What does the hazard symbol featuring a flame over a circle represent?

The hazard symbol featuring a flame over a circle specifically represents oxidizers. Oxidizers are substances that can cause or enhance the combustion of other materials, which means they can promote or accelerate the burning process. This is particularly important in safety and handling contexts because oxidizers can create hazardous situations if they come into contact with flammable materials or if they are not stored properly.

In many situations, the presence of an oxidizer can be extremely dangerous because it can lead to fires or explosions that are more intense than what would occur with just a flammable material alone. Understanding this symbol helps workers to recognize the risks associated with handling such substances and the importance of proper storage and usage protocols to mitigate those risks.
