The Fire Extinguisher is a portable fire fighting tool. Put chemicals in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers have different ingredients and are designed for different fire causes. Attention must be paid to avoid adverse effects and dangers during use.

The world's first fire extinguisher was born in 1834. In London, a fire almost completely destroyed the ancient Palace of Westminster, where the British Parliament is located. Among the many fire watchers, there is one who is not idling to see the fire scene. He is George William Manby.

Manby was born in Norfolk. He served as the commander of the Yarmouth Barracks as a young man from the army, officer to captain. This idle position allowed him time to devote himself to the cause of saving human lives that strongly attracted him. Earlier, he was keen on shipwreck rescue. He invented the pants-shaped lifebuoy and was the first to propose the use of lighthouse flashes to identify signals. Later, Manby turned his genius from marine rescue to fire rescue. When a fire broke out, he was experimenting with fireproof clothing. His most remarkable and pioneering contribution was his invention of a portable compressed gas fire extinguisher, which is a copper cylinder two feet long, eight inches in diameter and four gallons in capacity, which is basically the same as today's fire extinguishers. He put the fire extinguisher in his specially designed trolley. He hoped that a patrol team equipped with such a fire extinguisher would immediately extinguish the first small fire at the fire site, thereby reducing the number of major fires.

Fire extinguishing equipment is a kind of fire-fighting must-haves that are often ignored by people and show their skills when they are urgently needed. Especially in the high-rise buildings, the interior is decorated with a lot of wood, plastic, and fabrics. Once there is a fire, without proper fire extinguishing equipment, it may cause catastrophe.

The ancient fire extinguishers were very simple, nothing more than hooks, axes, shovels, buckets and the like. The first real special fire extinguisher was invented by the British captain and Norfolk Manby in 1816. It was just one or two drums filled with more than 1 liter of water and filled with compressed air.

By the middle of the 19th century, French physician Gallier had invented a portable chemical fire extinguisher. Mix the sodium bicarbonate and water in the barrel, and place a glass bottle with sulfuric acid in the barrel mouth. When in use, the firing pin pierces the bottle to mix the chemicals, produce carbon dioxide, and press the water out of the barrel.

In 1905, Professor Laurent of Russia invented a foam fire extinguishing agent in St. Petersburg, mixing aluminum sulfate with sodium bicarbonate solution and adding a stabilizer. After spraying, a foam containing carbon dioxide is formed, which floats in burning oil, paint or gasoline. It can effectively cut off oxygen and suffocate the flame.

In 1909, Davidson of New York obtained a patent for using carbon dioxide to press out carbon tetrachloride from a fire extinguisher. This liquid would immediately become a non-flammable heavier gas to smother the flame. Since then, a variety of small fire extinguishers such as dry powder fire extinguishers and liquid carbon dioxide fire extinguishers have appeared.
