What is an appropriate cleaning method for dust sampling?

Using approved ASTM wipes as a cleaning method for dust sampling is correct because these wipes are specifically designed to collect dust samples safely and effectively without leaving behind residues that could affect results. ASTM wipes meet established standards for the collection of airborne particles and lead dust, ensuring accuracy and reliability in the sampling process.

In contrast to other cleaning methods, ASTM wipes are validated for lead dust sampling and are more effective than damp cloths, which may not have the same specific protocol for lead sampling. Wet mops can introduce additional moisture that could interfere with the weight of the samples, while vacuum cleaners without filters can disperse particles back into the environment, potentially contaminating the area or skewing sampling results. Therefore, the use of ASTM wipes is the best practice in lead dust sampling to ensure compliance with regulatory standards and reliable data collection.
