What is the requirement regarding the signal words on pesticide labels?

The correct answer emphasizes that pesticide labels must include the instruction "KEEP OUT OF REACH OF CHILDREN." This requirement is fundamental in ensuring safety around hazardous substances, especially given that pesticides can pose serious risks to children if ingested or improperly handled. Including this instruction on labels serves as a crucial warning and reminds users to take appropriate safety measures to prevent accidents.

The inclusion of this specific phrase helps to raise awareness about the potential dangers of pesticides, reinforcing the importance of proper storage and handling. Proper labeling is a regulatory requirement that aims to enhance public safety and protect vulnerable populations, such as children, from exposure to potentially harmful chemicals.

Other choices may address aspects of pesticide use or labeling, but they do not capture this essential safety directive that is universally required on pesticide labels. By ensuring that every pesticide label carries this instruction, authorities work to promote responsible use and mitigate risks associated with chemical exposure.
