What does the presence of a HEPA AFD help with during cleanup?

The presence of a HEPA (High-Efficiency Particulate Air) air filtration device (AFD) is crucial during cleanup operations, particularly in trauma and crime scene situations, because it significantly improves air quality. HEPA filters are designed to trap very fine particles, including bacteria, mold spores, and other harmful contaminants in the air. By using AFDs equipped with HEPA filters, it helps to ensure that the air being circulated in the cleanup area is free from particulate matter that could pose health risks to workers and anyone in the vicinity. This is particularly important in trauma situations where biological contaminants may be present.

While the device can assist with creating a vacuum and isolating areas of contamination, those functionalities are secondary to its primary role of improving the air quality during the cleanup process. Measuring moisture levels is not a function of HEPA AFDs; this would typically involve a different type of equipment designed for that purpose. Therefore, the correct answer focuses on how HEPA filtration actively contributes to making the environment safer by improving air quality.
