QAL Laws & Regulation Practice Exam

Which route of pesticide exposure is most frequent for pesticide handlers?

1. Oral (through your mouth)

2. Dermal (through your skin)

3. Inhalation (breathing it in)

4. Eye

The correct answer is: Dermal (through your skin)

Dermal exposure is indeed the most frequent route of pesticide exposure for pesticide handlers. This form of exposure occurs when pesticides come into contact with the skin, which is often unprotected during handling tasks. During activities such as mixing, applying, or transferring pesticides, handlers may inadvertently allow the substances to soak through clothing or come into direct contact with their skin. Dermal exposure is particularly relevant because the skin can absorb certain chemicals rapidly, potentially leading to significant health risks. While oral exposure can occur if handlers ingest pesticide residues, it is less common compared to dermal contact. Inhalation exposure may also happen, especially with aerosolized or volatile pesticides, but handlers are typically aware of the need for respiratory protection and may employ it more readily. Eye exposure is less frequent, as handlers often use protective eyewear to minimize this risk. Understanding the predominant route of exposure helps in crafting safety measures and training programs for handlers to reduce the likelihood and severity of exposure incidents.
