What is one requirement for personal sampling pump calibration?

Calibration before and after each use is essential for personal sampling pumps to ensure accurate measurements of airborne contaminants. This requirement ensures that the pump operates within specified parameters, providing reliable data that reflects the actual exposure levels workers may experience. Proper calibration accounts for any variations that might occur in pump performance over time or due to environmental factors.

Regular calibration gives confidence in the readings obtained during sampling, as inconsistent calibration could lead to significant errors in exposure assessments, potentially impacting worker safety and regulatory compliance. By adhering to this requirement, employers can ensure that they are effectively monitoring the level of asbestos exposure, thus protecting the health of workers and adhering to regulatory standards.
