Where should the exhaust vent be located in a chlorinator room?

• A. Near the floor
• B. Near the ceiling
• C. Halfway up the wall
• D. At the chlorinator bell jar

Answer: (A)

Chlorine gas is heavier than air, so any released gas tends to settle toward the floor. Placing the exhaust vent near the floor pulls the chlorine away from breathing zones right at the level where it would pool, helping to quickly remove it from the room and vent it outside. A ceiling vent would miss the heavier gas that stays low, and a mid-wall or bell-jar vent wouldn’t effectively address room-wide ventilation. So, floor-level exhaust best protects workers by capturing and removing chlorine at its point of accumulation.
