What does the classification of Class 2 gases refer to?

The classification of Class 2 gases primarily pertains to properties related to pressure. This class encompasses gases that are either compressed, liquefied, or dissolved under pressure, and they can be found in several applications including industrial settings and consumer products. Understanding this classification is essential, as the behavior and handling of these gases are significantly influenced by the pressure they are stored under.

For instance, when gases are pressurized, they can exist in liquid form and transform upon release to atmospheric pressure, which can lead to hazards if not managed properly. Additionally, the characteristics of these gases determine the required safety precautions for transport, storage, and use.

Inhalation risks, asphyxiation hazards, and flammability are important considerations in the management of hazardous materials but are specific to particular types of gases or conditions rather than the overall classification of Class 2. Therefore, the most accurate understanding of Class 2 gases is linked to their pressure properties.
