Heaters are necessity and that too room heater a must in the cold countries. They are nowadays replacing the old lousy fire places. They serve the same purpose but the most exciting part is that the fireplaces are mainly made of wood and they serve as wood burners but now these modern heaters are run with the help of electricity and can be hanged anywhere in the house and still you will get the same heat. The fire place that we had previously was lousy and needed and took a huge place to sit. Whereas the modern ones are sleek and smart in looks and can be hanged anywhere you want in your home.

The other facility of the room heaters is that they are very helpful in helping you keeping the house need and clean and not messy. The style and looks can be achieved without getting the tones of woods and the messy ashes. So going for this one is a stylish and smart decision. The establishment and maintenance charge of room heater takes more time and expenditure where as the modern heaters do not take time and rather has no maintenance charge. They are run with electric and hence there is low cost in running them also. They do not create huge smoke and can be get easily from anywhere in the market.

Are you worried on the right place to hang a room heater? Then let me give you the good news that it can be hanged in a really small place it may be a kitchen or a really small bathroom. You just choose a place and you will get to hang it. So go for a room heater and make your house hot and cozy in the chilling heat outside. Whether you accept or not they’re the need of the hour.

Knowing the Enemy

It is has been often said about military operations and sporting contests that success hinges on knowing the enemy. For firefighters the enemy is not another person, which means that rather than guess on tendencies or tells, the best firefighters have a keen scientific knowledge of what causes fire. Of all the elements found on earth the three that are the most important to firefighters are carbon, oxygen and hydrogen. The elements are common in household products such as paper, wood, cloth, plastics and flammable liquids.

Combustion occurs when oxygen rapidly combines with a combustible material to create heat. Heat is the release of energy that is the result of a chemical reaction. Solid materials are made up of tightly packed molecules. The tighter that the molecules are packed the more an object weighs.

Heated molecules start to move, and as the temperature increases the more rapidly they go. As the speed of molecules increase it becomes more and more likely that the molecules will combine with molecules of another element by colliding with those molecules. When combustion occurs the oxygen molecules in the air combine with fuel molecules and form oxides.

This is where the heat energy comes from. Fires should be considered energy, and proper fire training should treat fire as such. Thus it is important to teach how this type of energy is produced, transferred and most importantly reduced. All combustible objects contain potential energy, which is released as heat and as light after the substance is ignited.

Heat and temperature are not the same. Temperature is the measure of the average molecular velocity and it indicates the intensity of heat at a given moment and location.

Knowing why a fire started and how it is contained means understanding energy. Energy is never created or destroyed, it is only converted into another form. Heat energy is transferred to cool water, but the key to stopping a fire is starving it. Without access to oxygen all fires will die out. Know that could be the key to preventing a disaster.

Fire Safety Basics

As schoolchildren, we are usually taught the basics of fire safety. Slogans like “stop, drop, and roll” and “don’t play with matches” are common. As we get older, one science teacher or another might explain to us how fire works. But as adults, we sometimes forget exactly what makes a fire burn. Then, if we find ourselves in situations where fire threatens us, we might make the wrong decision – for example, we might throw water on a grease fire. With this in mind, let’s review some of the fundamentals of what happens when something burns. If we take any of the following elements away, we can extinguish the fire.

Heat

For fire to burn, heat is required. The heat can come from another burning material, a chemical reaction, or from a natural source. Heat is what sets off the chain reaction that causes whatever is burning to keep burning. Taking away the heat by doing something like throwing water on a fire can stop the chain reaction.

Oxygen

Fire also requires oxygen to burn. This is why we must be so careful in environments, like hospitals, where the concentration of oxygen in the air can exceed normal levels. In these conditions, fire can spread much more rapidly. If we cut off a fire’s air supply – by smothering it with a blanket, for instance – we can stop it.

Fuel

Perhaps obviously, a fire requires fuel to burn. The chain reaction that results in burning needs something to keep it going. Grease, wood, and paper are just a few examples of fuel that a fire can use.

Chain Reaction

Lastly, the chemical chain reaction in a fire makes it burn. Too complex to describe here, a fire’s chain reaction can be stopped with any of the above methods, or by a chemical method. For instance, if we spray a fire with halon gas, it will slow down the burning chain reaction enough to extinguish the fire.
