OSHA 30 Hour Construction Program Practice Test

In which classification of asbestos might repair jobs occur?

1. Class I

2. Class II

3. Class III

4. Class IV

The correct answer is: Class III

Class III asbestos work involves repair and maintenance activities where workers handle materials that contain asbestos. This classification is crucial because it specifically targets situations where asbestos-containing materials (ACMs) may need to be disturbed or repaired, potentially releasing asbestos fibers into the air. Typical activities might include repair of insulation, ceiling tiles, and other components that are likely to have asbestos. Understanding Class III is vital since it requires proper training, equipment, and safety measures to handle the health risks associated with asbestos exposure. Workers engaged in such activities need to be aware of the proper procedures to minimize exposure and ensure that they comply with OSHA regulations. The other classifications, while related to asbestos work, do not primarily focus on repair jobs. Class I deals with removal of asbestos-containing materials, Class II involves the removal of materials that likely contain asbestos but are not specifically designed as such, and Class IV pertains to maintenance or custodial work where asbestos is present but not disturbed.
