Are you aware that you can lose all your personal belongings in a single fire? It's very sad when fire strikes your home. You lose everything. You do not have a chance to save many belongings. You will be considered lucky if you escape with your life.
A person's home is a very private piece of his or her existence. People have been known to struggle for their entire life just to accumulate sufficient material riches and built comfortable shelters for themselves. We can experience a tremendous sense of loss if our homes have been razed to
ground by a fire.
Fires know no bounds. We hear so much of this happening in news. Small children and aged persons getting trapped inside while a house is on fire. We see live footage on television showing people jumping out from 3-storey buildings and getting injured. We see terror in their eyes as they make a desperate effort to avoid being burnt alive. We come across stories of people being suffocated by thick smoke from a fire.
Death, injury and material loss is result of fires in homes. It is matter for everyone to take seriously.
Yes, home is as safe as you make it to be - if you take steps to prevent fires from occurring in first place.
Fire can also be a friend or a foe to mankind. Fires have been used for keeping warm, for cooking, for lighting, and so on. If it were not for discovery and utilization of fire, mankind will have a very hard time surviving in cold reaches of Earth. Our early ancestors use fires to ward away wild animals.
Food tastes better when cooked or warmed up on a fire. Farmers clearing fields of weeds have also used fire. Many scientific discoveries are obtained by using heat from fires.
Internal combustion engines, steam boilers, make use of engineering principles of combustion. Engineers and scientists have studied how to harness heat from fires for energy generation.
Fire is a true friend if you know how to use it well. The benefits to mankind are many. Sometimes we forget that it can also be very dangerous.
There is a saying, "It takes a tree to produce one million matches, but it takes a match to destroy a million trees". That's power of a fire. It can also destroy tremendously. It can go out of control. Efforts must be made to tame it.
There should not be any doubt in minds of people. Fire is a boon to mankind. But it needs to be controlled well in order to use it.
People who makes use of fire, (that includes all of us), must know nature of a fire, and how a fire can start. It is a fundamental rule to understand what we are dealing with.
In order for us to use fire properly, we should know something about how a fire can occur. People who have a natural fear of fire usually do not know much about fires. If they know how a fire can start, they will not fear it as much, but rather treat it with respect. The more you find out about fires, better you will be at preventing it from going out of hand.
Starting a Fire
How a fire can start?
In order for a fire to start, three conditions must be met, and they must be present together. The conditions are heat, fuel, and oxygen. If you take any one of them away, a fire will not occur. It is called "Fire Triangle".
The Fire Triangle principle is used in all fire prevention and fire fighting measures. It is very simple. Remove any one of three, and you will not have a fire. Put all of them together and you will have a fire or even an explosion. An explosion is just a rapid burning of a fire.
The three components of a Fire Triangle are heat, fuel and oxygen. The components can appear in many forms and it important for those of us who want to adopt fire prevention measures to look carefully.
Sometimes, people do not realize that all three are present until it becomes too late. For example, a tiny electrical spark that can become a source of heat often cannot be seen at all. Sometimes, even when three conditions are present, energy of heat may not be sufficient to cause a fire.
As with all accidents, when nothing terrible happens, people tend to get careless. Why worry? It did not happen last time, it will not happen now. What they do not realize is that sometime there is not sufficient heat to vaporize fuel.
And fuel does not have to be petrol or kerosene. A piece of wood is combustible when it becomes heated enough. Cloth and paper are also fuels for a fire. The plastic chair in your dining room can be a fuel. In fact all organic materials can burn if it is hot enough.
Oxygen is always present in our atmosphere. In fact we thrive on oxygen in air to live. Oxygen occupies about 21 percent by volume in air, rest being Nitrogen. So in normal conditions, this part of Fire Triangle will always be present and is very difficult to avoid having when we plan our fire prevention measures in our homes. It will be more relevant when we want to stop a fire that has already started. In this case, one of ways to break Fire Triangle is to remove oxygen. There are ways to do this, one of them is by blanketing or smoldering.
However, in our planning for fire prevention, we can look at ways of reducing chances of oxygen rich atmosphere forming anywhere around fuel and heat. This has been known to start fires rapidly.
Everybody knows that heating can cause fires. However, we must not be unduly alarmed if there are sources of heat around us. We simply cannot avoid heat. In fact we use heating for our own benefit. Simply put, we must treat heat and fire with respect. We should also study mechanism of a fire.
