Multiple Choice

What measure helps prevent contamination during application?

Backflow prevention is the key safeguard because it creates a barrier that stops contaminated pesticide solution from flowing backward into the clean water supply or back into the mixing and application system when pressure changes occur. By using anti-siphon devices, check valves, or air gaps, a system prevents reverse flow, protecting water sources, surfaces, and the worker from cross-contamination. Ventilation helps with air quality but doesn’t stop backflow; backspray technology relates to spray management and reducing exposure, not preventing reverse flow into the supply; direct exposure increases risk rather than reducing it.
