Is sulfur dioxide (SO2) classified as combustible?

Sulfur dioxide (SO2) is classified as a non-combustible gas. This means that under normal conditions, it does not ignite and is not capable of sustaining combustion. Sulfur dioxide is produced by volcanic eruptions and industrial processes, particularly the burning of fossil fuels containing sulfur, but it does not burn itself. This characteristic is important in various industries, particularly when considering safety and handling protocols, as it helps to determine the appropriate measures needed to store and manage the substance without the risk of fire.

Furthermore, being non-combustible implies that sulfur dioxide does not contribute to fire hazards in the same way that flammable gases or liquids do, which is a crucial distinction for those working in environments where such gases are present.
