1. FOREWORD 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. 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.
