Define “acute exposure” in the context of pesticide application.

Acute exposure refers to a scenario where an individual is subjected to high concentrations of a substance—such as a pesticide—for a brief period. This type of exposure can occur during the application process, when a person may be exposed to a significant amount of the chemical in a short time frame, typically minutes to hours. The effects of acute exposure can be immediate and are often more pronounced compared to those that might arise from lower concentrations over a longer duration.

Understanding acute exposure is critical for pesticide applicators, as it highlights the importance of using personal protective equipment and following safety protocols to minimize the risk of adverse health effects. This definition emphasizes the potential for rapid onset of symptoms and the need for immediate action if exposure occurs.
