When performing maintenance repairs on a power sprayer that has not been cleaned out, what should you always do?

• A. Disconnect power before maintenance
• B. Spray away from body
• C. Check for leaks
• D. Wear protective clothing to avoid exposure

Answer: (D)

When maintenance involves equipment that may still contain hazardous residues, the priority is to minimize skin and eye exposure. Protective clothing acts as a barrier between you and the chemicals, reducing the risk of irritation, burns, or systemic absorption from any splashes or leaks that could occur during work on an unclean sprayer. This is why wearing chemical-resistant gloves, long sleeves, a coverall or apron, and eye protection (and often boots) is the safest default practice before you start. Disengaging power is also important to prevent accidental spraying, and checking for leaks is a good precaution, but neither directly reduces your exposure to residual chemicals as effectively as proper protective gear. Moving the body away from sprays helps, but without a protective barrier, exposure can still happen. Wearing protective clothing consistently addresses the risk of contact with residues, which is why it’s the best choice here.
