What does breakthrough refer to in pesticide application?

Breakthrough in pesticide application specifically refers to the penetration of a pesticide through personal protective equipment (PPE). This concept is crucial for ensuring the safety of individuals applying pesticides, as PPE is designed to provide a barrier that protects the skin and respiratory system from potential exposure to harmful chemicals. When breakthrough occurs, it indicates that the chemical has compromised the integrity of the PPE, allowing the pesticide to reach the skin or be inhaled, which could lead to adverse health effects.

Understanding this term highlights the importance of selecting appropriate PPE based on its resistance to specific pesticides and regularly checking for any signs of wear that might lead to breakthrough. Proper training in utilizing PPE can significantly reduce health risks for pesticide handlers, making this a key aspect of safe pesticide application practices.
