FIRE AS A FOE

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning.  Fire is a good servant but a very cruel master.  The negative effect of fire include hazard to life and property, atmospheric pollution and water contamination.

HAZARD TO LIFE AND PROPERTY


Uncontrolled fire burns homes and forests, and also kills people and animals.  Destruction of lives and property by fire is one of the almost daily disasters in the world.  Frequently when fire breaks out, humans are helpless and great losses occur before the fires are brought under control.
       
                               
ATMOSPHERIC POLLUTION

Fire produces a lot of harmful gases.  Particulate matter; carbon monoxide; atmospheric mercury; ozone-forming chemicals; and. volatile organic compounds in fire smoke air pollution irritate eyes, nose, and throat; long term exposure can cause cancer of these organs.  They can lead to asthma, emphysema, and other chronic lung diseases. They can cause allergic reactions in sensitive people.

                           

WATER CONTAMINATION

Water gets contaminated due to forest fires. Also the fire that breaks  out in oil tankers cause very large scale water pollution.

                                  

SOIL EROSION

The forest fire removes the protective vegetation in the land.  Subsequent heavy rainfall may lead to soil erosion by water.  Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorous which remain in the ash and are quickly recycled into the soil.  This loss of nitrogen caused by a fire produces a long term reduction in the fertility of the soil, which only slowly recovers as nitrogen is fixed from the atmosphere by lightning and by leguminous plants such as clover.
                          
                                 

DESTRUCTIVE WEAPONS

Fire is used for destructive purposes.  Most weapons are based on the principle of fire.  This applies to simple devices like handguns, artillery pieces and nuclear bombs.  The main destructive element in weapons or at least the trigger is fire-based.  In this case, it is not fire, which is danger in itself, but rather because it is used for destructive purposes by us.

                              


LPG ACCIDENTS

Incidents related LPG cylinder blast is more common nowadays.  While 97 lives were lost in accidents reported from Bengaluru, 91 were killed in Hyderabad. In all, 3,395 cases of gas cylinder burst were reported in India in 2013. And it is women who take the brunt, with 76.1% of victims being women
