Which signal word is associated with pesticide products classified as highly toxic by at least one route of entry?

The signal word "Danger" is specifically associated with pesticide products that are classified as highly toxic. When a pesticide product carries the "Danger" label, it indicates that it poses a significant risk to human health or the environment through at least one route of entry, such as ingestion, inhalation, or dermal exposure. This classification is part of the labeling regulations designed to communicate the level of toxicity and safety measures that must be taken when handling or applying the product.

In contrast, "Warning" is used for moderately toxic products, while "Caution" is reserved for those that are less toxic but still require safety measures during use. The term "Hazard" does not function as a classification signal word in this context but may be used in descriptions or to indicate specific dangers associated with a pesticide. Understanding the implications of these signal words is essential for safe pesticide use and handling, ensuring applicators and users are aware of the potential risks involved.
