Mold Assessment Technician Practice Exam

What is the primary function of non-viable air sample collection?

1. To culture and grow mold samples

2. To enumerate and identify particles directly

3. To assess overall air quality

4. To measure humidity levels in the air

The correct answer is: To enumerate and identify particles directly

The primary function of non-viable air sample collection is to enumerate and identify particles directly. Non-viable sampling methods involve capturing mold spores and other particulate matter from the air using techniques such as impactors or filters. This process allows for the quantitative assessment of different types of airborne microorganisms, including molds, by analyzing the collected samples for their size, quantity, and morphology. This type of sampling is particularly valuable in mold assessment because it provides a snapshot of the airborne mold spores present in a given environment without requiring cultivation. It enables technicians to evaluate the specific types of spores and their concentrations, which can inform decisions regarding remediation and health risk assessments. The other options present functions that are not primary to non-viable sampling methods. Culturing mold samples is associated with viable air sampling, which seeks to grow and propagate living spores. Assessing overall air quality encompasses a broader range of factors than just mold spore enumeration and could involve various pollutants and particulates that are not specifically collected by non-viable methods. Lastly, measuring humidity levels in the air pertains to environmental conditions rather than the analysis of airborne particles themselves. Thus, the focus on direct enumeration and identification distinguishes non-viable air sample collection as an essential tool in mold assessment
