Category 1 pesticides must be labeled with which signal word?

Category 1 pesticides are classified as highly toxic. Because of their potential to cause significant harm, the labeling requirements are stringent, and a distinctive signal word is used to convey the level of risk associated with these substances. The word "Danger" is employed on the labels of Category 1 pesticides to immediately alert users to the serious hazards they may face when handling or applying these products. This signal word is a crucial element of pesticide labeling, helping ensure safety by making it clear that immediate precautions must be taken.

In contrast, the other signal words relate to lower hazard categories. "Caution" and "Warning" are used for less toxic categories and do not convey the same level of urgency or risk as "Danger." The term "Alert" is not a standard signal word recognized in pesticide labeling classifications. Therefore, "Danger" accurately reflects the severity of risk associated with Category 1 pesticides and aligns with regulatory standards aimed at protecting users and the environment.
