What is the minimum amount of wipes required when performing an inspection in a residence?

The correct amount of wipes required when performing an inspection in a residence is 12 wipes plus a blank, as this satisfies the regulatory requirements for lead inspections. The use of this specific number of wipes ensures that the inspector collects sufficient samples to obtain an accurate assessment of potential lead hazards throughout the property.

Collecting 12 wipes allows for a comprehensive sampling strategy, covering different surfaces in the home, which is critical in gathering enough information to effectively evaluate lead exposure risks. The addition of a blank wipe serves as a control in testing to ensure that the wipe results reflect any lead present in the environment rather than contamination that may occur during the sampling process.

Other options provide either insufficient or excessive numbers of wipes that do not meet the regulatory standards for conducting a thorough lead inspection, thereby potentially compromising the assessment's reliability.
