In ASTM E 1792, the sampling product used is known as which?

• A. Wet Wipes
• B. Dust Wipes
• C. Ghost Wipes
• D. Swabs

Answer: (C)

The key idea here is recognizing the specific sampling device specified for wipe sampling of lead dust in ASTM E1792. In this standard, the surface dust is collected with pre-wetted wipes designed to pick up lead-containing dust in a controlled, repeatable way. Ghost Wipes are a branded, pre-wetted wipe product that is widely used for this purpose because their pre-moistened format and composition provide consistent dust collection on nonporous surfaces, which is essential for reliable lead analyses. Generic wet wipes or dust wipes are too broad in terminology and don’t denote the specific sampling product the standard calls for. Swabs refer to a different sampling approach (usually for very small or irregular surfaces), not the wipe method defined by E1792. So the sampling product known in this standard is Ghost Wipes.
