Which duster position is correct for application by the technician?

• A. Duster A position
• B. Duster C position
• C. Duster D position
• D. Duster B position

Answer: (D)

The key idea is controlling where and how the dust is released to get even coverage while preventing drift toward you. The correct duster position keeps the tool at a practical working distance from the surface and at a slight downward angle toward the target area. This setup allows the dust to fall into cracks, crevices, and along edges rather than blowing past the target or back toward your face.

With this position, you can use a smooth, steady sweeping motion to spread the dust evenly over the treated surfaces. Keeping your elbow tucked in and your wrist neutral helps you maintain a consistent flow and avoid awkward angles that could cause clumping or gaps in coverage. It also reduces fatigue and keeps control of the application.

If the duster is held too high or at the wrong angle, dust drifts away or lands unpredictably, leading to under- or over-application. If it’s too close or misaligned, you risk overloading a spot or triggering clogging. The position shown in the diagram that provides controlled release, good coverage, and safe handling is the correct one.
