What does the signal word 'Danger' indicate?

The signal word 'Danger' is used on pesticide labels to indicate that the product is highly toxic by at least one route of exposure, such as inhalation, ingestion, or skin contact. This designation alerts users to exercise extreme caution when handling, applying, and storing the pesticide, as it poses significant health risks.

In pesticide safety, signal words serve as critical warnings that categorize products based on their toxicity levels. 'Danger' is the highest warning level, meaning that even small amounts can result in severe health effects or fatalities if not handled properly. Understanding this terminology is essential for preventing accidents and ensuring safe usage of pesticides.

The other options do not accurately reflect the implications of the signal word 'Danger.' For instance, 'Low toxicity' would pertain to products that are less harmful and would be marked with a different signal word, such as 'Caution.' Moderate irritation to skin might suggest a lesser risk and not warrant the 'Danger' label, while the option regarding safe handling does not convey the critical toxicity level indicated by the signal word 'Danger.'
