True or False: The end fittings for flexible LPG hose must be permanently attached.

The statement is true; the end fittings for flexible LPG (liquefied petroleum gas) hose must be permanently attached. This requirement is critical for ensuring safety and preventing leaks in gas delivery systems. When flexible LPG hoses are used, any connection that is not permanently attached can pose a significant risk, as vibrations, movements, and thermal expansion can cause loose fittings to disconnect or leak. Permanent attachment methods help to maintain a secure seal, thereby reducing the likelihood of gas escaping and creating hazardous situations.

Older standards may have allowed for certain removable fittings, but contemporary guidelines emphasize permanence to enhance safety. This is especially important in marine applications, where the consequences of a gas leak could be catastrophic. Other options suggest conditions under which fittings might not need to be permanently attached, but those do not align with current safety standards that prioritize consistent and reliable connections for LPG systems.
