What do danger, warning, and caution signify on pesticide labels?

The terms danger, warning, and caution on pesticide labels indicate levels of toxicity and help users assess the potential hazards associated with the product. Each designation corresponds to the degree of risk that the pesticide poses to human health and the environment.

"Danger" signifies a high level of toxicity, meaning that the pesticide can cause serious harm or even be fatal with exposure. "Warning" indicates a moderate level of toxicity; while it can still be dangerous, the risk is not as severe as that classified under "danger." Lastly, "caution" implies the lowest level of toxicity among the three, suggesting that, while the pesticide can still pose risks, it is less hazardous compared to the others. Understanding these terms is crucial for safe handling, application, and emergency response related to pesticide use.

The other options, while they may be relevant in other contexts, do not accurately reflect the specific role of these terms on pesticide labels. Brand comparison, application techniques, and spillage guidelines pertain to different aspects of pesticide handling or use but do not provide important insights regarding toxicity levels.
