Texas Pesticide Applicator Practice Exam

What is the most common cause of pesticide poisoning among applicators?

1. Inhalation of fumes

2. Ingestion of residues

3. Skin contact

4. Eye exposure

The correct answer is: Skin contact

Skin contact is indeed the most common cause of pesticide poisoning among applicators. This occurs because many pesticides can be absorbed through the skin, especially if there are small cuts or abrasions. Applicators may not always use appropriate personal protective equipment (PPE) such as gloves or protective clothing, leading to direct contact with the pesticide. Understanding this mode of exposure is crucial for pesticide safety, as it emphasizes the importance of using protective gear and ensuring that applicators are informed about the potential risks associated with the chemicals they handle. Inhalation of fumes, while a legitimate concern, tends to occur less frequently than skin contact. This is particularly true when applicators use proper ventilation and other protective measures to minimize exposure. Ingestion of residues is typically less common than skin contact as well, usually resulting from improper handling or not washing hands before eating or drinking. Eye exposure can also happen but is not as frequent a cause of poisoning as skin contact, especially when appropriate safety measures, such as wearing safety goggles, are in place.
