Fire - Useful And Damaging (Part 1)

By sis Leong Mei Ji


Fire is a chemical reaction that gives light and heat. It smells like burning wood, smoke, and ash, and the smell of it is caused by the chemical compounds called pyrolysis products. These chemicals are released when organic matter burns.


Usage


Physical fire


In uncountable noun usage, we say that the factory has been badly damaged by fire and it took more than two hours to stop it from burning.


You are fired!


What does it mean when your employer tells you that you are fired? It is an unsympathetic and merciless phrase that may be used by those with the power to hire and fire employees when the services of those under their employment are no longer required. In brief, you have been laid off from your work.


Someone is on ‘Fire’


What does it mean if we say that someone is on fire? It means that they are very enthusiastic, excited, passionate, eager, or zealous about something.


Humans have a close relationship with fire


Fire is a constant presence in our lives. While we have to be careful not to let it get out of our control, we also need to use it frequently for health, cooking, warmth, and life.


Destructive nature of fire


Fire is sometimes useful, but also very dangerous because it can cause houses, trees, and other things to burn to ashes. A forest fire can sweep through and destroy everything in just a few days. Even fire brigades and firefighters or even planes and helicopters cannot put out the fire. The fire that keeps us warm can also consume us. The fire that cook our meals can burn us up. The same fire that can warm our homes, can burn them down. However, it is not the fault of the fire.


Benefits of fire


Using fire to cook


Cooking is one of the most common applications of fire because it makes food pleasant and safe to eat. Cooking methods such as roasting, baking, burning, and searing are all used to make food easier to prepare and safer to eat. We can also utilize fire to purify and soften vegetables, eggs, and other food for human consumption by boiling them in hot water.


Fire provides light


Light, a byproduct of fire, enables us to find our way towards a destination at night. It also helps us to move about much more safely at nighttime.


Fire keeps us warm from the cold


When we stand near the fire at a fireplace, campsite, or burning bush, we get warm after some time because of the heat transfer.


Water purification


Using fire to boil water helps to purify the water. It is still one of the best ways to purify water that comes out of the tap in our home.


Controlling wildfires


The fire which can turn a forest into ashes nevertheless remains one of the most effective methods for containing out-of-control wildfires. One method of controlled burning is to burn ‘fire breaks’ ahead of a wildfire. Firefighters create long strips of burnt-off vegetation under controlled conditions. Firefighters keep it under control using fire trucks and firefighting pumps and suppress it before the wildfire gets too close. When the out-of-control wildfire arrives, it finds all the fuel in its path has been burned, causing it to flame out.
