What is the primary purpose of a signal word on a pesticide label?

1. To describe the chemical composition

2. To indicate the product's relative acute toxicity to humans and animals

3. To instruct on proper application techniques

4. To outline storage requirements

The correct answer is: To indicate the product's relative acute toxicity to humans and animals

The primary purpose of a signal word on a pesticide label is to indicate the product's relative acute toxicity to humans and animals. Signal words are categorized under three classifications: "Caution," "Warning," and "Danger." These words provide immediate and essential information about the level of toxicity associated with the pesticide, allowing users to understand the potential risk they may encounter while using the product. This understanding aids in making informed decisions about handling, applying, and taking protective measures when working with pesticides. Other aspects of the pesticide label, such as the description of chemical composition, application techniques, and storage requirements, are also important but serve different purposes. They provide information necessary for the safe and effective use of the product but do not specifically serve to convey the toxicological risk associated with pesticide exposure. The signal words are crucial for promoting safety practices and ensuring that users are aware of the potential dangers involved.
