CDPH Lead Inspector/Assessor California State Practice Exam

Can thick diaper-type wipes be used to collect dust samples?

1. Yes

2. No

3. Only if they are dry

4. Only for certain studies

The correct answer is: No

Thick diaper-type wipes are not suitable for collecting dust samples due to their construction and the potential for contamination. The primary concern is that these wipes may not effectively capture dust particles in a manner that maintains the integrity of the sample. Proper dust sampling requires materials specifically designed to minimize contamination and ensure that the dust collected can be accurately analyzed for lead and other hazardous substances. Specialty wipes or materials specifically intended for lead sampling typically have defined properties that facilitate the collection of fine particles without altering or adding contaminants to the sample. In the context of rigorous regulatory or health standards for lead inspection and assessment, using inappropriate materials like diaper-type wipes could compromise the quality and reliability of the results, which is critical for maintaining safety and compliance with health regulations.
