What label would indicate a flammable liquid?

Answer: A — label featuring a flame symbol

A label featuring a flame symbol serves to identify flammable liquids, making it clear that the substance poses a significant fire hazard. This visual cue is vital in ensuring safety during the handling and transport of hazardous materials. The flame symbol distinctly communicates the primary danger associated with flammable liquids, allowing individuals to recognize and respond appropriately to the risks involved. Understanding and being able to identify such symbols is crucial in maintaining safety standards in environments where hazardous materials are present. The other labels—such as those with a shield, a check mark, or a snowflake—do not convey the specific risk of flammability and therefore are not representative of flammable liquids.
