What is the primary reason for placing a chlorine exhaust fan at floor level?

The primary reason for placing a chlorine exhaust fan at floor level is because chlorine gas is heavier than air. This characteristic of chlorine means that when it is released, it tends to accumulate at lower levels rather than dispersing upward. By installing the exhaust fan close to the floor, it allows for the effective removal of chlorine gas from the area before it can pose health risks to workers or affect the surrounding environment.

Choosing the correct placement of the exhaust fan is crucial for safety, as it improves the ventilation process and helps to maintain air quality by directly targeting the source of potential chlorine accumulation. Proper ventilation measures mitigate the risks associated with chlorine gas exposure, which is essential in facilities that utilize chlorine for water treatment or disinfection processes.
