True or False: A pesticide with "danger" on the label must always include a skull and crossbones symbol.

A pesticide labeled with "danger" must indeed include a skull and crossbones symbol. This requirement is part of the labeling standards established to communicate the toxicity level of the substance. The presence of the skull and crossbones symbol alerts users to the heightened risks associated with the product, indicating that it presents a significant danger to health upon exposure. The use of these symbols is a critical safety measure designed to promote awareness and caution among handlers and consumers, making it clear that the pesticide in question poses serious risks when not handled properly. Therefore, the answer is true, as this requirement applies universally to products marked with "danger" regardless of their intended use in agricultural or other settings.
