Background

The first fire extinguisher in the world was born in one eight three four years, london, where a big fire almost completely burned the old wissmith mince in the united kingdom condominium. Among the many fire viewers, one who is not who catches up with the fire all the time is George Wellmann. The division of Manbi in Nofuke, the youth army, officer to Yunt, and the senior officer in Yuan-Maos barracks has the leisure time to make him have a strong incentive to save the human life. Earlier, he was keen on the rescue of a boat, invented a pants-shaped life ring, and was the first to propose a beacon flash identification signal. Manbi later turned his day from marine rescue to fire life saving. When a fire breaks out, he is conducting an experiment with fire protection clothing. His most prominent pioneering contribution was that he invented a hand-held compressed gas fire extinguisher, which was a two foot long, eight inch diameter, copper cylinder with a capacity of four gallons liters, essentially the same as today's extinguishers. He places the fire extinguisher in a specially designed trolley, and wishes to have a patrol team equipped with the fire extinguisher to immediately extinguish the initial small fire at the site of the fire, thereby reducing the number of major fire outbreaks.

The fire extinguisher commonly used at present has foam extinguisher, water smoke extinguisher, pressure handle formula dry powder fire extinguisher etc. also can use directly to spray the fire source with the water pipe and put out a fire, and above-mentioned fire extinguishing process all need hold the instrument of putting out a fire when catching a fire and operate in the scene of a fire, and the speed of putting out a fire is slow, and fire control effect is not obvious, must the people closely be close to the fire source simultaneously with the instrument of putting out a fire again during operation, and this has brought the hidden danger again for the life safety of personnel of putting out a fire.
