What does the signal word 'WARNING' signify on a pesticide label?

The signal word 'WARNING' on a pesticide label indicates that the product is moderately toxic. Pesticide labeling uses signal words to communicate the level of toxicity to users, emphasizing the potential hazards involved in handling or using the product. The classification system typically includes signal words such as 'CAUTION' for low toxicity and 'DANGER' for highly toxic substances, with 'WARNING' falling in between. This helps users to understand that while the product does pose risks, particularly if misused, it is not as dangerously toxic as those products labeled with 'DANGER.' Understanding these signal words is crucial for ensuring safe application and handling practices, thereby reducing the risk of harm to both humans and the environment.
