What signal word must highly toxic products display?

Highly toxic products are required to display the signal word "Danger" to indicate their level of toxicity. This term is part of a system designed to communicate the risks associated with certain chemicals, making it immediately clear to users that these products pose a significant hazard if mishandled. The use of "Danger" alerts handlers and users to the serious nature of the product's toxicity, distinguishing it from other products that might use "Caution" for less toxic substances. Understanding these signal words is crucial for safe handling and application of pesticides, as it directs attention to the necessary precautions and safety measures needed when dealing with highly toxic materials. This clear categorization helps ensure that users are aware of the potential risks and can take appropriate actions to minimize exposure and incidents.
