What distinguishes a propane cylinder from a propane tank?

The distinction between a propane cylinder and a propane tank primarily hinges on their regulatory standards and intended use. Propane cylinders are regulated by the Department of Transportation (DOT) in the United States and Transport Canada (TC) in Canada, which designates them as portable storage units for propane. These cylinders are designed for safety, portability, and specific pressure requirements, making them suitable for uses such as camping, backyard grilling, or providing fuel for portable heaters.

In contrast, propane tanks usually refer to larger stationary containers that are installed at homes or businesses for long-term use. These tanks hold a greater volume of propane and are typically found in residential or commercial installations, providing a constant supply of fuel for heating, cooking, or powering appliances.

The other options do not accurately characterize the critical differences between cylinders and tanks. For instance, while tanks are generally larger, it's not the defining feature that distinguishes them from cylinders. Additionally, propane tanks are not exclusively for short-term use; they are often used for long-term storage and supply of propane. Understanding these distinctions can help technicians make informed decisions regarding propane storage and usage applications.
