In the described valve-handling method, what does 'high' mean?

• A. Right hand goes high to the purge valve
• B. Left hand goes high to the purge valve
• C. Both hands go high to the purge valve
• D. Left hand goes to the cylinder valve

Answer: (B)

The key idea here is understanding how the valve-handling method defines which hand reaches the purge valve and in what position. “High” means you raise the hand up toward the purge valve so you can access and operate it smoothly without crowding the other controls. In this setup, the left hand is the one that moves up to the purge valve, leaving the right hand free to manage other parts of the equipment. This raises the left hand to a higher position so the purge can be depressed quickly and with good control, which helps keep the rest of the gear stable and within easy reach. If you were to use the other hand or a lower position, it could create awkward reach, potential interference with the cylinder valve, and slower, less controlled purging.
