On a pesticide label, which term defines the protective equipment that must be used by the applicator?

The term that defines the protective equipment that must be used by the applicator is personal protective equipment (PPE). This designation on a pesticide label indicates the specific clothing and gear that an applicator should wear to minimize exposure to the chemicals being handled. PPE can include items such as gloves, goggles, respirators, and protective clothing, and is critical for ensuring safety when working with potentially harmful substances.

The other terms listed serve different purposes: the EPA number refers to the unique identification assigned to a pesticide product by the Environmental Protection Agency, ensuring that it is registered and meets safety and efficacy standards. REI, or restricted entry interval, is the time period that must elapse after pesticide application before unprotected individuals can enter the treated area. The active ingredient refers to the chemical component of the pesticide that is responsible for its effectiveness. Each of these elements provides essential information but does not specifically address the need for protective equipment like PPE does.
