FIRE

FIRE

 is an exothermic oxidation reaction that progresses rapidly from a fuel accompanied by the onset of fire. 

Causes of Fire Occurrence : 

1. Combustible material - intensive goods, liquid or gas ( such as : wood, paper, textile, petrol, oil etc.)
2. Heat (temperature)  The environment has such a high temperature, (the heat source from sunlight, electricity ( Thermal mechanical energy (friction), Chemical reaction, Compressed air)
3. Oxygen (O2), The substance Acid (O2) is sufficient. The content of O2 is determined as a percentage the greater the oxygen content so the fire will turn more severe, whereas less than 12% oxygen levels will not arson fire. under normal circumstances oxygen levels ranging from 21% free air, the air has a pretty active burning.
