What precaution should you take when handling a CO2 cartridge?

When handling a CO2 cartridge, it is essential to ensure that the end or base of the cartridge is not pointed toward you. This precaution is critical for safety because CO2 cartridges are under high pressure. If a cartridge were to malfunction, leak, or unexpectedly discharge, pointing it away from your body significantly reduces the risk of injury. Directing the cartridge towards an appropriate angle minimizes the potential for harmful incidents, ensuring that any accidental release of gas will not pose a threat.

Other precautions, while important, do not provide the same level of protection. For instance, over-tightening a cylinder may lead to damage or improper sealing, and standing directly in front of the cylinder while screwing it in increases exposure to hazardous situations. Likewise, while pointing the end of the cylinder at the ground may seem like a safe practice, it is not as effective as ensuring you do not point it at yourself, as the primary concern should always be to avoid directing the pressure towards any part of your body.
