Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

Which type of particulate cartridges are utilized for asbestos sampling?

1. HEPA P100

2. HEPA MERV 13

3. Carbon filter

4. Standard N95

The correct answer is: HEPA P100

Particulate cartridges designed for asbestos sampling are typically HEPA P100 filters. These filters are recognized for their ability to capture at least 99.97% of airborne particles that are 0.3 microns or larger, which includes asbestos fibers. The P100 classification indicates a higher level of filtration efficiency compared to other types of filters, making them essential for environments where asbestos is present. Using a HEPA P100 filter ensures that the risk of inhaling harmful asbestos fibers is minimized during sampling and assessment. This is critical in compliance with the Asbestos Hazard Emergency Response Act (AHERA), which mandates strict safety protocols and the use of appropriate personal protective equipment to prevent asbestos exposure. The other options, while they may provide some filtration, do not meet the stringent requirements necessary for effective asbestos sampling and exposure prevention. For example, HEPA MERV 13 is not standardized for personal respiratory protection against asbestos. Carbon filters are used primarily for odor removal and do not filter particulates like asbestos. The standard N95, although it offers some filtration, does not provide the same level of protection as a HEPA P100 filter in environments containing asbestos. Therefore, the choice of HEPA P100 is both necessary and appropriate for ensuring safety and
