Structural Pest Control Applicator Practice Exam

Which formulation is very hazardous because it is highly concentrated and absorbed easily by the skin?

1. Emulsifiable concentrate

2. Flowable

3. Fumigant

4. Granular

The correct answer is: Emulsifiable concentrate

The formulation that is very hazardous due to its high concentration and skin absorption capability is the emulsifiable concentrate. Emulsifiable concentrates are liquid formulations that can mix with water and are often used for their effectiveness in delivering active ingredients. Their concentration makes them potent, and when applied, they can easily penetrate the skin, leading to potential health risks for applicators if proper protective measures are not observed. In contrast, flowable formulations typically contain active ingredients suspended in a liquid, which may not be as readily absorbed through the skin. Fumigants are gases designed to penetrate and control pests in enclosed spaces but do not pose the same direct risk of skin absorption as emulsifiable concentrates when handled improperly. Granular formulations, being solid and often requiring specific conditions for effective pest control, generally present a lower risk of skin absorption compared to liquid formulations. Understanding the risks associated with different pesticide formulations is crucial for ensuring safety and effective pest management.
