Which of the following is a common method of monitoring asbestos exposure?

Personal air sampling is a common method used to monitor asbestos exposure because it involves collecting air samples from the work environment to measure the concentration of asbestos fibers present in the air. This method provides quantitative data that helps assess the level of exposure workers may have to asbestos. By analyzing these air samples in a laboratory, it is possible to determine whether the exposure levels exceed safety standards set by regulatory agencies, ensuring that workers' health is adequately protected.

Visual inspections and environmental impact assessments are important in identifying the presence of asbestos in buildings or sites, but they do not provide direct measurements of airborne asbestos levels. Health screening tests are useful for monitoring the health effects of past exposure but do not measure current exposure levels specifically. Therefore, personal air sampling is the most effective method for directly monitoring asbestos exposure in real time.
