Which action is correct before cleaning spray nozzles?

• A. Clean nozzles by blowing compressed air only
• B. Move to a safe area and use a nozzle brush to clean nozzles
• C. Do not clean nozzles
• D. Use water to rinse while attached to sprayer

Answer: (B)

Before cleaning spray nozzles, switch off the sprayer and relieve any pressure, then move to a safe area. Use a nozzle brush to physically scrub the nozzle and its orifice to remove buildup. This controlled, hands-on cleaning minimizes exposure to pesticide residues, prevents creating airborne droplets, and helps maintain proper spray patterns. Using compressed air can push residues into the air and around you, which is dangerous; cleaning while the nozzle is still attached to the sprayer or rinsing with water in place can cause backflow, leaks, or unintended spraying.
