What does the term 'away' refer to in the valve-handling description?

• A. Purge valve turned away from the wearer
• B. Both valves turned away from the wearer
• C. Purge valve toward the wearer
• D. Both valves toward the wearer

Answer: (B)

In valve handling, “away” means pointing the valve outlets and handles away from your body. The best practice is to orient both valves so they vent outward, away from the wearer. This minimizes the chance that any detected venting or a momentary purge could blow gas, moisture, or contaminants toward your face or eyes. With both valves turned away, you also keep the purge function clear of your breathing zone and maintain safer, more predictable handling as you don’t have to deal with venting directed at you. If the purge valve were toward you, any inadvertent discharge could blow toward your face, which is why that orientation is not preferred. Likewise, having one or both valves facing you would raise the risk of exposure and discomfort.
