Gas mixing or blending is a dangerous process that requires a careful procedure especially when dealing with combustible gases that require a thorough mixing process such as a Explosion due to highly pressurized gases or flames can occur if both gases are not mixed homogeneously with each other, for example oxygen with fuel. However, the risk of danger is high for both the filler and the user in many different ways which can occur due to the following reasons: If the pressure vessel, pipes or valves suffer damage or any kind of corrosion, it is a failure point of the structure. • Oxygen is a great supporter to support combustion. However, any contact with heat at an early stage with the presence of different concentrations of gases or highly pressurized gases would be a positive sign for the fire to burn vigorously if the oxygen concentration is high or equipment failure due to gas at high pressure in the presence of fire or heat in the form of explosion.• Injuries may occur in case of failure (explosion) due to loose parts or simply risk of asphyxiation leading to suffocation and consequently death. However, mixing /gas mixing has a vast number of methods and ways in which the process is carried out based on the use of different studies on different flows and the purpose of the apparatus in which the gas mixing process takes place. For example, the apparatus can be an oxygen cutting torch, the hose into which diving cylinders are filled under certain conditions such as specific pressure, concentration, temperature etc. Furthermore, the gas cylinders used for furnaces also have the gas mixing process. In conclusion, the gas mixing methods and apparatus vary from each other to meet the required task.
