What must be done after the pumps start in a sampling process?

After the pumps start in a sampling process, it is essential to allow the system to stabilize before recording flow rates. The recommended time frame of 15-30 minutes allows for any fluctuations in the flow rate to settle and ensures that the readings taken are representative of the actual conditions during the sampling period. This stabilization period is important because immediate readings can be skewed by initial variances that often occur when pumps begin operating, which can lead to inconsistent data that may not accurately reflect airborne asbestos levels.

Establishing a proper sampling rate is critical, as it ensures the integrity and reliability of the results. Sampling protocols often dictate a specific waiting period because taking measurements too soon can result in inaccuracies, which may cause misleading assessments of air quality concerning asbestos exposure.
