What is a requirement for chlorine gas storage rooms?

• A. They must be completely airtight
• B. They must have ventilation systems
• C. They must have a window in the door
• D. They must be underground

Answer: (C)

Chlorine gas is a hazardous substance that requires careful handling and storage to ensure safety. One of the critical requirements for chlorine gas storage rooms is that they must have ventilation systems. Adequate ventilation is essential to prevent the accumulation of chlorine gas, which can be harmful if inhaled. It allows any potential gas leaks to disperse quickly, reducing the risk of exposure to workers in the area.

While an airtight room might seem like a potential safety measure, it would actually pose significant risks by trapping gas in the event of a leak. Proper ventilation provides a means for the gas to escape, reducing the chances of hazardous concentrations. A window in the door or an underground location does not necessarily contribute to safe storage, especially when compared to the necessity of a proper ventilation system. Therefore, the requirement for ventilation systems in chlorine gas storage rooms is a crucial safety measure in handling this toxic chemical safely.
