Asbestos Contractor/Supervisor Practice Exam

Which of the following is identified as a primary device for calibration in asbestos testing?

1. Electronic Balance

2. Single Gas Detector

3. Electronic Bubble Meter

4. Integrated Sampling Pump

The correct answer is: Electronic Bubble Meter

The electronic bubble meter is identified as a primary device for calibration in asbestos testing due to its ability to accurately measure the volume of air samples collected over time. This calibration is crucial for ensuring that the sampling process is reliable and that the measured asbestos concentrations are precise. The electronic bubble meter typically utilizes a liquid-filled device to control the airflow and record the volume of air passing through the apparatus, which is essential for determining the concentration of asbestos fibers in the air. In contrast, while other devices like the electronic balance, single gas detector, and integrated sampling pump are essential in the context of asbestos handling and measurement, they serve different roles. The electronic balance is primarily used for measuring weights, while the single gas detector focuses on individual gas detection, and the integrated sampling pump is primarily responsible for collecting air samples rather than calibrating them. Hence, in the context of calibration specifically for asbestos testing, the electronic bubble meter is the most suitable choice.
