There is a Malay proverb says, "A small fire became friends, when the fire grows it will become our enemies" or in equivalent English proverb, "A small leak will sink a great ship." Malay proverbs are a word that is consistent with the use of fire in daily life. While fire is a necessity in daily life, it can be dangerous if not properly controlled. Fires are a chemical reaction in which heat and light are generated, which in turn produces smoke. Fire will only happen if there are three elements that combine to help fuel the flame, such as wood, paper and oil, air to supply oxygen and temperature or heat to generate heat or flames. The picture shows a triangle of fire where all three elements combine to produce a fire. There is a saying that "Prevent Is Better Than Treating". The question now is "How do you prevent a fire, if you don't know the cause". Therefore, it is necessary to understand how a fire can occur.
