Is sulphur dioxide classified as a flammable gas?

Is sulphur dioxide classified as a flammable gas?

• A. Yes, highly flammable
• B. Yes, at high concentrations
• C. No, not flammable
• D. Yes, but only at low temperatures

Answer: (C)

Sulphur dioxide is not classified as a flammable gas because it does not support combustion and has a high ignition temperature. Its chemical properties indicate that while it can react with certain substances, it does not easily ignite or burn in typical atmospheric conditions. This classification is based on its behavior in the presence of a flame or spark; it does not contribute to a fire or produce flames on its own. Understanding this property is crucial in handling and storing sulphur dioxide in various industrial and laboratory environments, ensuring safety protocols are in place to manage its toxicity and potential hazards rather than flammability.
