The correct answer is: 1

In the context of dust sampling within a management office, if the area is less than 400 square feet, one sample is required to adequately assess the presence of lead dust. This sampling procedure is based on established guidelines that aim to ensure a representative analysis of the area being evaluated. The process involves collecting a single dust sample from an appropriate location that can capture potential lead dust contamination, ensuring that the results will accurately reflect the lead dust levels in that space. Sampling more than one time in a smaller area would not necessarily provide additional valuable information and could unnecessarily complicate the analysis. Thus, in spaces under 400 square feet, a single sample is sufficient to meet regulatory requirements and maintain effective lead management.
