1. Purpose
Fire extinguishing equipment is a kind of fire-fighting must-have that is often ignored by people and shows its skills when it is urgently needed.
Fire extinguisher
Fire extinguisher
. Especially in today's high-rise buildings, where large amounts of wood, plastic, and fabrics are used to decorate the interior, once there is a fire, without proper fire extinguishing equipment, it may cause catastrophe.
Ancient fire extinguishers were very simple, nothing more than hooks, axes, shovels, buckets and the like. The first real special fire extinguisher was invented in 1816 by the British captain and Norfolk Manby. 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 chemical substances, 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. He mixed aluminum sulfate with sodium bicarbonate solution and added a stabilizer. After spraying, a foam containing carbon dioxide was 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 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.
2. Origin
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 to the 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 person to propose using a lighthouse 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. This fire extinguisher was a copper cylinder two feet long, eight inches in diameter and four gallons in capacity, which was 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.
3.Fire suffocation method
Cover the burning material with incombustible or non-combustible substances such as sand, cement, wet sack, wet quilt; |
Spray spray water, dry powder, foam and other fire extinguishing agents to cover the burning material; |
Use water vapor, nitrogen, carbon dioxide and other inert gases to pour fire containers and equipment; |
Enclose fired buildings, equipment and holes |
Spray non-combustible gas or non-combustible liquid (such as carbon dioxide, nitrogen, carbon tetrachloride, etc.) into the burning area or on the burning material. |
