In what position must a fixed liquid level gauge on a forklift cylinder indicate the maximum filling level?

A fixed liquid level gauge on a forklift cylinder must indicate the maximum filling level in both vertical and horizontal positions to ensure accurate functionality and safety. This requirement is essential because it accommodates various usage scenarios where the cylinder may not always be in an upright position.

Having a gauge that is reliable in both orientations ensures that operators can accurately monitor the propane level in the tank regardless of how the forklift is positioned during operation, preventing potential overfilling or operational hazards. The gauge must be designed to consistently reflect the liquid level accurately, promoting safe handling and usage of liquefied petroleum gas (LPG) in diverse applications.

By ensuring the gauge functions correctly in different positions, this practice aligns with safety protocols outlined in NFPA 58, emphasizing the importance of maintaining proper filling levels and minimizing risks associated with LPG storage and usage.
