Which words on a pesticide label indicate the relative acute toxicity of the product?

  1. Hazard words

  2. Caution words

  3. Danger words

  4. Signal words

The correct answer is: Signal words

The correct answer is "signal words" because these specific terms are used on pesticide labels to communicate the relative acute toxicity of the product to the user. Signal words categorize the toxicity level into three distinct groups: "Danger," "Warning," and "Caution." "Danger" indicates products that pose a high level of toxicity, implying that they can cause severe harm, while "Warning" suggests a moderate level of toxicity, meaning that the product can cause significant but less severe effects. Lastly, "Caution" refers to products with lower toxicity levels, indicating they can cause mild effects under certain conditions. These signal words provide immediate information about the potential hazards of using the pesticide, allowing users to take appropriate safety measures. Understanding the significance of these terms is vital for ensuring safe handling, application, and adherence to legal regulations surrounding pesticide use.
