Where should exhaust fans be located in a chlorine room?

Exhaust fans in a chlorine room should be located near the floor because chlorine gas is heavier than air. This characteristic allows chlorine to accumulate at lower levels when it is released into the environment. Locating the exhaust fans near the floor helps to effectively remove any unwanted accumulation of chlorine gas, ensuring that the area remains safe for personnel. This positioning prioritizes safety by preventing gas inhalation, as it encourages the immediate ventilation of any chlorine that may escape from storage containers or equipment.

In contrast, placing exhaust fans near the ceiling would not be effective since it would not address the accumulation of chlorine at lower levels. Similarly, positioning them in the middle of the room or near the entrance would not adequately manage potential gas build-up, which could put individuals at risk if a leak occurs. Thus, the correct location for exhaust fans is near the floor to ensure optimal ventilation and safety in chlorine handling areas.
