Why should you wear PPE when calibrating spray equipment?

• A. Because the equipment may have pesticide residues on it.
• B. To look professional.
• C. To avoid contact with water.
• D. Because PPE is optional during calibration.

Answer: (A)

Wearing PPE during calibration is about protecting you from exposure to pesticide residues that may be on the sprayer. When you calibrate, you handle the equipment, open tanks or lids, adjust pressure, and flush or test the lines—areas that can have pesticide residues from previous applications. The protective gear acts as a barrier to skin, eyes, and lungs, reducing the chance of contact or inhalation if any residues are present or become airborne during the process. Typical protection includes chemical-resistant gloves, eye or face protection, long sleeves and pants, and appropriate footwear, with a respirator if the product label requires it. The other reasons offered don’t address the chemical exposure risk at calibration and PPE isn’t optional for this task.
