What is the most common exposure route for a pesticide applicator?

• A. Inhalation
• B. Ingestion
• C. Ocular exposure
• D. Dermal

Answer: (D)

Skin contact is the most common way applicators are exposed to pesticides. During mixing, loading, handling equipment, applying treatment, or cleaning up, pesticides often come into direct contact with the skin, and the skin is a large, readily exposed surface that can absorb chemicals. This makes dermal exposure the primary concern in typical field tasks, which is why wearing proper PPE like gloves, long sleeves, coveralls, and impermeable footwear is emphasized and why decontamination after work (washing exposed skin and removing contaminated clothing) is a key safety step.

Inhalation, while important, usually occurs when pesticides become aerosols or vapors and is mitigated by respirators or other protection. Ocular exposure happens if there is a splash or drift, but it is less common as the main route compared to skin contact. Ingestion can occur if hands or contaminated objects are put in the mouth, but it tends to be a secondary route compared to direct skin exposure.
