How should a 150 lbs. gas chlorine cylinder be properly stored?

Storing a 150 lbs. gas chlorine cylinder vertically and secured to the wall with a chain is important for safety and structural integrity. Chlorine gas is highly corrosive and can be hazardous if there is a leak. By storing the cylinder vertically, you ensure that the pressure relief device functions properly, allowing any released gas to disperse safely. Securing the cylinder to the wall helps prevent it from tipping over, which could potentially cause damage or a dangerous situation if the valve were to break.

While storing cylinders in a cool, dark room can be important for many gases to prevent degradation or increase in pressure, it is not sufficient by itself for safe handling of chlorine cylinders. Similarly, placing them horizontally could lead to issues with the valve and make it more susceptible to accidental damage, while using an airtight container is impractical as it would trap gas and increase the risk of pressure buildup and leaks.
