Which hazard is indicated by the GHS symbol for an oxidizer?

• A. Explosives
• B. Environmental Hazard
• C. Corrosive
• D. Oxidizer

Answer: (D)

GHS pictograms show the type of hazard a chemical presents, and the symbol for an oxidizer is a flame over a circle. This warns that the substance can provide or release oxygen and promote or intensify combustion, potentially causing fires to start or spread more rapidly. That’s why this symbol designates an oxidizer as the hazard. It’s different from the explosives pictogram (bursting bomb), the environmental hazard pictogram (dead tree and fish), and the corrosive pictogram (hand and metal being damaged), which point to other dangers. Remembering that oxidizers boost burning helps you handle and store them away from fuels and prevent hazardous reactions.
