A world fire extinguisher was born in 1834. In London, a fire almost completely destroyed the ancient Palace of Westminster where the British Parliament building is located. Among the many fire watchers, there is one who is not doing nothing to rush to see the fire scene. He is George William Mambi. (2) Dry powder fire extinguishers are mainly used to extinguish the initial fires of petroleum and its products, combustible gases and electrical equipment. Born in Norfolk, Manby was a young army, officer to captain, and served as the chief of the Yarmouth barracks. This idle time allowed him to devote his time to the cause that strongly attracted him to save human life. Later, Manby turned his genius from ocean rescue to fire rescue. When a fire broke out, he was experimenting with fire protection clothing. His most remarkable and pioneering contribution was that he invented the portable compressed gas fire extinguisher. This fire extinguisher is a two-foot long, eight-inch diameter copper cylinder with a capacity of four gallons, which is basically the same as today's fire extinguishers. He placed the fire extinguisher in his specially designed trolley. He hoped that a patrol equipped with such a fire extinguisher would immediately extinguish the small fires at the fire site, thereby reducing the number of major fires.
