What does the Flame over Circle symbol indicate?

The Flame over Circle symbol specifically indicates the presence of oxidizing chemicals. Oxidizers are substances that can enhance the combustion of other materials, making them more flammable. This symbol is part of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), which is designed to provide consistent information about chemical hazards through labeling and safety data sheets.

Understanding this hazard is crucial in environments where oxidizing agents may interact with flammable materials or reduce the ignition temperature of substances, potentially leading to increased fire hazards. Proper labeling with the Flame over Circle ensures that those handling such chemicals are aware of the risks associated with oxidizing agents and can take appropriate precautions.
