First Step in the burning process is

• A. Fuel and Oxygen Mix Properly
• B. Ignition
• C. Heat buildup
• D. Smoke release

Answer: (A)

Fire needs fuel, oxygen, and heat. The first step in the burning sequence is forming a combustible fuel–air mixture, where fuel vapors mix with the available oxygen. This mix must be in place so that, when energy is added, ignition can occur and combustion begins. Heat buildup and vaporization are necessary to produce those vapors, but cannot start combustion on their own without the proper fuel–air mixture. Ignition and the resulting flame come after the mixture is formed, and smoke is produced during burning.
