Can a 12 gram cartride of co2 kill you if released in your house?

A 12-gram CO2 cartridge is unlikely to be lethal if released in a well-ventilated space, as the amount of carbon dioxide is relatively small. However, if released in a confined area with poor ventilation, it could displace oxygen and lead to asphyxiation, which can be dangerous. It's essential to ensure good ventilation and avoid accumulating large amounts of CO2 in enclosed spaces. If you experience symptoms like dizziness or shortness of breath, it's crucial to leave the area immediately.
