What is critical regarding the recorded flow rate of a sampling pump?

The recorded flow rate of a sampling pump is critical because it relates to the reliability and accuracy of the air sampling that is being conducted. When evaluating the performance and effectiveness of the sampling process, it is essential to compare the recorded flow rate to the average flow rate at the end of the sampling period. This comparison allows you to detect any inconsistencies or anomalies that might indicate a problem with the sampling process, such as a decrease in flow due to a clogged filter or leaks in the system. Ensuring the recorded flow matches the average can help verify that the sampling was conducted under representative conditions, which is vital for making accurate assessments regarding asbestos exposure levels.

This emphasis on comparing the recorded flow rate to the average flow rate highlights the importance of consistency during sampling and the ability to recognize any changes that could affect the results. Such practices ensure that regulatory requirements are met and contribute to the safety and health of individuals potentially exposed to asbestos.
