What is the first step in cleaning pesticide application equipment?

1. Fill the tank with a cleaning product

2. Drain sprayer tank and lines

3. Rinse the system for at least 5 minutes

4. Remove nozzles, screens, and strainers

The correct answer is: Drain sprayer tank and lines

The first step in cleaning pesticide application equipment involves draining the sprayer tank and lines. This initial action is crucial because it ensures that any remaining pesticide solution is fully discharged from the equipment. Effective cleaning starts with eliminating the bulk of the pesticide residue, as leftover product can contaminate the cleaning solution and create additional risks. By prioritizing the draining of the tank and lines, operators minimize potential health hazards and the chance of accidental pesticide mixing. This approach also prepares the equipment for the subsequent cleaning steps, such as rinsing or using cleaning products, which would be less effective if residues are still present in the system. Properly draining the equipment is an essential practice for maintaining not only equipment performance but also environmental safety and compliance with pesticide application regulations.
