Explanation:
Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. ... When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.). This process is known as oxidation.
