What should be done with a second sample if the first fuel sample is bad?

When the first fuel sample is determined to be bad, taking both samples to Quality Assurance (QA) is crucial. This step ensures that both the initial and subsequent samples are evaluated for compliance with safety and quality standards. By doing so, it allows QA personnel to conduct a thorough assessment and determine the cause of the bad sample. They can analyze the fuel source, inspect the handling procedures, and possibly identify systemic issues with fuel storage or delivery.

Storing a bad sample for future reference does not provide the necessary action to address the potential contamination or problem in the fuel supply, and discarding both samples would eliminate valuable evidence needed to assess the situation. Utilizing the second sample for testing may seem logical, but without QA's involvement, it risks overlooking critical safety procedures and potential hazards.

Involving QA establishes a proper protocol for investigating the issue, ensuring that safety is prioritized, and that any necessary corrective actions are taken based on a comprehensive analysis of both samples.
