What does the signal word "Danger/Poison" indicate regarding pesticide toxicity?

The signal word "Danger/Poison" indicates that a pesticide has high acute toxicity. This labeling is a crucial part of pesticide regulation and communication, as it alerts users to the potential for immediate harm from exposure. When a pesticide is categorized with this signal word, it means that it can cause significant injury or death even with a small amount of exposure, whether through skin contact, ingestion, or inhalation.

The use of strong signal words like "Danger" in conjunction with "Poison" underscores the need for extreme caution when handling such substances. It is vitally important for anyone working with these chemicals to take appropriate safety measures, such as wearing personal protective equipment and ensuring proper ventilation, given the serious health risks involved.

Other options like moderate toxicity, lower toxicity, and environmental hazard do not apply in this case, as they refer to different levels or types of risk associated with pesticides that are not immediately life-threatening, differentiating them from the urgent warning represented by "Danger/Poison."
