Which phrase must every pesticide label include for safety?

The phrase "Keep out of reach of children" is a critical safety measure that must be included on every pesticide label. This requirement emphasizes the importance of storing pesticides safely to prevent accidental poisoning or harm to children. It underscores the potential risks associated with improper handling of chemicals, especially those that may be harmful if ingested or inhaled. Including this phrase on the label serves as a reminder to users and caretakers to take precautions, ensuring that pesticides are not accessible to those who might be vulnerable, particularly young children who may not understand the dangers.

While the other phrases listed also represent important safety messages, they may not be universally mandated on all pesticide labels. "Use only as directed" is essential for indicating that the product should be applied according to label instructions but does not specifically address the safety of children. "Wear protective gloves" highlights the need for personal protective equipment, and "Avoid contact with skin" is important for user safety, but neither speaks directly to the necessity of preventing children's access to potentially dangerous substances. Hence, the inclusion of the phrase about keeping pesticides out of reach of children is a fundamental aspect of responsible pesticide use and safety practices.
