When pressurizing your scuba system, which action should you perform with the SPG?

• A. Look Directly At The SPG To Confirm Full Cylinder
• B. Hold The SPG Facing Down Or Away From You
• C. Keep At Least One Second Stage Purge Button Depressed
• D. None Of The Above

Answer: (B)

When you pressurize the system, protect yourself from any possible gas jet or hose movement by keeping the SPG facing down or away from you. The SPG is part of the high‑pressure path, and if something releases or the hose shifts, having the gauge pointed away reduces the chance of gas, water, or debris blowing into your face. You can still watch the gauge to see the pressure rise, but keep its face oriented away so your face isn’t in the line of any potential discharge. Staring directly at the SPG or holding a purge button depressed isn’t a safe or necessary practice during pressurization.
