What does a hazard sign representing fatality or toxicity mean?

The hazard sign representing fatality or toxicity is designed to alert individuals to a significant risk involved with a substance or situation. The correct interpretation, in this case, is the risk of severe health impact from exposure. This means that the substance can cause serious, potentially life-threatening health issues if proper precautions are not taken.

Understanding this sign is crucial in maintaining safety in environments where hazardous materials are present. It serves as a warning that exposure can lead to critical health repercussions, reinforcing the importance of using appropriate personal protective equipment and safety measures when handling or working near such substances.

In contrast, other options would indicate lower levels of risk. For example, skin irritation would suggest a lesser degree of health hazard, while mild toxicity implies that the substance may not have severe consequences. Likewise, the notion of safety with correct handling minimizes the real dangers and responsibilities associated with dealing with toxic materials.
