What term is used in the code book to refer to DOT tanks?

The term "Cylinders" is used in the code book to specifically refer to DOT (Department of Transportation) tanks. This terminology is important because it distinguishes these tanks from other types of storage containers used for various purposes in the fuel handling industry.

Cylinders are designed to hold gases or liquefied gases under pressure, and they must meet specific regulatory standards set by the DOT to ensure safety and compliance. The term reflects the shape and function of these vessels, emphasizing their design for transport and safe storage of gaseous materials.

Understanding this distinction is crucial for professionals dealing with fuel storage and transportation, as it ensures adherence to safety protocols and regulations pertaining to the use of these specific types of tanks. Other terms, like "containers," "tanks," and "drums," may not accurately convey the specific requirements or design characteristics stipulated by the DOT, leading to potential confusion or misapplication of regulations in tank handling and transportation practices.
