The correct procedure for handling a contaminated sample of fuel involves vortexing the fuel sample, draining a gallon into a bucket, and setting it aside. This process is crucial because it allows for a thorough assessment of the contamination present in the fuel. Vortexing ensures that any particulates or other contaminants are fully suspended, which helps to provide an accurate representation of the contamination level in the sample. By draining a gallon, you can remove the potentially contaminated fuel from the system, which prevents any further issues with fuel contamination in the aircraft or equipment.

Setting the sample aside is also important, as it ensures that there’s a retained sample for further analysis or inspection, which may be necessary for verifying the type and extent of the contamination. This step is essential for maintaining aviation safety and operational integrity, as contaminated fuel can lead to significant problems if it reaches the aircraft’s fuel system.

In contrast, simply taking it to a supervisor may not address the immediate need to assess and handle the contamination. Leaving it for inspection is passive and does not involve any immediate action to mitigate potential risks. Suggesting there is no procedure neglects the importance of having clear protocols in place to manage fuel quality and safety effectively.
