What is one purpose of controls implemented for gas layering?

One of the purposes of controls for gas layering is to increase air velocity and cause turbulence within the space. This is important in environments where different gases may stratify or layer based on temperature, density, or other factors. By creating turbulence and higher air velocity, these controls help to mix the layers of gas, ensuring that there is a more uniform distribution of gases within the area. This can prevent situations where certain gases become trapped in pockets, which could lead to safety hazards or inefficient operation of systems that rely on a uniform gas composition.

Creating turbulence is especially crucial in ventilation systems and industrial processes where the consistent mixing of gases is necessary for optimal performance and safety.
