True or False: The words "Keep out of reach of children" must appear on all pesticide labels.

The statement "Keep out of reach of children" must indeed appear on all pesticide labels, making it a true statement. This requirement is in place because pesticides are often hazardous substances that can pose significant risks to children if ingested or handled improperly. The inclusion of such warnings serves to promote safety and awareness, helping to minimize accidental exposure and potential poisoning.

This regulatory guideline aims to protect vulnerable populations, particularly children, who may be more susceptible to the harmful effects of chemicals due to their smaller body size and developmental stage. Therefore, the presence of this warning is a fundamental aspect of pesticide labeling aimed at ensuring public safety.
