What are essential elements of an equipment pre-use inspection?

• A. Cleaning the equipment after application only.
• B. Checking only the battery and hoses.
• C. Verifying hoses, seals, nozzle condition, calibration, safety devices, and checking for leaks.
• D. Inspecting only the exterior for damage.

Answer: (C)

Before applying pesticides, the most important idea is that the equipment must be checked to make sure it operates safely and delivers the correct amount. This means inspecting hoses and seals for cracks or leaks, checking nozzle condition for wear, clogging, or misalignment, and confirming calibration so the spray output matches the labeled rate and droplet size. It also includes ensuring all safety devices—like shutoffs, guards, and pressure-relief features—function properly, and looking for any leaks throughout the system. If any of these parts are damaged or out of spec, you can get improper application, increased drift, or exposure risks.

Why this option fits best: it covers the full range of critical components that directly affect performance and safety, not just a single area. Other choices miss key elements: focusing only on cleaning, or only on a subset like battery and hoses, or just exterior damage, neglects nozzle condition, calibration, and safety devices, all of which are essential for a proper pre-use inspection.
