What is the common shipping container for liquid chlorine?

The correct answer encompasses all the options provided because each of them represents different sizes or capacities in which liquid chlorine can be stored and transported.

Liquid chlorine is commonly shipped in various forms to accommodate varying needs in quantity and application. The one-ton cylinders are standard shipping containers that hold 2,000 pounds of liquid chlorine, making them suitable for larger scale operations, such as municipal water treatment facilities. The 150-pound tanks are used for smaller applications and allow for easier handling and transport in scenarios where only a limited quantity of chlorine is required.

The diversity in container sizes helps ensure that facilities can procure liquid chlorine in volumes that best fit their operational requirements. Therefore, because these different types of containers all serve the purpose of shipping liquid chlorine, the answer reflects that this is indeed a versatile aspect of chlorine transportation.
