What is the first step in the minimum wipe area for floors?

Wipe around the perimeter
Start at corner with wipe fully opened
Make a top-to-bottom pass
Fold the wipe in half

The correct answer is: Start at corner with wipe fully opened

Starting at the corner with the wipe fully opened is essential for ensuring that the maximum surface area is covered during the sampling process. This technique allows for a comprehensive collection of dust or particulate matter that may contain lead. By starting at a corner, the risk assessor can systematically work their way across the floor area, facilitating an organized approach to complete sampling. This method also helps to avoid missing any areas, as the assessor can ensure that they are progressing in a way that minimizes the likelihood of re-sampling already wiped areas. The act of fully opening the wipe enables it to have a larger surface area in contact with the floor, thus increasing the likelihood of effectively collecting lead particles. In contrast, wiping around the perimeter, making a top-to-bottom pass, or folding the wipe in half do not maximize the wiping efficiency in the context of collecting samples from floors. These techniques may either limit the amount of surface area being wiped or may introduce inconsistencies in the collection process.
