Indiana Pesticide Applicator Core Practice Exam

What disadvantage is associated with emulsifiable concentrates?

1. Non-abrasive to equipment

2. Requires no agitation

3. Can penetrate skin

4. Safe for all surfaces

The correct answer is: Can penetrate skin

Emulsifiable concentrates present a unique challenge due to their ability to penetrate the skin. This characteristic is concerning because it increases the risk of dermal exposure to pesticides, which can lead to potential health hazards for the applicator. Unlike other formulations that might be less likely to seep through the skin, emulsifiable concentrates may allow active ingredients to be absorbed. Understanding this risk is critical for applicators, as appropriate personal protective equipment (PPE) must be employed to minimize the potential for skin exposure during handling and application. In contrast, some other options focus on advantages of different formulations. For instance, emulsifiable concentrates are known for their compatibility with equipment, generally requiring some agitation to ensure they mix well but not being abrasive. Although certain formulations may be safe for various surfaces, the penetration risk is a prominent disadvantage that necessitates cautious handling.
