The standard procedure for taking a dust sample includes which of the following steps?

• A. Layout the sample area; measure 1/10 to 1 square foot; prepare the tube; place gloves on; properly wipe the sample area in an S motion with an approved wipe; place folded wipe in a sampling tube; clean up sampling materials.
• B. Layout the sample area; measure 1/4 to 1 square foot; prepare the tube; wipe in a circular motion; place wiped material in the tube; clean up.
• C. Only measure area after sampling; no wiping required.
• D. Use a vacuum-based particle collector to collect dust samples

Answer: (A)

In dust sampling for lead, the goal is to collect a representative, uncontaminated wipe sample. Start by laying out a defined sampling area and sizing it to the required area (about 1/10 to 1 square foot). Put on gloves and prepare the sampling tube so the wipe can be placed into it right after collection. Use an approved wipe and wipe the area with a clean, continuous S-shaped motion to lift dust from the surface. After wiping, fold the wipe and place it into the sampling tube, then clean up any materials to prevent cross-contamination. This sequence ensures the sample is collected consistently and preserved properly for analysis. Other approaches omit steps, use the wrong wiping motion, or rely on vacuum collection, which doesn’t meet the standard wipe-based procedure.
