What does the term 'regularly handle' pesticides mean?

The term 'regularly handle' pesticides refers to the frequency with which an individual is involved in activities related to pesticides, such as applying, mixing, or transporting them. The definition implies consistent and recurring exposure to pesticide-related tasks. Therefore, the correct interpretation is managing or dealing with pesticides more than six days within a 30-day period, which indicates a regular pattern of handling these substances.

This definition is crucial for regulatory compliance as it helps determine the level of training, safety protocols, and licensing required for individuals working with pesticides. More sporadic handling, as suggested by the other choices, would not constitute "regular" handling and may not necessitate the same level of oversight or safety measures. For instance, handling pesticides only on weekends or during peak seasons suggests infrequency, while exclusive use of closed systems does not relate directly to the frequency of handling but rather to the method of application.
