Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

For a facility with 7102 square feet of sprayed-on fireproofing, what is the minimum number of samples required?

1. 5 samples

2. 6 samples

3. 7 samples

4. 8 samples

The correct answer is: 7 samples

The correct answer regarding the minimum number of samples required for a facility with 7102 square feet of sprayed-on fireproofing is based on the guidelines provided by the Asbestos Hazard Emergency Response Act (AHERA). According to AHERA regulations, when determining how many samples to collect for asbestos inspection, specific formulas are used depending on the area being evaluated. For materials like sprayed-on fireproofing, a common sampling protocol suggests that an initial quantity of at least one sample needs to be collected for the first 1,000 square feet, and then for each additional increment of area, more samples should be added. Typically, for areas greater than 1,000 square feet, the rule of thumb is to collect additional samples in increments, which often results in a requirement for several total samples. In this scenario, the area of 7102 square feet warrants the collection of more samples to adequately characterize the material's condition and ensure a proper assessment of potential asbestos presence. The minimum requirement indicated, which is seven samples, aligns with established guidelines to ensure a comprehensive evaluation of the material. Each sample helps to provide a better understanding of the spread of asbestos within the fireproofing material. The rationale for needing at least seven samples is to account for the
