Which task is associated with Class 8 corrosives?

Class 8 corrosives are defined by their ability to cause destruction of living tissue or severe corrosion of materials upon contact. The correct answer emphasizes the dual nature of these substances: they not only disintegrate contacted tissues but can also react with water in a potentially hazardous way. This characteristic highlights the significant danger posed by Class 8 corrosives, as they can lead to serious injury or material degradation, which is critical information for safety and handling procedures.

In contrast, other options suggest safe handling practices or limited danger, which misrepresents the true nature of these substances. The option that states they are only harmful in high concentrations fails to acknowledge that even small amounts can still cause serious harm. Similarly, the notion that they are safe for direct skin contact ignores the immediate hazards they present. Lastly, the idea that they do not cause damage to metals is inaccurate, as many corrosives can severely corrode various metals, making proper identification and safety measures essential when handling such substances.
