Which hazard class does propane fall into?

  1. Class 1 / Explosives

  2. Class 3 / Flammable liquids

  3. Class 2 / Flammable gas

  4. Class 4 / Flammable solids

The correct answer is: Class 2 / Flammable gas

Propane is classified as a flammable gas, which places it in Class 2 of the hazard classes. This classification is due to propane's physical and chemical properties, where it can easily vaporize and form an explosive mixture in air when released. Understanding the specific classifications of hazardous materials is crucial for the safe handling, transport, and storage of such substances. By recognizing propane as a flammable gas, individuals involved in handling or transporting this material can implement appropriate safety measures, such as ensuring proper ventilation and avoiding ignition sources. In the context of the other options, Class 1 refers to explosives, Class 3 pertains to flammable liquids, and Class 4 is associated with flammable solids, none of which accurately describe propane.
