What three items must be documented when collecting dust wipe samples?

The correct documentation when collecting dust wipe samples includes the size of the sampled area, the room where the sample was collected, and the specific component that was sampled.

This information is crucial because it provides context for the sample, making it easier to assess the potential risk of lead exposure in that particular environment. Knowing the size of the area helps in understanding the scope of the sampling effort and allows for comparisons with other samples. Additionally, documenting the room aids in identifying potential sources of lead contamination and tracking the conditions of different environments. Recording the specific component sampled (like floors, windowsills, or other surfaces) gives essential information about where lead dust might accumulate, which is vital for risk assessment and remediation planning.

Other options focus on aspects that may be relevant in certain contexts, such as cleanliness or type of dust, but they do not provide the fundamental details needed for comprehensive documentation as prescribed by regulatory guidelines. Keeping accurate and thorough records helps in ensuring that assessments are credible and that any necessary follow-up actions can be effectively implemented.
