Iowa Pesticide Applicator Practice Exam

The materials chosen for the construction of a pesticide storage area floor are critical for safety and compliance. Plywood and carpeting are not suitable because they are porous, which means they can absorb spills and leaks of pesticides. This absorption can lead to contamination, deterioration of the materials, and difficulties in cleaning.

In contrast, nonporous materials like metal or concrete are preferred as they do not absorb chemicals and can be easily cleaned, reducing the risk of residual pesticide exposure and improving safety standards. The use of these materials helps to contain any spills, ensuring a safer environment for both handlers and the surrounding area. Therefore, selecting materials like plywood and carpeting for a pesticide storage area can present significant risks, which is why they should be avoided.
