The initial man did not know what the fire was, but he must have seen that loss which could cause it. He must have seen lightning and a volcano for a long time before starting to use fire.
The fire was powerful and dangerous, and he was scared. The earliest fires can bother, but now we know that the fire is the result of a chemical reaction.
When the oxygen in the air is mixed with carbon and hydrogen in a fuel, then a chemical reaction occurs. In this process, energy is released in the form of heat and light.
This is what we call a fire. Three things are necessary to make fire-fuel, oxygen, and heat. There are some examples of wood, coal, cooking gas and gasoline fuel. Oxygen comes from the air.
This is the reason that, when you fly on the smelling paper, it often explodes in the flame. The third thing needed to make a fire is heat.
Fuels and oxygen do not make fire by themselves, otherwise, a newspaper or a stick in the newspaper lies
To burn fire paper or wood pieces on our own, we heat it before catching it. We usually do it with a light match.
A friend and Fire Fighters
Each fuel has a special temperature on which it starts to burn. This temperature is called ‘flash point’ or ‘kindling temperature’ of fuel. Sometimes it is said that fire is a good servant but a bad master.
This means that the fire is very useful as long as it is kept under control.
For example, we cook it for our food, warm our house in winter and generate electricity. But, on the other hand, if the fire is out of control then it can be very dangerous.
Thousands of homes and shops are damaged by fire every year. The vast areas of the forest have also been destroyed and hundreds have been killed or injured.
Three things are necessary to start a fire, there are three main ways in which there is a fire
Can be excluded.
In each, one of the three necessary for burning is removed. For example, we can remove the fuel. If there is no fuel to eat on the fire, then there can not be any irritation.
We often add fire more fuel for this Another way of firing is to prevent oxygen from reaching. No supply of oxygen means no fire. Small fires can be excluded with a salt blanket or a sack or can be ‘bothered’.
It prevents oxygen from reaching the burning material. Occasionally, carbon dioxide is used to extinguish the fire. This oxygen does not allow burning content.
The third way to set the fire is to remove the heat. If the temperature can be brought under the flash point, it prevents fuel from burning.
You fly on a vivid matchstick or a candle to burn it outside. In doing so, you bring down your temperature below the flash point of the hot air around the flame, and candle exits. Occasionally, water is thrown on the fire.
It absorbs heat from burning fuel and reduces the temperature. The water blanket also cuts the supply of oxygen, and the fire extinguishes.
Some fire cannot be kept out of the water. If the water is thrown on the oil fire, the oil will float on top of the water and the burn will continue.
It can be very dangerous because the water can swell faster, with it taking the burning oil and spreading it
Fire Water should not be used on fire due to electrical equipment.
The person who sprinkles the water can get an electric shock and can be killed. A carbon dioxide sprinkler machine is the best thing to fight with electric fire.
We spend lakhs of rupees every year to fight the fire. And we are trying to find new ways to stop the fire from getting out of control.
Well learned to control the fire and kept it for good use in your daily life. Long ago, there were no firemen. When the fire broke down, everyone became Fire Fighters.
People made the human chain (they still do when necessary) and passed a bucket of water from a well or pond. Now there are laws about building construction which ensure that the space between the buildings has been left to reduce the risk of fire.
Every new building, in particular, a public place, should ensure fire prevention norms. Band of special equipment Fayrfaiting workers, known as fire, to fire. Fire extinguishers are highly trained people.
They have many skills. He cut off the power supply to cut off the power supply, dangerous walls, spray broke water and other materials.
They are also trained in first aid so that they can help people suffering from burns or smoking effects. The discovery of fire and its uses adopted a systematic way to help you cope better with the nature of the earliest and gradually life.
Fire is still worshiped in many parts of the world. Fire is actually a friend, but as we know, when it gets out of control it can be a dangerous enemy.
