What effect is associated with the signal word WARNING on pesticide labels?

The signal word "WARNING" on pesticide labels indicates that the product is classified as moderately toxic. This classification is part of a standardized system established to communicate the level of risk associated with pesticide products to users and handlers. Products marked with "WARNING" are considered to have the potential to cause adverse effects upon exposure, but are less hazardous than those labeled with "DANGER," which signifies a higher toxicity level.

By understanding that "WARNING" denotes moderate toxicity, users can take appropriate safety measures when handling and applying the pesticide. This might include the use of personal protective equipment or ensuring that the area is well-ventilated. Recognizing the meaning of the signal words is crucial for safely managing risks associated with pesticide use, ensuring proper handling, and minimizing exposure both to the applicator and the environment.
