New York State Asbestos Investigator Practice Exam

Which factor is NOT relevant when determining exposure risks for asbestos-containing materials (ACM)?

1. Air movement and ventilation

2. Character of occupants

3. Time of exposure during remodeling

4. Age of the building alone

The correct answer is: Age of the building alone

The determination of exposure risks for asbestos-containing materials (ACM) requires an understanding of several key factors that influence how and when individuals may come in contact with asbestos fibers. The age of a building alone lacks relevance because it does not provide sufficient context regarding the specific conditions or circumstances that could lead to asbestos exposure. For instance, while older buildings are more likely to contain ACM due to historical construction practices, simply knowing the building's age does not account for factors such as air movement, ventilation, the nature of the occupants (who may have varying sensitivity or exposure levels), or the timing and nature of any remodeling work being conducted. These aspects are critical in assessing potential exposure risks, as they address how asbestos may be disturbed, whether its fibers are likely to enter the air, and the overall environment in which individuals may be present. In summary, focusing solely on the age of a building does not capture the dynamic variables affecting exposure risks, which is why this factor is deemed irrelevant in this context.
