What common hazard symbol indicates a corrosive substance?

The corrosion symbol, which features a test tube pouring a substance onto a hand, is specifically designed to indicate a corrosive substance. This symbol is a clear representation of the potential for severe chemical burns or damage to materials that can occur upon contact with skin, eyes, or other surfaces. It effectively communicates the dangers associated with handling such substances, emphasizing the need for precautions to prevent injury.

In contrast, the flame symbol represents flammable materials, indicating that the substance can easily ignite, while the biohazard symbol is used for biological hazards, such as infectious materials, indicating risks posed by pathogens or biological agents. The skull and crossbones symbol signifies acute toxicity, alerting individuals to substances that may be deadly in certain quantities. Each symbol serves a distinct purpose in labeling hazardous materials, ensuring that users are informed about the specific dangers they may encounter.
