What does a Signal Word of 'DANGER/POISON' indicate?

The Signal Word 'DANGER/POISON' indicates a high level of toxicity in a pesticide product. Specifically, it is used for products that have acute oral LD50 values of less than 50 milligrams per kilogram (mg/kg). This means that very small amounts of the chemical can be lethal if ingested, highlighting the need for extreme caution in handling and using such products.

This designation is crucial for users to understand the potential risks involved and to implement necessary safety measures, such as wearing appropriate personal protective equipment and ensuring that the product is stored safely away from children and pets. The signal word serves as an urgent warning about the potential hazards associated with the chemical, guiding applicators to recognize the seriousness of its toxicity.

In contrast, other signal words convey lower levels of toxicity, such as 'WARNING' for moderate toxicity or 'CAUTION' for low toxicity, which would not evoke the same level of concern as 'DANGER/POISON.'
