Signal word "danger/poison" corresponds to which toxicity level?

The signal word "danger/poison" is associated with the highest level of acute toxicity in pesticide labeling. This designation indicates that the chemical poses a significant risk if ingested, inhaled, or absorbed through the skin, which aligns with the classification of Toxic 1. Products categorized as Toxic 1 are typically characterized by their potential to cause severe harm or death, which is why they carry the most alarming signal words. The use of "danger/poison" serves to immediately alert users to the seriousness of the substance, emphasizing the necessity for strict handling and safety measures.

Understanding the toxicity levels is critical for proper pesticide usage and safety precautions. Each toxicity level has specific signal words and classifications that determine how dangerous the pesticide is to humans and the environment. Lower toxicity levels correspond with less severe signal words like "warning" or "caution," but "danger/poison" clearly indicates that the use of such a pesticide requires heightened awareness and care. This classification system is essential for ensuring safe handling and compliance with regulations.
