Which statement is true about cleaning pesticide equipment?

• A. Sloppy cleanup practices are one of the main causes of equipment failure or malfunction
• B. Cleaning is optional if equipment is in good condition
• C. Cleaning has no impact on safety
• D. Cleaning is only needed if residues are visible

Answer: (A)

Cleaning pesticide equipment after each use is essential to keep it functioning properly and safe to operate. When cleanup is sloppy, residues stay in lines, nozzles, filters, and seals, which can cause clogging, uneven spray patterns, incorrect application rates, and accelerated wear or corrosion. All of these issues can lead to equipment failure or malfunction, which is why thorough cleaning is described as a major factor in keeping a sprayer reliable. Cleaning isn’t optional, and you shouldn’t assume good condition means you can skip it. Residues can also pose safety and environmental risks, so it’s important to remove them even if nothing looks dirty. Some residues are invisible but still cause problems, so follow manufacturer and label cleaning instructions to ensure proper decontamination and safe storage.
