When handling a CO2 cylinder, what is critical to ensure safety?

Standing to the side when screwing a CO2 cylinder into the rifle is critical for safety because it minimizes the risk of injury in the event of an accidental discharge or if the cylinder were to accidentally be released under pressure. By positioning yourself to the side, you protect vital parts of your body, particularly your face and torso, from being directly in line with potential hazards.

This safety measure reflects best practices in handling pressurized equipment, as a sudden malfunction could lead to serious injury. It is always essential to maintain a safe distance and position when working with pressurized systems to ensure personal safety and that of those around you.
