What action should a technician take if a calibration issue is detected with sampling equipment?

When a technician detects a calibration issue with sampling equipment, it is crucial to take the appropriate steps to ensure accurate measurements. Recalibrating the equipment before proceeding with air sampling is essential because calibration ensures that the instruments provide precise and reliable data. If the equipment is not properly calibrated, the results could be erroneous, leading to potentially dangerous conclusions about the presence of asbestos or other hazardous materials.

Recalibration is a methodical process that rectifies any drift or error that may occur over time. Ensuring that sampling equipment is functioning correctly is vital for compliance with safety standards and guidelines, as well as for maintaining the integrity of air sampling results. Addressing calibration issues promptly not only protects the technician and others in the vicinity but also upholds the credibility of the monitoring process.

Taking any of the other actions, such as ignoring the issue, replacing the equipment immediately, or continuing sampling, would compromise the quality of the data collected and could lead to significant safety risks.
