For maximum safety, flexible metallic connectors must be limited in length when used with which type of containers?

Flexible metallic connectors are designed for specific applications and their length is regulated to ensure safety and operational effectiveness. When used with larger propane containers, such as 2000-gallon containers, it becomes particularly critical to limit the length of these connectors. Longer connectors might introduce risks such as increased potential for mechanical damage, strain on the connections, and issues related to vibration or thermal expansion.

The limitation in length is a safety measure to reduce the risk of leaks or other failures that could result from improper handling or installation. With larger containers, the consequences of a failure could be much more severe, affecting not only the immediate area but also the overall safety scenario. By adhering to these guidelines, operators can ensure that the connectors maintain their integrity and function as intended, thereby minimizing the dangers associated with propane systems.
