What should be done after sampling is completed?

After sampling is completed, it is crucial to ensure that the collected samples are handled properly for accurate analysis. Shipping the samples to a laboratory for analysis with a chain of custody form is essential because it documents the handling of the samples from the point of collection until analysis. This chain of custody helps maintain the integrity and validity of the samples, ensuring that they are not tampered with or contaminated during transport. Proper documentation provides traceability and accountability, which is vital in occupational hygiene to uphold standards and regulatory requirements.

While cleaning the sampling equipment is important for future sampling, it does not address the immediate next step after collecting samples. Analyzing the samples immediately is generally not feasible, as many sampling methods require careful handling and transport to ensure the samples remain representative of the exposure situation. Discarding the samples would defeat the purpose of collecting them in the first place, as it would prevent any analysis from being conducted. Properly shipping samples with a chain of custody ensures they can be analyzed accurately and reliably, making it the correct action to take after sampling.
