What is one reason the U.S. EPA may classify a pesticide as a restricted use pesticide?

The classification of a pesticide as a restricted use pesticide by the U.S. EPA is primarily based on its potential risks to health or the environment. In this case, a significant dermal hazard means that the pesticide can cause serious harm through skin contact. This concern is heightened for applicators who may be exposed to the chemical more frequently than the general public. By designating a pesticide as restricted use, the EPA aims to limit its application to certified individuals who have received specialized training to handle such risks safely.

The other choices either do not relate directly to safety concerns or the regulatory framework under which pesticides are classified. For example, a pleasant scent or being classified as organic doesn’t necessarily indicate any harmful effects associated with use. Additionally, having a high boiling point is a physical property that does not reflect the toxicity or the potential hazards posed by the pesticide to human health or the environment. Thus, the assessment of dermal hazards aligns directly with the EPA's mission to protect public health and ensure safe pesticide usage.
