What distinguishes a Class 2.3 gas?

A Class 2.3 gas is specifically categorized as a toxic gas. These gases can pose significant health risks to individuals who are exposed to them, even in small quantities. They may cause severe injury or death through inhalation or skin contact, which is why it's crucial to handle them with extreme caution and follow appropriate safety protocols.

Toxic gases differ from other classes of gases, such as flammable ones, which are classified under different headings due to their ignitability rather than their health impacts. While some toxic gases could also be flammable or oxidizers, the definitive characteristic of Class 2.3 is its toxic nature. Understanding that helps ensure proper labeling, transportation, and emergency response strategies to mitigate risks associated with exposure.
