Which symbol on a pesticide label indicates that the product is toxic?

The symbol that indicates a product is toxic on a pesticide label is the skull and crossbones. This universally recognized symbol serves as a clear warning that the substance can cause harm or even be fatal if ingested or absorbed through the skin. The skull and crossbones is used to signify acute toxicity and is part of hazard communication standards that aim to inform users of the dangers associated with handling or using the pesticide.

In contrast, other symbols do not specifically denote toxicity in the same way. A triangle might indicate caution generally, while a circle could signify a less immediate hazard. A diamond is often associated with other types of hazard classifications, but it does not directly convey the same level of danger as the skull and crossbones, which unequivocally highlights that the product must be handled with extreme care due to its toxic nature. Understanding these symbols helps ensure the safe handling and use of pesticides, protecting both people and the environment.
