What is Hazard Class 2 classified as?

Answer: B — Non-flammable gases

Hazard Class 2 is specifically classified as gases, which are categorized into different groups based on their flammability and other hazardous properties. This classification includes non-flammable gases and flammable gases, both of which fall under the broader category of gases. In the context of this classification, non-flammable gases do not ignite and are typically under pressure in containers. Examples include carbon dioxide and nitrogen. Understanding this classification is crucial for emergency responders or anyone handling hazardous materials because it dictates the appropriate safety measures when dealing with these substances. The other options represent different hazard classes: flammable liquids are classified under a different hazard class, combustible solids pertain to solid materials that can catch fire and burn, and radioactive materials belong to a separate category concerning nuclear substances. Therefore, recognizing the correct classification for Hazard Class 2 is essential for proper identification and handling of these gases.
