  1. Which route of pesticide exposure is generally the most common for professional applicators?

    Answer: Dermal (through the skin)

    Skin contact accounts for the majority of occupational pesticide exposures, especially on the hands and forearms.

  2. When mixing a concentrated pesticide, at which stage is the applicator at greatest risk of exposure?

    Answer: Handling the undiluted concentrate during mixing and loading

    Concentrates are far more toxic than diluted spray, making mixing and loading the highest-risk task.

  3. An applicator experiences pinpoint pupils, excessive salivation, and muscle twitching after using an organophosphate. These are symptoms of what?

    Answer: Cholinesterase inhibition poisoning

    Organophosphates and carbamates inhibit cholinesterase, producing the classic SLUDGE symptoms and pinpoint pupils.

  4. What is the FIRST action an applicator should take if a pesticide concentrate splashes into a coworker's eyes?

    Answer: Flush the eyes with clean running water for at least 15 minutes

    Immediate and prolonged flushing with clean water is the standard first aid for ocular pesticide exposure.

  5. Which piece of information must an applicator provide to a physician or poison control center in a pesticide poisoning emergency?

    Answer: The product label, including the active ingredient and EPA registration number

    The label identifies the active ingredient and first aid statements doctors need to select the correct treatment.

  6. Chemical-resistant gloves used for pesticide handling should be made of which material rather than leather or cotton?

    Answer: Nitrile or other unlined chemical-resistant material

    Leather and fabric absorb pesticides and hold them against the skin, while nitrile resists penetration.

  7. A fumigation job requires respiratory protection. Before an employee wears a tight-fitting respirator, what must occur?

    Answer: Medical evaluation and fit testing under a respiratory protection program

    OSHA requires medical clearance and fit testing before tight-fitting respirators are used on the job.
