and successfully ,and your men only need to rescue the old and the weak those who can`t carry out selfrescue , don`t you think it will be a good news for you and your men ?

Neither my patent is a protective suits nor a protective instruments for firefighters , but it `s obviously to see that my patent would give your men more care in another way . Would it be worth your a little attention ? anyway , I don`t believe that you will say : that is none of my business !

God bless you and your men !

A swim guidebook or a lifebuoy ?

Here is a simple question , if you fall into water uncarefully ,then what`s the most important thing you need ? a swim guidebook or a lifebuoy ? I think most people will give the same answer : A lifebuoy of course ! Why do the most people give the same answer ? Because there is a big difference between self-rescue on skill and self-rescue on instruments .

When we were children in school , we had been told that we should take actions of self-rescue in accidents , and we were required to do practice in it . However there are not professional self-rescuer in lives , when we are out of practice , skill of self-rescue is gone as well . But self-rescue on instruments is another thing , the instruments are always just there ,whenever you need them , they will service you at once . It`s timely , simple and reliable , and you needn`t do any professional practice in using them either . Common sense is OK !

So the most people give the same answer to this simple question .

An open letter to the firefighting experts and firefighting professionals

Hello ! every firefighting expert and firefighting professional . I am a Chinese inventor ,as a nongovernmental firefighting-tech worker ,I ask you two questions about selfrescue in building fires .

First , when people are trapped in a building fire , is it necessary for them to take actions of selfrescue ? and should be there any professional selfrescue-instruments provided?

Secondly ,if there should be some kinds of professional selfrescue-instruments provided, then what elements should the selfrescue-instruments have ?

No offence ，but to be frank . any firefighting experts who have never thought about the two questions above should be negligent .All the firefighting experts have thire duty to give people more and more safety in their lives.

Perhaps someone will retort ：“ there were many kinds of professional self-rescue gears earlily , such as rope-escape systems , escape ladders and so on . how can you say there are not professional selfrescue instruments ? and all these gears are perfect enough . People don`t get these gears for fire escape just because they do not care about their own lives . ”But have you ever thought why the rope-escape systems and escape ladders can`t be popularized as well as smoke-alerts and fire extinguishers ? Because if you take escape ladders as your selfrescue gears ,how can you be sure that you will never hurt the people who are also escaping at the same time below your floors ? people below your floors maybe hurted when you spread down your ladders .Another question ,you will never be able to stop the people below your floors who will take your ladders , when there are too many people on your ladders ,your ladders will be broken ………… All in one word ,there are too many un-definitive and uncontrolled things in using them as selfrescue gears .As to the rope-escape system , it is just a professional gear for those professionals (such as firefighters , climbers ,etc .) , the common people can`t use it without training . Besides ,if there are ten or more rope-escape systems in one place ( people may escape at the same time from every floors of the buildings), will the ropes be knotted or will they twine together ?

Surely, if you think it is impossible that there will be any kinds of feasible selfrescue instrumrnts for the people trapped in building fires , you would never thought about how to solve this problem either . But how do you conclude that there will never be any kinds of feasible selfrescue instruments ? There is a necessity ,there will be an invention to it , necessity is the mother of invention . On the other hand ,if you are trying to work out a solution to this selfrescue-problem , you should know clearly that what elements the solution should have , it is very important ,because it is the direction of your research work . Just like this , if you say you are looking for something ,but you don`t know what the things you are looking for would be like , then you will never find it !and you will miss it as well even if it is just in front of your eyes .

Drawing is the best selfvindication of an invention .As the drawings of a general machine device , there is not any difficulty in reading it , because drawing is the professional communication language of technician .I would never want to deceive , I just show my invention to the world and then let the world judge it .
